Steps for selecting a pressure switch

The deciding factors in the selection of a pressure switch for use on control circuits1 depend on the

requirements of the application. Consider the following requirements to help determine the

appropriate catalog number for your application.

1. Setpoints: Do you want to control/monitor one setpoint or two?

• One setpoint: xed differential • Two setpoints: adjustable differential

2. Fluids: What uids do you want to control?

• Hydraulic oil, air, fresh water ≤ 70 °C (158 °F) • Steam

• Hydraulic oil, air, fresh water ≤ 160 °C (320 °F) • Corrosive uid ≤ 160 °C (320 °F)

• Sea water ≤ 70 °C (158 °F) • Viscous uid ≤ 160 °C (320 °F)

• Sea water ≤ 160 °C (320 °F)

Ensure that the wetted parts of the switch are compatible with the system uid.

3. Pressure range: What pressure range does the system experience?

Note: Select pressure settings that fall within the middle 80% of the pressure range. The pressure

applied during a normal cycle should never exceed the maximum range value listed for the switch.

Pressure surges should be less than the maximum allowable pressure listed for the switch.

device for these products.) Some examples are:

• Pilot light

• Prewired receptacles

• External range adjustment

• Range scale window

• Special factory pressure settings

• Pressure connections

When switches must be factory set and only one setting is identied, specify whether this setting

is on rising or falling pressure. See “Special factory setting specied (If indicating only one

special setting, specify whether this setting is on increasing or decreasing pressure.)” in the

modication table on page 8/91.

11. System response time

• If system response time is critical, select a switch with a volumetric displacement that is

compatible with the overall system. See the table below .

Terminology

Measuring range

The measuring range (MR) of a pressure sensor corresponds to the difference

between the upper and lower values measured by the load cell. It ranges between 0

and the pressure corresponding to the size of the sensor.

Operating range

The operating range of a pressure transmitter corresponds to its measuring

range. Within this range, its analog output signal varies between 4 and 20 mA or 0

and 10 V, and is proportional to the measured pressure.

The operating range of a pressure or vacuum switch is the difference between

the values of the minimum low setpoint (PB) and the maximum high setpoint (PH).

Precision

This includes linearity, hysteresis, repeat accuracy, and setting tolerances. It is

expressed as a percentage of the measuring range of the load cell (%MR).

The linearity is the maximum deviation

between the real transmitted curve and

the ideal curve.

The hysteresis is the maximum

deviation between the rising pressure

curve and the falling pressure curve.

The repeat accuracy is the maximum

drift encountered at varying pressures

under given conditions.

The setting tolerances are the

manufacturer's tolerances with regard

to the zero point and sensitivity

(gradient of output signal curve from

pressure transmitter).

Temperature drift

The precision of a pressure sensor is susceptible to variation due to the operating

temperature.

Zero point drift, proportional to the

temperature, is expressed as %MR/°C.

Sensitivity drift, proportional to the

temperature, is expressed as %MR/°C.

Terminology (continued)

Switching point on rising pressure (PH)

This is the upper pressure setting at which the output of the electronic pressure or

vacuum switch changes state on rising pressure.

Switching point on falling pressure (PB)

This is the lower pressure setting at which the output of the electronic pressure or

vacuum switch changes state on falling pressure.

Differential

This is the difference between the switching point on rising pressure (PH) and the

switching point on falling pressure (PB). The low point can be set at the values

indicated on the operating curves shown on the product pages.

Switches with xed differential

Depending on the switch, either the high or low operating point is adjustable, and

the other operating point follows. The window is xed.

Switches with adjustable differential

An adjustable differential allows independent setting of both operating points.

Spread

For dual-stage switches, the spread indicates the difference between the two

operating points on rising pressure (PH2 and PH1) and, for vacuum switches, the

difference between the two operating points on falling pressure (PB2 and PB1).

Differential-pressure sensing

Switches for differential-pressure sensing measure the difference between two

pressures.

Size

Pressure transmitters and pressure switches

This is the maximum value of the operating range.

