HCWJ Low Voltage Switch Contact Temperature Measuring Device

PRODUCT PREVIEW

The device is suitable for low-voltage (22v or 380v) substation and distribution system,which is used to measure the temperature of cable joints,circuit breaker wiring lead ends,bus bars,etc,in real time .Six sensors are standard and can measure temperature at six measuring points.The user only needs to stick the temperature sensing surface of the sensor(with a black arc) on the element to be measured,and then bind it with high-temperature tape,and the other end of the sensor is connected to the sensor socker of the temperature measuring device.

The temperature measured by either sensor is higher than the set value,and relay J1 acts to send out an alarm signal that the temperature is too high,if any sensor is open,NULL,relay J2 action,and a sensor disconnection alarm signal is issured.HCWJ-6/port six-point wired temperature measuring device has 2 switching inputs,which can be connected to 2 passive contacts.HCWJ-6 /port six-point wired temperature measuring device has RS485 communication protocol and can transmit measurement data remotely in real time.
