BWY -803/804 (TH) Series  Transformer Oil Level Thermostat

WY-804 port (TH) series transformer oil level thermostat is a transformer special
instrument designed by using the principle of composite temperature rise, suitable
for temperature measurement and control of transformer and other equipment. The
instrument has a good protection performance, can work normally under outdoor
conditions. The instrument is equipped with four to six groups of adjustable control
switches, can be used for transformer cooling system control and signal alarm,
overtemperature tripping, etc. Through a temperature transmitter or Pt100 platinum
resistor embedded in primary meter, the DC(4-20)mA current signal or Pt100 platinum
resistance signal corresponding to the temperature value can be output for the use
of computer system and secondary instrument in order to achieve power station
unmanned management.
