1、 Scope of application








Bwd-3k electronic temperature controller for transformer is an intelligent instrument composed of microprocessor. The platinum resistance of PTl00 is used as the temperature sensor. The platinum resistance is put into the winding of transformer. When the temperature of transformer changes, the resistance of platinum resistance changes synchronously with the temperature. The temperature controller can control the set temperature value. It can start and stop the cooling fan, send out fault alarm, over temperature alarm, control over temperature trip, etc. to protect the transformer.




2、 Compliance with standards




This instrument is specially designed according to JB / r7631-2005 "electronic temperature controller for transformer"




Design and manufacture.
