Description
GESTRA TRG 5-63, TRG 5-64, TRG 5-65, TRG 5-66, TRG 5-67, TRG 5-68 Temperature Sensor
TRG 5-6.. temperature sensors are used in combination with TRS 5-50 and TRS 5-52 temperature switches or the TRV 5-60 temperature transmitter for measuring the tem- perature in steam and hot water.
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 sen- sors each feature two Pt100 platinum resistance thermom- eters 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 resist- ance is measured in the temperature switch or temperature transmitter, and further processed.
The temperature sensor can be used as a measuring transducer for
- a safety temperature monitor/limiter, in combination with the TRV 5-60 temperature transmitter and URS 60/61 control unit
- a temperature monitor/limiter, in combination with the TRV 5-60 temperature transmitter and URS 60/61 control unit
- a safety temperature monitor/limiter, in combination with the TRS 5-50 temperature switch
- a temperature monitor in combination with the TRS 5-52 temperature switch.
Functional safety as per IEC 61508
Incombination 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 safety- related 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.
