Abstract: As the power industry advances, there is an increasing demand for enhanced safety and reliability of equipment. In response to this scenario, the ACREL wireless temperature monitoring system has been engineered specifically for high-voltage apparatus. This system incorporates temperature sensors, which are either self-powered or utilize current sensing, along with wireless transmitter modules, at each designated temperature measurement location.
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.
Keywords: Wireless temperature sensor; wireless temperature monitoring system; 470Mhz wireless temperature sensor.
Project Overview
