System description

The TRG 5-6x are temperature sensors with integrated platinum resistance thermometers Pt 100 to

EN 60751. The temperatures sensed by the temperature sensor are converted by the temperature trans-

mitter TRV 5-40 and provided as a data telegram on the CAN bus.

The CANopen protocol is used for the data transfer via CAN bus.

The temperature sensor can be used as a measuring sensor for

■

a safety temperature control monitor/limiter in conjunction with temperature transmitter TRV 5-40 and

the switching controller NRS 1-40.1 and

■

as sensor for a temperature limiter/controller in conjunction with temperature transmitter TRV 5-40 and

the control unit TRS 5-40.

The equipment combinations can be used as controls, monitors or limiters in steam boilers and (pressu-

rised) hot water installations to TRD and EN 12952 and EN 12953.

Function

The temperature sensors TRG 5-63, TRG 5-65, TRG 5-66 and TRG 5-67 feature one integrated platinum

resistance thermometer Pt 100 each.

The temperature sensors TRG 5-64 and TRG 5-68 are equipped with two platinum resistance thermome-

ters Pt 100 for the connection of additional indicating equipment.

The resistance value of these thermometers changes as a defined function of the temperature.

The resistance thermometer is supplied with a constant current by the temperature transmitter and the

voltage generated by the changing of the resistance value is measured and processed in the transmitter.
