RTD Oil & Winding transmitters

 




 

  • Pt100 RTD based Oil & Winding Temperature Transmitters
  • Ideal for SCADA systems
  • With 4-20mA dc output and Optional digital indicator
  • In various configurations for all applications
  • Single, Dual (even 4) output versions
  • 1,2 or 3 measuring systems for all windings in transformer
  • OTM 1.1/* refers to Oil Temperature Transmitters with Single output & 1 system
  • OTM 1.2/* refers to Oil Temperature Transmitters with Single output & 2 systems
  • OTM 1.3/* refers to Oil Temperature Transmitters with Single output & 3 systems
  • OTM 2.1/* refers to Oil Temperature Transmitters with Dual output & 1 system
  • OTM 2.2/* refers to Oil Temperature Transmitters with Dual output & 2 systems
  • OTM 2.3/* refers to Oil Temperature Transmitters with Dual output &  3 systems
  • WTM 1.1/* refers to Winding Temperature Transmitters with Single output & 1 system
  • WTM 1.2/* refers to Winding Temperature Transmitters with Single output & 2 systems
  • WTM 1.3/* refers to Winding Temperature Transmitters with Single output & 3 systems
  • WTM 2.1/* refers to Winding Temperature Transmitters with Dual output & 1 system
  • WTM 2.2/* refers to Winding Temperature Transmitters with Dual output & 2 systems
  • WTM 2.3/* refers to Winding Temperature Transmitters with Dual output &  3 systems
  • Comprises of a Pt100 RTD sensor for Oil temperature measurement
  • Winding Temperature is measured using a special Thermal Imaging device which is specially designed for each transformer manufacturer
  • A Thermal Imaging Device accurately simulates the winding gradient above top oil temperature based on CT secondary current
  • Since the time constant of the thermal imaging device is same as oil immersed transformer winding, the winding temperature is accurately tracked with respect to time.
  • The resistance output from Pt100 sensor is converted to standard 4-20mA dc current output in RCXT unit
  • Apart from 4-20mA dc current output, these units can be provided additionally with
    • MODBUS
    • CANOPEN
    • PROFIBUS
    • Ethernet
    • USB or other digital communications
    • GSM/GPRS Wireless communications options can also be provided for remote monitoring
  • All in DIN Rail mounted housings with CE certification
  • RTU, Webserver, Datalogger, PLC configurations can also be provided in DIN Rail housings
  • Digital Indicator can be provided also.
