(PROJECTS)ACREL Wireless Temperature Sensor Applic

Abstract:With 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.
Keywords: Wireless temperature sensor; wireless temperature monitoring system; 470Mhz wireless temperature sensor.
 
Project Overview
Chauvin is located in ANTONY Cedex,France. the project is mainly used in substation in the substation in South Africa. The related products models are 2 PCS ATC450-C, dozens of wireless temperature sensors including model ATE400 and ATE100.
 
Project Introduction
Acrel on-line temperature measurement device is suitable for the temperature detection of high and low voltage switches, circuit breaker contacts, high voltage cable middle heads, low voltage and high current equipment, to prevent contact caused by oxidation, loosening and other factors during operation Excessive contact resistance and heat generation become a safety hazard, timely, continuous and accurate reflection of equipment operating status, and equipment safety.
