Description
In connection with suitable Wtrans receivers, the Wtrans probe is used for the mobile
and stationary measurement of temperatures within the range of -30 to +260 °C. The
ambient temperature of the electronic components in the handle may be -30 to +85
°C. The measured temperature value is transmitted wireless to the receiver of the
Wtrans system. The radio frequency within the ISM band is 868.4 MHz or 915 MHz.
These frequencies are largely insensitive with regard to external perturbations and
enable transmissions in crude industrial conditions. If the recommended antenna wall
mounting is used, the maximum open air range is 300 m.
The handle contains the transmitter unit of the resistance thermometer. The unit is designed to be resistant against vibrations, oils and acids.
The protection class is IP67. The stainless steel thermowell is available with a flat,
concentric or oblique insertion tip. The fitting length extends from 50 to 1000 mm.
The measuring insert contains a serial Pt 1000 temperature sensor to EN 60 751,
Class A in 3-wire-circuit.

4 Range of Transmission
4.1
General remarks on wireless transmission
Radio signals are magnetic waves with their signal becoming weaker on their path
from the probe to the receiver (this phenomenon is referred to as loss). Both the electric and the magnetic field strength are decreased inversely proportional to the
squared distance between the probe and the receiver.
In addition to this natural limitation of the range of transmission, a reduced transmission range can also occur due to other circumstances:
• Reinforced concrete walls, metal devices or surfaces, heat insulation or metal
evaporated heat protection glass reflect electro-magnetic waves and therefore a
so-named radio shadow or blind spot occurs behind such objects.
• Radio shadows within the transmission link
• The antenna is installed in too low a position, therefore mount antenna in as high
a position as possible above the floor within a visual range between probe and
receiver.
A few guiding values on penetration by radio signals:
Materials
Penetration
wood, gypsum, non-laminated glass
90 to 100%
walling/brickwork, chipboards/fibreboards
65 to 95%
glass-fibre reinforced concrete
10 to 90%
metal, aluminium casings
0 to 10%
The maximum transmission range between the probeprobe and the receiver is 300
meters in a free field. Ideal reception can be obtained if visual contact can be maintained between the receiver and the probe.
In case the receiver is installed in a switching cabinet, behind concrete walls or concrete ceilings, it is indispensable for the antenna to be installed in a wall-mount fashion and including an antenna conduit.
4.2
Impairment of the range of wireless transmission
Collision due to prevalence of too many probes
For a comparatively large number of probes, the transmission interval should not be
set too short, as otherwise the transmission frequency will superfluously be occupied. A short interval means a higher volume of data on the selected frequency, which
can lead to collisions with other probes. Through such collisions telegrams might be
destroyed during radio transmission.
11
4 Range of Transmission
12
Figure 5:
Telegrams of one probe are transmitted to the receiver collision-free.
Figure 6:
Telegrams of various probes increasingly collide in the air as the transmission medium.
Figure 7:
Increase of faults in dependency of the number of probes
(Interval of transmission 1 s)
4 Range of Transmission
As illustrated in figure 7, the fault curve climbs steeply, if a critical number of probes
is reached, as the air, functioning as the transmission medium, is increasingly occupied.
Even with as few as two probes, faults cannot be excluded to 100%.
For this reason, limitation to a maximum number of 16 probes is recommended for
the shortest transmission interval of 1 second, as the fault ratio already strongly increases from 24 probes.
External probes
However, faults can also arise for a small number of probes; they may be caused by
other influences from the environment.
External probes might also use the same frequency. In the event that they operate
without the „Listen before Talk“ function, they arbitrariliy transmit information on the
same frequency without observing the operations and priorities of the other probes.
Hence, if for example a probe transmits its radio telegram, and an external probe is
simultaneously doing the same, the radio telegram will be destroyed. As the probes
are not able to check their own transmission while transmitting, a fault will not be detected.
Electrical equipment
In crude industrial environment radio telegrams can be destroyed for example
through frequency converters, electric welding equipment or insuficiently shielded
PCs, audio-visual equipment, electronic transformers, ballasts, etc. Other components may also generate bursts that are located on the same frequency.
Determination of the maximum number of probes
In the event that for a transmission interval of 1sec a number of more than 16 probes
is to be installed, a longer transmission interval must be set, in order for the fault rate
not to increase further.
Example:
16 probes wiht 1 sec transmission interval Ⳏ 32 probes with 2 sec transmission interval
For an even further increase of the number of probes, the following example illustrates the calculation below.
Example:
16 probes with 1 sec transmission interval Ⳏ 48 probes with 3 sec transmission interval
(theoretically)
From a transmission interval of ≥ 3 sec the telegram will be sent twice. As a consequence, the number of applicable probes is reduced by half.
16 probes with 1 sec transmission interval Ⳏ 24 probes with 3 sec transmission interval
(effectively)
The same phenomenon re-occurs for a transmission interval of ≥ 60 sec. From this
transmission interval, the telegram will be sent three times.
Elimination of Faults
At the receiving end, fault arising through lost telegrams - regardless whether through
external sources of interferrence or through collisions due to a large number of
probes - can be bypassed by means of the parameter „radio-timeout“. The value last
13
4 Range of Transmission
received will then be maintained over 2 … 10 transmission intervals and only then the
alarm radio-timeout will be activated (display „----“).
Through this function short-term faults or interferrences will be bridged and to do not
lead to an error.
NOTE!
For collisions due to too large a number of probes, the factors „number of probes“, „transmission intervals“ and at the receiving end „radio-timeout“ must be observed and modified,
if applicable.

5 Setup-Program
5.1
General remarks on the setup program
This setup program may be used to configure probes and receivers with a PC. The
configuration data can be stored on data carriers and printed out.
Configurable parameters are:
• Probe ID
• Transmission interval
• Transmission frequencies (only at 915 MHz)
The factory settings are:
• Probe ID (continuous)
• Transmission interval 10 s
• Transmission frequency 868.4 MHz or 915.4 MHz
The setup program allows to overwrite modified parameters with the factory setting
at any time.
The connection between the probe and the PC is estabilshed using a PC interface
(USB/TTL or TTL/RS232 converter).

NOTE!
For a transmisison interval of > 10 sec, a so-named link telegram will be transmitted by the
probe, i.e. for a period of 30 minutes, telegrams will be transmitted in the 10 sec interval as
set by the manufacturer, only after this period, telegrams will be sent in the set interval.
NOTE!
As soon as the setup plug is plugged in, the probe automatically transmits telegrams in a
transmission interval of 1 sec, in order for the receiver to immediately recognised the modifications. After disconnecting the setup plug, the telegrams will be sent in the set transmission interval.
Explications
Probe identification (probe-ID)
The probe identification (probe-ID) is an unambiguous number with a maximum of 5
positions, that is recognised by the receiver. The ID can individually be modified, e.g.
in order to obtain a better overview for a machine. However, it must be observed that
one ID is only allocated once within a company, as probes with the same ID cannot
be distinguished by a receiver, even for large distances.
Transmission interval
This parameter defines, in what interval data will be sent to a receiver. The setting of
the parameters „transmission interval“ has an effect on the service life of the battery.
Therefore, the selection should be made with caution and not exclusively in consideration of the transmission quality.
Transmission frequency
The transmission frequency determins the frequency band, in which the data will be
transmitted to a receiver. In Europe, the transmission frequency has been set to
868.4 MHz, as special regulations have been determined for the ISM band (industrialscientific-medical) with regard to transmission interval and transmission power.
In the 915 MHz-frequency band ten frequencies may be configured.
