BWR-04□(TH) series transformer winding thermometer
- Details
BWY-04□ (TH) series transformer oil temperature controller is a transformer-specific instrument designed using the principle of compound temperature rise. Applicable to transformer and other equipment temperature detection and control. The instrument has and good protection performance, can work normally in outdoor conditions, the instrument is equipped with four to six adjustable control switches, can be used for transformer cooling system control and signal alarm, over-temperature tripping. Through embedded in the primary table temperature transmitter or Pt100 platinum resistance, can output and temperature value corresponding to the DC (4-20) mA current signal or Pt100 platinum resistance signal, for the computer system and the use of the secondary instrumentation, to achieve unmanned power station management.
