Premier Air Pressure Gauge - WTZK-02 by Guanshan

Working principal & Application

WTZK-02/03 Series Transformer Temperature Controller (BWY-02/03 Series Transformer Temperature Controller), be applicable to measure the temperature of transformer oil or other liquid, airs and steam. And when the temperature that measured is reached or exceeded the initial value it will send out the contact-point signal. It is suitable for taking measurement and control of oil temperature in transformer that over 500KVA. The temperature controller is consist of temperature bulb(the temperature detector), capillary tube and elastic component. Inside the 3 parts of the temperature controller is filling with temperature-sensing medium as a sealed system. When the measured temperature changes the volume of actuating medium in the temperature bulb will be changed along with linear graduation. This volume increment is transmitted by capillary tube to take a corresponding linear displacement. After magnifying the linear displacement by a special amplifier, the measured temperature can be indicated and switch on a micro switch to send out a signal.
