m-l

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.

Merkmale

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
Available with Pt100 (Platinum 100Ω) resistance output
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

Optionen

Supplies 24 VDC for AKM winding temperature simulation systems
Das Analoge Messgerät ermöglicht eine genaue und einfache Temperaturanzeige auf einen Blick
Display features large, highly visible, bright red LEDs
Wandelt ein Pt100-Signal in ein 4-20-mA-Signal um, das mit Fernanzeigen oder dem Anschluss an ein SCADA-System verwendet werden kann

Applications

For winding temperature simulation where the point of measurement (the well or pocket) is not easily viewed from the base of the apparatus or the information is required remotely.
