Function Each TRG 5-63, TRG 5-65, TRG 5-66 and TRG 5-67 temperature sensor has a Pt100 platinum resistance thermometer.
On the other hand, TRG 5-64 and TRG 5-68 temperature sensors each feature two Pt100 platinum resistance thermometers for the connection of additional indicating equipment.
The ohmic resistance of the resistance thermometer changes as a function of the temperature. When supplied with a constant
current, the voltage produced due to the change of resistance is measured in the temperature switch or temperature
transmitter, and further processed.

The temperature sensor can be used as a measuring transducer for n a safety temperature monitor/limiter, in combination
with the TRV 5-60 temperature transmitter and
URS 60/61 control unit n a temperature monitor/limiter, in combination with the
TRV 5-60 temperature transmitter and URS 60/61 control unit n a safety temperature monitor/limiter, in combination
with the TRS 5-50 temperature switch n a temperature monitor in combination with the
TRS 5-52 temperature switch.
Functional safety as per IEC 61508 In combination with the TRG 5-6 .. temperature sensors, the
TRS 5-50 temperature switch and TRV 5-60 temperature transmitter (with URS 60/61 control unit) are certified to IEC
61508. This standard describes the functional safety of electrical, electronic and programmable electronic safetyrelated systems.
The TRG 5-6.. + TRS 5-50 combination produces a Type B subsystem with safety integrity level (SIL) 3.
The TRG 5-6.. + TRV 5-60 combination (with URS 60/61) produces a Type B subsystem with safety integrity (SIL) 3.
Use in potentially explosive atmospheres Do not use the equipment in potentially explosive atmospheres.
