Wireless brake pad temperature transmission module

image.jpeg

The wireless brake pad temperature transmission module is a device that can detect the temperature of the brake pads in real time. The device is divided into a transmitter and a receiver. The transmitter detects the temperature of the brake pads in real time through a 4-channel/wheel thermocouple, transmits the temperature wirelessly to the receiver, and the receiver outputs the temperature through the CAN protocol. The equipment has the advantages of high precision, small error, high real-time performance and wide measurement range.


Features:

1. 16-channel multi-type thermocouple input, support various types of thermocouple selection;

2. The accuracy error is 0.5℃;

3. The thermocouple input terminal provides ±45KV overvoltage protection;

4. Each channel has internal cold junction compensation;

5. The temperature of the detection point is sent to the receiving end wirelessly, and the CAN message is output.
