Magnetic field/temperature sensor with IO-Link

The condition monitoring sensor CMMT from Turck detects magnetic field changes on three axes, opening up new areas of application.

The CMMT 3-axis magnetic field/temperature sensor with IO-Link is the third sensor type that Turck has developed specifically for easy-to-use and retrofittable condition monitoring applications. It complements the existing range consisting of the CMVT vibration/temperature sensor and the CMTH for moisture and temperature measurements. The combined measurement of magnetic field and temperature with the CMMT enables easy detection of faults on motors or in processes with magnetic components. The new sensor also enables applications that were previously impossible, such as the non-contact detection of rotation and movement of metal objects without visual contact.

Thanks to its high sensitivity of five microtesla, the sensor also detects the earth's magnetic field, but can hide it if desired by setting parameters. The device transmits the measured values individually or as a vector sum via IO-Link. Users can also assign two independent switching outputs. The CMMT supports the Smart Sensor Profile 4.1.4.

When commissioning the CMMT, users are supported by the Turck Automation Suite (TAS) Magnetic Field Monitor app. This application visualizes sensor data live in the Web browser and can be used without additional software via any Turck IO-Link master. Device functions are also set via TAS or other IODD interpreters. In addition to process values, additional information such as operating hours and switching cycles can also be output via the digital interface.
