KC700 Wireless Temperature Monitoring For Low Medium Switchgear

The wireless contact temperature measuring device installs the temperature measuring sensor on the electrified contact in the switch cabinet, and uploads the temperature data to the receiving end by wireless transmission, and the receiving terminal displays the temperature data through the liquid crystal, and uploads the temperature data to the customer through the RS485 bus. backend software. When the abnormal temperature of the contact is detected, the system can automatically and remotely alarm, so as to eliminate the hidden danger in time.
