Online Temperature Monitoring Technical Features

Thorough Isolation, Safe and Reliable

The online temperature monitoring system transmits temperature data wirelessly, featuring thorough isolation, safety and reliability, and strong anti-interference capability. It is particularly suitable for online temperature monitoring at high-voltage, high-current contact points.

High Accuracy and Reliability

Temperature-measuring elements adopt thermocouples or digital temperature sensors, and small-signal processing uses the latest zero-drift operational amplifiers to ensure temperature measurement accuracy. The system is strictly designed in accordance with the GB/T 17626 Level 4 standard and has test reports from relevant authorities.

Diverse Power Supply Methods, Flexible Networking Options

Temperature sensors can be powered by high-performance imported lithium batteries or by online current induction. The system supports various communication interfaces including RS485, wireless, fiber optic, Ethernet, and GSM, enabling system networking for different field conditions.

Working Principle of Wireless Temperature Sensors

Wireless temperature sensors are used to measure the temperature at high-voltage electrical contact points, such as exposed contacts in high-voltage switchgear, busbar connections, cable heads, circuit breaker contacts, and transformers. The wireless temperature sensor consists of a wireless transmitting circuit, CPU logic control circuit, signal conditioning and amplification circuit, temperature sensor, and other components.
