Important notes
Usage for the intended purpose
The temperature sensor TRG 5-6.. in conjunction with temperature switches TRS 5-50, TRS 5-52 or
with temperature transmitter TRV 5-40 are designed for measuring temperatures in steam or hot water.
Danger
The temperature sensors TRG 5-63 or TRG 5-64 are screwed into vessels or pipes. When
loosening the temperature sensor steam or hot water might escape! This presents the risk
of severe scalding all over the body!
It is therefore essential not to dismantle the temperature sensor unless the boiler pressure
is verified to be 0 bar.
The temperature sensor becomes hot during operation.
Risk of severe burns to hands and arms.
Before carrying out installation and maintenance work make sure that the equipment is cold.
Safety note
Safety temperature limiters/monitors are items of equipment with safety function (PED) and must only be
installed, wired and commissioned by qualified and competent staff.
Retrofitting and maintenance work must only be performed by qualified staff who - through adequate
training - have achieved a recognised level of competence.
The temperature sensors TRG 5-63, TRG 5-65, TRG 5-66 and TRG 5-67 feature one integrated platinum
resistance thermometer Pt 100 to EN 60751 each.
The temperature sensors TRG 5-64 and TRG 5-68 are equipped with two platinum resistance
thermometers Pt 100 for the connection of additional indicating equipment.
The ohmic resistance of the resistance thermometer changes as a function of temperature. If a
constant current is applied, the voltage produced by the change of resistance is measured and further
processed in the temperature switch or temperature transmitter.
The temperature sensor can be used as measuring transducer for
na safety temperature monitor/limiter in conjunction with temperature transmitter TRV 5-40 and
control unit NRS 1-40.1
na temperature monitor/controller in conjunction with temperature transmitter TRV 5-40 and
switching controller TRS 5-40
na safety temperature monitor/limiter in conjunction with temperature switch TRS 5-50
na temperature monitor in conjunction with temperature switch TRS 5-52

permanently immersed in the fluid. Fig. 2 and Fig. 4
nThe seating surfaces of the threaded standpipe or the flange provided on the vessel
must be accurately machined, see Fig. 3.
nDo not completely insulate the temperature sensor. See examples of installation in
vessel Fig. 5 and Fig. 6
nOnly qualified welders certified according to EN 287-1 may weld welding sleeves into
lines or vessels.

or the seven-segment display on the right (TRV 5-40, TRS 5-50)
Error code Error Remedy
E.xxx Temperature sensor defective, temperature
reading too low. Check whether the temperature sensor outputs cor-
rect readings (see Fig. 12). If there are any deviations
please replace the measuring element with a new one.
Check the sensor lines (short circuit, interruption?).
E.xxx Temperature sensor defective, temperature
reading too high.
Measure the fluid temperature
Use table Fig. 12 to ascertain the current temperature of the fluid via the resistance value of the Pt 100.
1. Take cover doff the terminal box .
2. Connect test cable directly to the measuring element e.
3. Use an ohmmeter for measuring the resistance value.
4. Look up the corresponding resistance value in the table, interpolate if necessary and read off the
temperature.
5. After measurement replace cover dand fix it securely in place.

Removing and disposing of the temperature sensor
Removing and disposing of temperature sensor TRG 5-63 or TRG 5-64
1. Disconnect supply voltage (TRV 5-40, TRS 5-50, TRS 5-52).
2. Take cover doff the terminal box .
3. Disconnect the measuring element eand pull line mout of the cable gland.
4. Before removing the equipment make sure that is is neither hot nor under pressure.
For the disposal of the equipment observe the pertinent legal regulations concerning waste disposal.
Danger
The temperature sensors TRG 5-63 or TRG 5-64 are screwed into vessels or pipes. When
loosening the temperature sensor steam or hot water might escape! This presents the risk
of severe scalding all over the body!
It is therefore essential not to dismantle the temperature sensor unless the boiler pressure
is verified to be 0 bar.
The temperature sensor becomes hot during operation.
Risk of severe burns to hands and arms.
Before carrying out installation and maintenance work make sure that the equipment is cold.
If faults occur that are not listed above or cannot be corrected, please contact our service centre or
authorized agency in your country.
