Wireless temperature online monitoring system

The wireless temperature sensor is used to measure the temperature of the surface or contact of high-voltage live objects, such as the operating temperature of exposed contacts in high-voltage switch cabinets, busbar connections, outdoor switches and transformers. The wireless temperature sensor is composed of a temperature sensor, signal conditioning and amplification, logic control circuit, wireless modulation interface, etc. (as shown in the figure below). The sensor sends the collected temperature signal to the wireless temperature monitor via the wireless network.
