BWY-804(806) oil level thermostat

Transformer oil surface temperature controller BWY-804 seriessummarize

Transformer oil level thermostat is a transformer instrument designed using the principle of compound temperature rise. It is suitable for temperature detection and control of transformer and other equipments. The instrument has 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 trip, etc.. Through the temperature transmitter or Pt100 platinum resistance embedded in the primary table, it can output DC (4-20) mA current signal or Pt100 platinum resistance signal corresponding to the temperature value, which can be used by the computer system and the secondary instrument to realize the management of unmanned power station.