Vacuum transmitters and vacuum switches

This is the minimum value of the operating range.

+

–

Setting point

Accuracy (switches with setting scale)

The tolerance between the point at which the switch actuates its contacts and the

value indicated on the setting scale. Where very high setting accuracy is required

(initial installation of the product), it is recommended that you use separate

measuring equipment (pressure gauge, etc.).

R

Repeat accuracy

This is the variation in the operating point between several successive operations,

or the tolerance between two consecutive switching operations.

F

Drift (F)

The tolerance of the operating point throughout the entire service life of the switch.

Maximum allowable pressure

The maximum value of an accidental pressure surge of very short duration (a few

milliseconds).

Maximum permissible accidental pressure

This is the maximum pressure (excluding pressure surges) that the sensor can

occasionally withstand without permanent damage.

Maximum allowable pressure per cycle (Ps)

The maximum pressure level per cycle that the switch can withstand for optimum

service life.

Surge

A surge is a high rate of rise in pressure, normally of short duration, caused by

starting a pump or by opening and closing a valve. Depending on frequency and

duration, surge can reduce service life. Extremely high rates of rise in pressure can

be damaging even if they are within the limits of the maximum allowable pressure.

Destruction pressure

Also called burst pressure, the destruction pressure is the pressure value which, if

exceeded, is likely to cause serious damage to the sensor—such as leaking,

bursting, or permanent damage.

Load resistance of pressure transmitters

The supply voltage and load resistance of a pressure transmitter must be selected

according to the following formula:

R load = U supply – U supply min. (U supply min = 11 V for XMLE and 17 V for XMLF)

Function

Pressure and vacuum switches control or regulate pressure or vacuum levels in

hydraulic or pneumatic systems. They transform the pressure change into a digital

electrical signal when the preset operating points are reached.

Switches for control circuits

Switches with control-duty rated electrical contacts, designed for control of

contactors, relays, power valves, PLC inputs, etc.

Switches for power circuits

Switches with power electrical contacts (1, 2, or 3 pole) designed for direct switching

of single-phase or three-phase motors (pumps, compressors, etc.).

Pressure switch operating principle

Fixed Differential: Detection of a Single Threshold

Fixed differential switches have

a single adjustable setting point

(either PH or PB). The

differential between the high

and low points (PH–PB)

Vacuum switch operating principle

Detection of a single threshold

The switches for detection of a single threshold (xed differential) have a single

adjustable setting point (PH). The differential between the high and low points (PH–

PB) depends on the inherent characteristics of the switch. It is not adjustable.

–– Adjustable value

--- Nonadjustable value

PH = High point

PB = Low point

Example: Contact

schematics of XMLA

Regulation between two thresholds

The switches for regulation between two thresholds (adjustable differential) have

both a high point setting (PH) and a low point setting (PB). Both of these points can

be independently adjusted.

–– Adjustable value

PH = High point

PB = Low point

Example: Contact

schematics of XMLB

Detection of two thresholds

The dual-stage switches, for detection at each threshold, have an adjustable high

point setting for each stage (PH1 and PH2). Both of these points can be

independently adjusted.

For both stages, the differential between the high point and the low point (PH1–PB1 and

PH2–PB2) depends on the inherent characteristics of the switch. It is not adjustable.

–– Adjustable value

--- Nonadjustable value

PH = High point

PB = Low point

Example: Contact schematics of XMLD

Maximum allowable accidental pressure

The maximum accidental pressure of XML switches is equal to at least 2.25 times

the switch size.

If accidental overpressures occur and their duration is less than 50 milliseconds, the

pressure damping device incorporated in the XML switches (sizes 10 bar and

greater) reduces the effect.

Selecting the switch size

After establishing the type of switch required for the application (single threshold

detection or regulation between two thresholds), the selection of its size depends on

the following criteria:

b the differential: difference between the high point (PH) and the low point (PB),

b the maximum pressure allowable per cycle,

b repeat accuracy, precision and minimum drift.

