Micro Passive Wireless Temperature Sensor HYJT-W V2.0
With the continuous advancement of modern power electronics technology, induction power extraction technology has matured. Compared to traditional onl
Product details
HYJT-W V2.0Suitable for real-time temperature monitoring of various electrical equipment contact points, mainly targeting electrical contacts inside switchgear, such as busbars and circuit breakers/Tailored temperature measuring devices for static contacts, transformer inlet and outlet contacts, cable joints, outdoor devices such as knife switches, circuit breakers, transformer inlet and outlet contacts, etc., are designed to address issues such as excessive temperature rise caused by material aging, poor contact, and current overload. When the temperature exceeds the preset alarm value, they can promptly sound an alarm and notify operation and maintenance personnel to handle it, reducing equipment losses.
The location should be infinitely close to the hotspot; The longer the distance, the greater the impact of the environment, and the lower the accuracy.
