Resistance thermometer (RTD) with built-in heating element to simulate the measuring of winding temperatures within a transformer. Provides an analog (Pt100) output for remote indication and monitoring. Choice of one or two RTD’s allows for an extra signal for indication or input to SCADA system. Installed in a well (pocket) that allows exchanging units without draining the transformer tank.
Features
Integrated heating element enables accurate simulation of the average or hot spot temperature of the transformer winding
By disconnecting the heating element, the thermometer can directly measure the oil temperature
RTDs enable accurate measurements across an extremely large temperature range
Compact remote indication and monitoring
RTD output allows for temperature indication where it is most convenient
Choose between one or two RTD’s within the same transmitter in either PT100 (100O platinum) or CU10 (10O copper) resistance outputs
Units with 4-20 mA output can transmit signals over long distances
Weatherproof design and robust materials for long trouble-free life
Ventilated case is weatherproof according to DIN 40050 IP54 (NEMA 3S)
Die-cast aluminum case with thermosetting powder coat provides excellent protection in harsh environments
Options
Supplies 24 VDC for AKM winding temperature simulation systems
Analog gauge allows for accurate and easy temperature indication at a glance
Display features large, highly visible, bright red LEDs
Converts a Pt100 to a 4-20 mA signal for use with remote indicators or connecting to a SCADA system