Selecting a xed differential pressure switch for detecting a

single threshold

Main criterion: minimum differential

Example: for a selected high point (PH) of 7 bar

XMLA010•••••

Differential = 0.5 bar

XMLA020•••••

Differential = 1 bar

XMLA035•••••

Differential = 2 bar

Select an XMLA010••••• (the lowest size)

Main criterion: tolerance to overpressures

Example: for a selected high point (PH) of 12 bar

XMLA020•••••

Allowable accidental overpressure = 45 bar

XMLA035•••••

Allowable accidental overpressure = 80 bar

Select an XMLA035••••• (the highest size)

Main criterion: repeat accuracy, precision and minimum drift

Example: for a selected high point (PH) of 18 bar

As a general rule,

avoid working at

the upper or lower

limits of the

operating range.

The difference between the operating

The 9012G pressure switches are UL Listed and CSA certied as industrial control

equipment. They are used to interface pneumatic or hydraulic systems with electrical

control systems by opening or closing electrical contacts in response to pressure

changes in the system. They have outstanding repeatability and drift performance.

Their efcient design uses durable, low mass components for excellent performance

under heavy duty vibration and shock conditions.

The 9012G pressure switches line offers devices with either diaphragm or piston

actuators—for optimum life, versatility, and speed of operation. Features include the

following:

b High shock resistance b Dual numerical range scale (psi and kPa)

b High set-point stability b One or two SPDT double-break contacts

b Internal or external range

adjustment

b Adjustable or xed (nonadjustable)

differential

b No drain line required b Single-stage, dual-stage, or differential-

pressure operation

A variety of modications is available (see also page 12):

The 9012G diaphragm switches range from 0.2–675 psi falling pressure. Nitrile

diaphragms and zinc-plated steel anges are standard. Diaphragms of Viton®

uorocarbon or ethylene propylene are available as well as stainless steel anges.

The 9012G piston-actuated switches range from 20–9,000 psi falling pressure.

They have sealed pistons and can be used on air, water, oil, or any media compatible

with the actuator material. The switches come standard with stainless steel pistons

and housings, Viton diaphragms and O-ring seals, and Teon® retaining rings.

Ethylene propylene diaphragms and O-ring seals are also available.

The 9012G industrial pressure switches are available as open type or in NEMA 1

enclosures. The backplate is steel with a plastic cover. Open devices in pressure

ranges up to 250 psi are available with internal- or external-threaded pressure

connectors, ideally suiting them for panel mounting.

The 9012G machine tool pressure switches with NEMA 4, 4X, or 13 (IP66) cast

aluminum enclosures are UL Listed and CSA certied as industrial control

equipment. They are also UL Marine Listed for use on vessels greater than 65 ft long

where ignition protection is not required.

The 9012G machine tool switches are also available in NEMA 7 & 9 cast aluminum

enclosures. These are UL Listed for use in Class I, Divisions 1 and 2, Groups C and

D, and Class II, Divisions 1 and 2, Groups E, F, G hazardous locations.

Application and general information

9012 pressure switches can generally be used in any application where electrical

contacts must open or close in response to a system pressure change, within the

electrical and pressure ratings of the switch. Pressure switches are used in a wide

variety of applications such as the following:

b compressed air systems b stamping presses

b HVAC equipment b automatic grinders

b chillers b welders

b pumping systems b process equipment

b machine tools b molding machines

Pressure switches typically perform one of the following two functions:

Monitoring the pressure in the system. The switch can be used either as an interlock

that sequences operations in an automatic system, or to give an audio or visual

signal, typically an alarm of an undesired condition, at predetermined pressures. A

switch with a xed differential is generally used in these applications.

Controlling the pressure in the system by starting and stopping a pump or a

compressor at predetermined pressures. A switch with an adjustable differential is

usually needed in these applications.

Diaphragm life

The elastomer diaphragms used on 9012G switches can withstand high speed

cycling and wide pressure changes. They can tolerate operating speeds up to 200

cycles per minute with no negative impact on the life of the diaphragm.

