Wireless temperature measurement system

Introduction to wireless temperature measurement system parameters and functions:
(Below is an introduction to the functions of the wireless temperature measurement section. Please contact us for detailed information.)

Data collection and display functions of monitoring points:

Effectively monitor the temperature of each contact point during the operation of the switchgear, collect and display temperature data of each contact point.

Threshold setting and over limit alarm: The temperature threshold of the measured point can be set. When the temperature measurement point exceeds the over limit value, an alarm indicator light will be output, and relevant contacts will be output. This can be used to connect the switch mode to the substation automation system, or to trigger other types of alarm alarms on site.

Data storage and upload: This host can store on-site data to the computer backend through RS485 communication for centralized display and management by the backend system.

Features of wireless temperature measurement device:

Wireless transmission

Ensure complete electrical isolation between the temperature measurement point and the receiver to ensure electrical safety in high voltage environments.

Communication anti-collision technology

The unique wireless coding anti-collision mechanism greatly increases reliability during communication. Super strong power anti-interference ability, ultra-low power wireless transmission mode, saving 1.5-2 times more power than ordinary carrier coding methods.

Node maintenance free
The temperature sensor adopts advanced low-power and micro power consumption technology internally, ensuring a long battery life and reliable power supply during maintenance cycles.

man-machine interface
LCD display facilitates user data exchange.

Over temperature warning and alarm

Relevant warning and alarm thresholds can be set according to actual needs

Online real-time monitoring
Automatically monitor temperature changes at relevant key points online and upload the measured temperature data to the computer backend.

Easy to install and use

The temperature sensor unit has a small volume, is easy to install, and has fast installation efficiency.
