BWR-04JJ (TH) Transformer Winding Temperature Controller Introduction: The BWR-04 port (TH) series transformer winding temperature controller is a transformer specific instrument designed using the principle of additional temperature rise. This instrument has good protective performance and can work normally under outdoor conditions. It can be widely used for temperature detection and control of transformers and other equipment; The instrument is equipped with four to six sets of adjustable control switches, which can be used for transformer cooling system control, signal alarm, overtemperature trip, etc. as needed. By using a temperature transmitter or Pt100 platinum resistor embedded in the primary meter, a DC (4-20) mA current signal or Pt100 platinum resistor signal corresponding to the temperature value is output for use in computer systems and secondary instruments, achieving unmanned power plant management. Technical parameters of BWR-04JJ (TH): Output signal: dual DC (4-20) mA standard current signal. Working conditions: ambient temperature (-40~+55) ℃, relative humidity ≤ 95%. Measurement range: (0-150) ℃. Accuracy: Level 2.0 (maximum allowable error of detection point is ± 3 ℃).
