Technical Data
Series 7615
Ruska Hydraulic
Pressure Controllers
Features
• Precision to 0.01 %
• Pressure ranges up to
40 000 psi (275 MPa)
• Six pressure ranges available in one
instrument
• Automatic cyclic and fatigue testing with
high speed control
• Automate high pressure test and calibration
The Series 7615 hydraulic pressure controller
introduces a new approach to automatic test-
ing of high pressure transducers, sensors and
instruments. The Series 7615 is the result of
combined technologies developed over the last
10 years. Using the pulse-width modulated
valves (the same used in the Series 7250), a
unique pneumatic to hydraulic intensifier has
been developed that allows simple, automated
high pressure control of pressures up to
40,000 psi (275 MPa).
The Series 7615 provides fast, accurate
pressure control where the pressure setpoint is
achieved quickly, even when controlling into a
50 cc load volume. This combination of speed,
pressure range and compatibility with virtually
any liquid medium, is unique to the Series 7615.
The Series 7615 is an excellent choice for
automating pressure calibrations that were pre-
viously performed manually wtih hand pumps/
deadweight testers in applications such as:
• High volume transducer manufacturing such
as diesel fuel rail sensors and transducers.
• High pressure automotive transducers such as
those used in braking systems.
• Pressure sensors used in downhole tools for
oil and gas applications
• Throttle body pressure sensors.
• Any application that involves high pressure
test or calibration using a liquid medium for
safety, compatibility or other concerns.
The Series 7615 increases throughput and
reduces cost through speed and automation
without sacrificing performance.
The Series 7615 offers a variety of pressure
ranges to 40 000 psi (275 MPa), with IEEE 488
and RS-232 digital interfaces for a complete
automated solution. The remote communication
syntax uses the SCPI format and is compatible
with the Series 7000 pressure indicators and
controllers.
2 Fluke Calibration Series 7615 Ruska Hydraulic Pressure Controllers
Pressure control
The control parameters in the Model 7615 are
optimized to provide the fastest rate of pressure
change with minimal overshoot. At the end
of the test, the pressure can be vented to the
reservoir for rapid depressurization or reduced
under control. If the piston reaches the end of
travel before the minimum setpoint pressure
is achieved, then there will be an automatic
recharge cycle. Actual times will depend on
medium selection, system volume, geometry and
device under test. Typical control time into a
50 cubic centimeters volume and 10 % steps
within the control stability specification would
be 90 seconds.
Automating high pressure test and
calibration
The Model 7615 features an easy-to-use, menu-
driven user interface for straightforward, simple
operation.
Step up/down: For calibrations where the
increments are fixed intervals, enter a user-
defined step value. The controller increases or
decreases the pressure by the step amount with
a single keystroke. No more lengthy keystroke
sequences to program.
Sweep test: For simple exercising routines,
as with dial gauges, enter a start value, a stop
value and number of times to repeat the cycle.
The controller automatically exercises the device
under test prior to the calibration run.
Onboard programs: For frequently used or
lengthy calibrations, the controller can store up
to 20 user-defined programs/profiles with up to
a total of 1000 steps in internal memory.
Computer interface: Every controller is
provided with both an RS-232 and IEEE-488
interface, and the controller syntax follows SCPI
protocol for easy programming. A LabVIEW®
driver is also available.
COMPASS® for Pressure Software: Provides
complete automation of pressure calibrations. A
ready-to-use software package that interfaces
with all Fluke Calibration pressure controllers,
along with other devices to provide closed loop
calibrations. Compass also provides calibration
management solutions by providing a printout
of calibration results and performance analysis,
and stores historical data.
Pressure units/scales: Features two user-
defined, programmable units of measure, and
twelve standard units: inHg at 0 °C, inHg at
60 °C, kPa, bar, psi, inH2O at 4 °C, inH2O at
20 °C, inH2O at 60°F, kg/c2, mmHg at 0 °C or
cmH2O at 4 °C
Head pressure: Automatic correction for
given head pressure differences
Protection of the device under test: Set
upper and lower pressure limits to ensure
protection of the device under test.
The Series 7615 also offers the following addi-
tional modes of operation:
Cyclic mode
Ideal for fatigue testing or extended proof pres-
sure cycling. First, the user sets the desired
maximum pressure value for the cycle. The
Series 7615 controls the maximum pressure and
once achieved, it moves the pump to the home
or starting position to establish the minimum
pressure value for the cycle. The minimum value
obtainable is dependent on the device under
test volume and medium. Therefore it cannot
be defined by the operator in this mode, (If the
lower pressure value must be defined, please
see sweep operation). The pressure is then
cycled between the maximum and minimum
pressure values. The Series 7615 will cycle
between the maximum and minimum pressure
until the preset number of cycles defined by the
operator have been achieved. The profile of the
cycle (rate of pressure change and dwell time
at maximum and minimum pressure values) can
also be defined.
Sweep mode
This is similar to cyclic mode except that in
sweep mode the lower pressure point is also
controlled.
