The ZBWY-804 series transformer oil level thermometer is used to measure the oil level temperature of power transformers. This thermometer adopts an electromechanical integration design, using a metal bellows as the temperature sensing element. In addition to measuring transformer oil temperature, it is equipped with four micro switches to drive the transformer cooling system to control the temperature rise of the transformer, and can output alarm, trip, and other signals according to the set values. The ZBWY-804 series oil thermometer can output PT100 or 4~20mA signals, which can be connected to secondary instruments and computer monitoring systems for remote monitoring of transformer oil temperature.
