BWR₂-04 (TH) series Transformer winding thermometer is a special instrument designed for transformers by adopting the principle of additional temperature rise. The instrument has good protection performance, can work normally in outdoor conditions, can be widely used in transformers and other equipment temperature detection and control. The instrument is equipped with four to six adjustable control switches, which can be used for transformer cooling system control and signal alarm, over-temperature tripping and so on. Through embedded in the BL-B (TH) transmitter temperature transmitter or Pt100 platinum resistance, output and temperature value corresponding to the DC (4-20) mA current signal or Pt100 platinum resistance signal, for computer systems and secondary instrumentation, to achieve unmanned power station management.
