Passive Wireless Temperature Measurement Sensor

Main functions

Function Introduction

Temperature detection function

Real-time detection of the current temperature of the measured part

Power supply voltage self-test function

Real-time detection of the sensor's own power supply voltage value

Power is drawn from induced current

The sensor is powered by electromagnetic induction of primary side current.

Note: All data detected by the sensors are uploaded to the wireless temperature measurement host via wireless transmission.

Install

Part

Removable high-voltage switchgear: busbars, stationary contacts, cable connections, etc.

Low-voltage switchgear: outgoing terminals, circuit breaker input and output terminals.

Tubular busbars, copper busbars, substation terminals, etc.

Fixed high-voltage switchgear: busbars, isolating switches, cable connections, etc.

Low-voltage switchgear: circuit breaker inlet, outlet, cable outlet, etc.

Installation steps

Step 1: Estimate the length of the installation location and insert the appropriate length through the module; insert the power-collecting plate and soft silicone into the sensor (with the corrugated side of the soft silicone facing down, aligned with the temperature sensing position).

Step 2: Wrap the module around the power source (main current path) so that the temperature measuring point contacts the part to be measured, and tighten the alloy plates on both sides; then overlap the two ends under the clips. Tighten the screws with an Allen wrench.
