Hangzhou Huali transformer temperature controller BWY-803ATH BWY-802ATH Temperature indicator Item NO.: 1942147

1、 Use

Bwy (wtyk) - 803 and 802 series pressure temperature indicating controllers (hereinafter referred to as temperature controllers) are mainly designed for measuring and controlling the oil temperature of large power transformers. At the same time, they are also used for temperature detection and control of other equipment.

This series of thermostat has good protection performance and can work normally for a long time under outdoor conditions. Two or three groups of high-capacity temperature control switches are installed inside the instrument, which can be used for starting, closing and signal alarm of transformer cooling system respectively. At the same time, the temperature signal can be transmitted to the control center remotely to display the transformer oil temperature synchronously.
