产品描述

Commodity name: OM.R942 Switchgear Wireless Temperature Measurement Online Monitoring System

Product Overview
The OM.R942 switchgear wireless temperature monitoring system uses sensors to collect temperature data, enabling effective real-time monitoring of switchgear temperatures. Additionally, through data acquisition and analysis, the system provides managers with comprehensive temperature insights, helping them better understand the thermal conditions of equipment operation—and ultimately serving as a valuable reference for equipment inspection and maintenance.

Key Advantages
● The temperature sensor uses a new type of soft magnetic tape for inductive power harvesting, featuring low power consumption and maintenance-free operation.
● Wireless technology is used to transmit signals between the sensor and the wireless temperature measurement and data acquisition device. The acquisition device communicates via RS-485 or IEC61850 communication ports, sending data to backend user software or third-party information integration systems.
● The temperature monitoring backend system can communicate with 255 temperature acquisition module units, offering features such as setting temperature alarm thresholds, monitoring for temperature anomalies, and querying historical temperature data.
