BWR-04J(TH) Thermometer

 

BWR model thermostats include the following common models:

BWR-04 Series

  • BWR-04: Basic winding thermostat with additional temperature rise principle, measuring the transformer winding temperature by means of a current transformer.
  • BWR-04J(TH): With the function of temperature transmitter, it can output DC(4-20)mA current signal.
  • BWR-04A(TH): Outputs a Pt100 platinum resistance signal.
  • BWR-04AJ(TH): Simultaneous output of a Pt100 platinum resistance signal and a DC (4-20) mA current signal.
  • BWR-04JJ(TH): Outputs dual DC (4-20) mA current signals.

BWR-06 Series

  • BWR-06: Typically used where a wider temperature range or higher accuracy measurement is required.

BWR-4 Series

  • BWR-4: Basic winding thermostat with 4 optional control switches and capillary tube length of 6 meters.
  • BWR-4L9S8: With 6 control switches, a capillary tube length of 9 meters, an aviation plug outlet and a switching cable length of 8 meters.

BWR2 Series

  • BWR2-04A(TH): Outputs a Pt100 platinum resistance signal.
  • BWR2-04AA(TH): Outputs two Pt100 platinum resistance signals.
  • BWR2-04AJ(TH): Simultaneous output of a Pt100 platinum resistance signal and a DC (4-20) mA current signal.
  • BWR2-04J(TH): Output DC (4-20) mA current signal.
  • BWR2-04JJ(TH): Outputs dual DC (4-20) mA current signals.
These types of thermostats are widely used in the measurement and control of winding temperatures of oil-immersed power transformers and can meet different measurement requirements and installation conditions.
