The XMT-1225 series digital temperature controller is a supporting product specially designed by our factory for power transformers. It is connected with BWY (WTYK) -802/803ATH, WTYK-04, BWY-804AJ (TH) temperature controllers to achieve remote sensing and control of power transformer oil temperature. The XMT-1225 model can output 4-20mADC standard signals.
