BWR-04W series winding temperature controller adopts "thermal simulation" technology to measure the temperature of transformer winding, and through the meter head PT100 platinum resistance signal or current signal is transmitted to the secondary instrument in the control room, which can synchronously display and control the winding temperature of the transformer. The product uses a new generation of "multi-turn spring tube" as the driving original, the instrument greatly improves the measurement accuracy and service life, and at the same time reduces the volume of the temperature package, convenient for users to install.
