Introduction: The temperature indication controller is mainly composed of elastic elements (bellows), capillary and warm package. The three-part sealing system is filled with temperature-sensitive liquid. When the measured temperature changes, the volume of the temperature-sensitive liquid in the temperature package changes, and the volume is transferred through the capillary to the elastic element (bellows) To produce a corresponding displacement. This displacement can be indicated by the body after the amplification of the measured temperature and drive the micro switch, the output signal to drive the cooling system to achieve the purpose of controlling the temperature rise of the transformer. BWY-803A temperature indicator controller, the use of composite sensor technology, which is based on large-scale transformer user requirements, to ensure that more than 8000kVA large power transformer operation reliability, security design, the product embedded in the package Pt100 platinum resistance Features: 1, the instrument uses full-liquid filling, linear dial, to improve the instrument before the scale of one-third of the indication accuracy, extended the instrument measuring range (0 ~ 120 ℃) 2, the switch can be 0 ~ 120 ℃ in the full range of arbitrary settings, set the knob can be rotated. 3, temperature package embedded platinum resistance, with XMT digital instrumentation, long-distance instructions to the top of the transformer oil temperature. 4, with a high temperature indicator can record the measured object has reached the *** high temperature.
