CHINA MADE TEMPERATURE TRANSFORMER WINDING THERMOMETER BWR-04JJ(TH)

DESCRIPTION

The temperature controller BWR-04JJ (TH) is suitable for temperature detection and control of transformers and other equipment. This instrument has good protective performance and can work normally under outdoor conditions. It is equipped with four to six sets of adjustable control switches, which can be used for cooling system control, signal alarm, overtemperature trip, etc. of transformers. Through temperature transmitters or Pt100 platinum resistors embedded in the primary meter, DC (4-20) mA current signals or Pt100 platinum resistance signals corresponding to temperature values can be output for use in computer systems and secondary instruments, achieving unmanned power plant management.