Diaphragm life is affected by pressure medium compatibility. Standard diaphragms

on 9012G devices are nitrile in zinc-plated steel anges. Also available are Viton

uorocarbon and ethylene propylene diaphragms, as well as Type 316 stainless

steel anges.

The diaphragm can withstand wide pressure changes on each operating cycle.

However, the pressure applied to the diaphragm during the normal operating cycle

should never exceed the maximum value listed in the Range column in the catalog

listing. Regularly cycling the pressure above this value reduces life considerably. If

signicant surges are common, or if pressures are higher than those listed in the

Range column, consider using a piston device.

Piston life

For long piston life, the pressure medium should be ltered to keep foreign matter

such as dirt and chips out of the piston assembly. 9012G sealed piston devices are

not recommended for use on dry gas media, since this usage could cause some

leakage past the seal. Depending on the gas, the media pressure, and the rate of

operation, the amount of leakage could render the switch inoperable. (Note,

however, that some weepage of the media is necessary to lubricate the seals. This

small amount of weepage does not indicate a problem.)

Surges

One of the most destructive conditions for a pressure switch is hydraulic surge. A

surge is a high rate of rise in pressure, normally of short duration, caused by starting

a pump or by opening and closing a valve. Extremely high rates of rise in pressure

can be damaging even if they are within the limits of the maximum allowable

pressure.

To limit the effect of surges, the switch should be mounted as close to an

accumulator and as far from the pump or quick acting valve as possible. The 9012G

piston-actuated switches have a 0.020 in. pressure orice to help reduce the effects

of minor surges. 9012G diaphragm-actuated switches have a 0.060 in. pressure

orice. A restrictor with a small orice placed in the line between the switch and the

pump or valve will further help to protect the switch. Using a surge snubber such as

the 9049A26 or A26S will also protect the switch.

Vibration

Among other things, excessive vibration can cause contact bounce, chatter, or

premature contact transfer, especially when system pressure is near the operating

point of the switch. Remote mounting of the switch is the best way to avoid problems.

Use on steam

Switches should not be applied directly on steam exceeding 15 psig. However, with

steam capillary tubing installed between the pressure connection and the switch,

steam pressure up to 250 psig can be applied—provided this does not exceed the

maximum allowable pressure rating of the switch or the maximum temperature rating

at the actuator. Refer to the instruction bulletin supplied with the device.

Dual-stage operation

The 9012G dual-stage pressure switches provide two distinct levels of control from

one device. These switches are most commonly used where dual functions are

required, or in sequencing applications such as alarm-shutdowns.

Differential-pressure operation

The 9012G pressure switches for differential-pressure sensing can monitor changes

in the difference between two pressures. These unidirectional devices signal that a

predetermined pressure difference was reached, resulting from a widening or

narrowing of the difference between two pressures.

Piston- vs. diaphragm-actuated devices

Whether to select a piston or diaphragm device depends on several criteria:

b maximum allowable pressure

b range and differential

b surges

b medium (whether hydraulic or pneumatic)

Maximum allowable pressures for piston devices are much higher than for

diaphragm devices. Most diaphragm devices have a maximum allowable pressure of

850 psi or less, whereas all piston devices have a maximum allowable pressure of

10,000 psi or more.

Range and differential for diaphragm devices are lower than for piston devices.

Many applications call for a low differential, such as 20 psi. This may exclude piston

devices, which have a minimum differential of 60 psi or more.

Surges are a part of every hydraulic system. While many are small and have only a

small effect on the switch, some are signicant and can potentially destroy a

pressure switch. Diaphragm devices are the most sensitive to surges and are most

easily damaged. Piston devices are more tolerant of surges and last longer in the

same application.

Hydraulic systems, which typically use oil-based media, are more demanding

applications than pneumatic systems. Pressure switches used in hydraulic

applications typically experience higher pressures, have wider pressure variations,

and produce more surges, since the medium does not compress. Pneumatic

systems, which typically use air, place fewer demands on a system, since these

applications typically experience lower pressures and the medium can compress,

cushioning the effects of surges. Table 1 offers basic guidelines for determining the

selection of a piston- versus a diaphragm-operated pressure switch.

