BWY-804 / BWY-806 Transformer Oil Surface Temperature Controller Type 1
The BWY-804 / BWY-806 Transformer Oil Surface Temperature Controller Type 1 is designed for oil temperature detection, local indication, alarm and control of transformers and other electrical equipment. Based on the composite temperature rise principle, the product provides reliable outdoor protection performance and supports multiple output options, including 4-20mA remote output and Pt100 signal output. It is widely used for transformer cooling system control, over-temperature alarm and remote monitoring in oil-immersed transformers, substations, power distribution systems and industrial electrical equipment.
