Acrel Wireless Temperature Sensor Application in South Africa

Keywords:Wireless temperature sensor,wireless temperature monitoring system,470Mhz wireless temperature sensor

1.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.

2.Wireless temperature monitoring device 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.
