Power Plant Transformer Oil Level Thermostat BWY-804AJ(TH) Thermometer Details.
BWY-804AJ(TH) series transformer oil level thermostat is a transformer special instrument designed by the principle of compound temperature rise. It is suitable for temperature detection and control of transformers and other equipment. The instrument has good protection performance, can work normally under outdoor conditions, the instrument is equipped with four to six groups of adjustable control switches, which can be used for transformer cooling system control and signal alarm, over-temperature tripping, etc. Through the temperature transmitter or PT100 platinum resistance embedded in the primary meter, the DC(4-20)mA current signal or PT100 platinum resistance signal corresponding to the temperature value can be output, which can be used by computer systems and secondary instruments to realize the management of unmanned power stations.
BWY-804A(TH) can output a PT100 platinum resistance signal; AA(TH) type can output two PT100 platinum resistance signals;
BWY-804AA(TH) can output two PT100 platinum resistance signals;
BWY-804J(TH) can output one (4 20) mA current signal; JJ(TH) type can output two (4 20) mA current signals;
BWY-804JJ(TH) can output two (4 20) mA current signals;
BWY-804AJ(TH) type simultaneously outputs a PT100 platinum resistance signal and a (4 20) mA current signal.
