BWR-4 series winding temperature controller adopts "thermal simulation" technology to measure the temperature of transformer winding, and through the composite transmitter within the PT100 uranium resistance signal is transmitted to the control room of the secondary instrument, which can synchronously display and control the winding temperature of the transformer. Products use a new generation of "multi-turn spring tube" as the driving element, the instrument greatly improves the temperature measurement accuracy and service life. All stainless steel material gram body can effectively protect the internal components from environmental impact and dirt invasion.
