 BWY (WTYK) —803, 802 series pressure type temperature indicator controller (hereinafter referred to as temperature controller) is mainly designed for measuring and controlling the oil temperature of large power transformers, and it is also used for temperature detection and control of other equipment.
This series thermostat has good protection performance and can work normally for a long time under outdoor conditions. There are two or three sets of large-capacity temperature control switches inside the instrument, which can be used for the startup, shutdown and signal alarm of the transformer cooling system, meanwhile, the temperature signal can be transmitted to the control center remotely, and the transformer oil temperature can be displayed synchronously.
