The Transformer Digital Top-Oil Temperature Controller is a sophisticated device designed to monitor and control the temperature of transformer oil. This controller primarily comprises a mechanical component and a digital sensing unit. The sealed system, which includes elastic elements, sensing conduits, and temperature sensing components, is filled with a temperature sensing medium. When the surrounding temperature changes, the volume of this medium shifts, transmitting the change through the sensing conduit to the elastic element within the instrument, resulting in a corresponding displacement. This displacement is amplified by the mechanism, allowing for accurate temperature indication and enabling the micro switch to produce a control signal that operates the cooling system, effectively regulating transformer temperature, Manufactured in China, this top-of-the-line device employs advanced composite sensing technology, converting the signal from the Pt100 platinum resistance sensor located in the temperature pack into an RS485 digital signal for transmission to the control room terminal. The controller is capable of storing up to 10,000 monitoring data points and operating status information, which can be easily exported. It features remote data transmission capabilities, alarm outputs, control signals, and local indication functions to manage communication abnormalities and conduct self-checking for faults, This innovative controller can display and control both top oil temperature and winding temperature simultaneously. It offers essential advantages, including electrical isolation for communication, easy installation, robust anti-interference capabilities, and remote configuration options. These features enable effective remote online monitoring of power transformer oil temperature. As a leading supplier and factory in the industry, our Transformer Digital Top-Oil Temperature Controller is the ideal choice for ensuring the optimal performance and longevity of your transformer systems.
