BWR2-04AJ (TH) Transformer Winding Temperature Controller

The BWR2-04 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 and signal alarm, over temperature tripping, etc. as needed. By embedding a temperature transmitter or Pt100 platinum resistor in the BL-B (TH) transmitter, 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 station management.