Operating points (set points)

Pressure switches have two operating points:

b Increasing pressure (rising pressure)

b Decreasing pressure (falling pressure)

These operating points are also called the set points of the switch.

Differential

The differential is the difference in pressure between the rising and falling pressure

points. It can be adjustable or xed.

Range

The range refers to the pressure limits within which the operating points (settings)

can be adjusted. The range of the 9012G pressure switch is tied to the decreasing

pressure operating point. Adding the differential to the decreasing pressure

operating point determines the increasing pressure operating point.

Differential

Fixed differential

To determine the operating range on rising pressure for a xed differential switch,

add the differential to the decreasing pressure operating point. For example, to

determine the range on increasing pressure for a 9012GDW5 switch:

b Range on decreasing pressure = 3 to 150 psi

b Fixed differential = 6.0 ± 0.8 psi

b Range on increasing pressure = 9 ± 0.8 to 156 ± 0.8 psi

Adjustable differential

For adjustable differential switches, add the minimum differential to the low end of

the range and the maximum differential to the high end of the range. For example, to

determine the range on increasing pressure for a 9012GAW5:

b Range on decreasing pressure = 3 to 150 psi

b Adjustable differential = 6.0 to 30 psi

b Range on increasing pressure = 9 to 180

During the normal operating cycle, system pressure should never exceed the upper

limit of the range when using a diaphragm-actuated switch. This greatly reduces the

life of the diaphragm. For optimum life, operate the switch in the middle 80% of the

range.

Maximum allowable pressure

Maximum allowable pressure is the pressure to which a switch can be subjected

without causing a change in operating characteristics, shift in settings, or damage

to the device.

System pressure surges may occur during machine startup or from valve operation.

Surges are not normally detrimental to the life of a switch if the surge is within the

maximum allowable pressure rating of the switch. Diaphragm-actuated switches

should not be subjected to more than 10 surges per day. More frequent surges

greatly reduce the life of the diaphragm.

Differential-Pressure Operation

Pressure switches for differential-pressure operation are used to monitor the change in the difference between

two pressures. The 9012G differential-pressure switches are unidirectional devices and are used in applications to

signal that a predetermined pressure difference has been reached as a result of a widening or increasing difference

between the two pressures. They can also be used in applications to signal that a predetermined pressure

difference has been reached as a result of a narrowing or decreasing difference between the two pressures.

NEMA 4, 4X, and 13 devices are suitable for use in Class I, Division 2, Groups A, B, C, and D hazardous locations

or nonhazardous locations only.

Dual-Stage Operation

The 9012G dual-stage pressure switches are designed for use in applications where two separate pressure

operations must be controlled by a single pressure monitoring device. These controls are most commonly used

where dual functions are required or in sequencing applications such as alarm shutdowns. The spread between

the two stages is adjustable, but the differential between the high (rising) and low (falling) operating points of each

stage is xed.

NEMA 4, 4X, and 13 devices are suitable for use in Class I, Division 2, Groups A, B, C, and D hazardous locations

or nonhazardous locations only.

9016GAW Switches for Sensitive Control Applications

9016GAW vacuum switches have double throw contacts. Normally open and normally closed circuits allow the

use of these controls for standard or reverse action applications.

Standard controls can be mounted from the front using the bracket provided. Two mounting screws are required for

rm attachment to any smooth, at surface. Allowance must be made for ange projection.

Controls with the Form F modication include two mounting feet with 9/32” mounting holes on 3–3/4 in. centers.

The Range and Differential adjustments are accessed by removing the front cover.

■ Maximum allowable positive pressure: 100 psig.

■ Diaphragms are oil resisting, nitrile butadiene rubber (Buna-N).

■ For electrical ratings and temperature limitations, see table on page 8/83.

■ For dimensions and modications, see page 99.
