The ZBWY-803 series transformer oil level thermometer is used to measure the oil level temperature of power/distribution transformers. It can be configured with 2 to 3 micro switches as needed to drive the cooling system to control the temperature rise of the transformer, and can output alarm, trip, and other signals based on set values. The ZBWY-803 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.
