Netvox Wireless 2-Gang Thermocouple Sensor -High Temperature - R718CK2 is used to detect temperature of the object and medium which thermocouple is contacted. It can be connected to two thermocouples for testing. It uses SX1276 wireless communication module.

R718CK2 is connected with type K thermocouple, it supports high temperature operation. The collected data is displayed in the gateway.

Principle of Operation

The thermocouple is processed by the ADS1118 chip ADC for ADC sample conversion, and the ADS1118 communicates with the module via SPI.

 

Example Applications

  • Oven Temperature Measurement
  • High Temperature Thermal System Equipment
