Turck's combined air humidity/temperature sensor offers efficient condition monitoring

Condition Monitoring Sensor for Temperature and Air Humidity

The combined temperature air humidity sensor for condition monitoring in IIoT and sensor-to-cloud applications

Turck is offering its first combined air humidity/temperature sensor for cost-effective condition monitoring in the field or in IIoT applications; very easy to integrate thanks to the IO-Link interface. The combination of the two measured variables air humidity and temperature in a single device makes the CMTH-M12 ideal for use in the condition monitoring systems of machines and plants or for monitoring the climatic conditions in production halls and warehouses in a wide range of sectors – from the automobile industry to the semiconductor and food industry, right through to  agriculture.

Your Benefits

  • Consistent quality assurance by monitoring important ambient variables    
  • Cost-effective through the integration of two measured variables in a single device
  • Easy retrofitting of condition monitoring in conjunction with autonomous control components in IP67

IO-Link for easy configuration

The sensor transfers temperature and air humidity as a continuous process value via the cyclical IO-Link process data. Two limit values ranges, each with a minimum and maximum value, are also provided. A warning signal can be output for these in the event of an out-of-range value. The bidirectional IO-Link interface can also be used for the transfer of cyclical user data as well as warning and status messages, such as operating hours. Conventional switching outputs are also provided as an alternative. 

Decentralized condition monitoring solutions

When used in combination with Turck's multiprotocol I/O devices, user data and analysis data can be transferred over separate Ethernet protocols. While I/O modules transfer the user data to a higher-level controller via Ethernet/IP or Profinet, Modbus/TCP can be used as a parallel channel for analysis data. This information can also be provided for mobile access worldwide via Turck's edge gateways and cloud systems.
