Product Overview:
Our company has developed a product that can timely monitor the temperature of electrical connections, addressing the potential hazards of excessive temperature rise caused by factors such as material aging, poor contact, and overload current. This series of on-line temperature monitoring devices for electrical connections features low power consumption design, wireless temperature measurement technology, and boasts features such as complete isolation, easy installation, strong anti-interference capability, and reliable operation. It effectively solves the problem of temperature measurement under high-voltage conditions.
