Undertake OEM/ODM services for OEM and OEM processing
The unit is designed for power applications and is ideal for hot spot temperature measurement of transformer windings for A new type of transformer internal temperature monitoring device that directly, real time, and accurately measures the temperature of hot spots such as windings can realize comprehensive monitoring of the inside of the transformer. In addition to having a wide temperature measurement range and accurate and reliable temperature measurement performance, it also has excellent anti-EMI/RFI (electromagnetic interference/radio frequency interference) characteristics, high-voltage insulation and anti-interference and other excellent performance.
Real-time and accurate monitoring of "hot spot" temperature during dynamic load operation can be realized. It solves the problems of low safety, poor measurement accuracy and failure of temperature measurement using traditional electrical temperature measuring instruments in the electromagnetic environment.
