RTD scheme

The Scheme consists of one or more PT-100 Sensors, Current converter Units with built in power supply, optional remote indicator and optional selector switch. The scheme is designed to indicate the Top Oil Temperature / Winding Temperature of the oil-immersed transformers in the control room. With the availability of 4-20 mA DC signal output, the system can be used to integrate OTI and WTI readings to scada systems.
