BWY2-803 (TH)Series transformer oil level thermostat is designed using the principle of compound temperature rise. Suitable forFor temperature detection and control of other equipment. The instrument has good protection performance, can be in outdoor conditionsNormal operation, the instrument is equipped with three sets of adjustable control switches, which can be used for transformer cooling system startup, signaling, and other functions.No. Alarm. At the same time can output the temperature value corresponding to (4-20)mA Current signal and Pt100 platinum resistance signals. For use in computer systems and secondary instrumentation.
Working Principle
BWY2-803 (TH)Series transformer oil level temperature controller, mainly consists of elastic element, sensing conduit, sense ofTemperature parts, temperature transmitter, digital temperature display meter composition. It consists of elastic element, sensing conduit and temperature sensing part.The sealing system composed of parts is filled with temperature-sensitive medium, when the measured temperature changes, the temperature-sensitive parts of the temperature-sensitive mediumThis volume increment is transmitted through the sensing conduit to the elastic element in the meter, which produces a A corresponding displacement, which is amplified by the mechanism to indicate the measured temperature and actuate the microswitch. Outputs on and off control signals to drive the cooling system for the purpose of controlling the temperature rise of the transformer. By embedded in the Temperature transmitter within the composite sensor, output (4-20)mA Standard current signals, input to computer system. Realization of unmanned power station management.

Installation and use
The meter must be placed vertically during operation.
Insert the digital temperature display into the opening in the console and push it in gently and firmly.
Warm package installation
Before installing the temperature package, the transformer mounting hole should be filled with transformer oil, and then the temperature package should be inserted slowly and the M27×2 mounting connector should be tightened to ensure that the temperature package is completely submerged by the oil.
The hose between the temperature package and the meter head must be fixed accordingly, and the distance between them is 300mm, and the bending radius must not be smaller than R100mm. The bending radius shall not be less than R100mm, and the excess hose shall be coiled into a circle with a diameter larger than Φ200mm and fixed on the transformer body.
Switch setting: can be set arbitrarily within the full range according to the user's needs.
