Acrel Wireless Temperature Sensor Application in South Africa

Time: 9 December 2020  |   Source: Acrel

AbstractWith the development power industry,the requirements for the safety and reliability of equipment are getting higher and higher.In this situation,ACREL wireless temperature monitoring system is designed for high voltage device.This technology is to install the temperature sensor with built-in battery or temperature sensor by current sensing and wireless transmitter module at each temperature measurement point. The sensor periodically sends the temperature measurement data wireless to the receiving unit, and the receiving unit can be connected to the network to send the data to the master station, thereby realizing electrical temperature monitoring of a regional system.
