Premium Bimetallic Thermometer for Transformer Monitoring
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.

The core working principle of the WTZK-02/03 Series hinges on the bimetallic technology, a pioneering approach that utilizes two dissimilar metals bonded together. These metals expand at different rates when exposed to heat, enabling precise temperature readings. This mechanism is especially beneficial in the measurement of transformer oil, air, and steam temperatures. The accuracy of this technology ensures that the transformers operate within their optimal temperature range, thereby enhancing their efficiency and preventing potential damage due to overheating. Moreover, the application of the WTZK-02/03 Series extends beyond just transformer temperature monitoring. Its versatility allows it to be employed in a variety of settings where accurate temperature readings of liquids and gases are requisite. The robust design ensures durability and long-term reliability, making it an indispensable tool in industries such as power generation, manufacturing, and HVAC systems. With the WTZK-02/03 Series Transformer Temperature Controller, Guanshan leads the way in providing solutions that meet the rigorous demands of modern industrial applications, all centered around the pivotal technology of the bimetallic thermometer.
