  • Robust design for permanently precise measurements even in demanding environments

Improved performance thanks to IO-Link

  • Transparent sensor monitoring thanks to logging of the diagnostic values
  • Simulation function simplifies installation

Maximum reliability for temperature-sensitive processes
Thanks to the improved inline calibration process, the TCC achieves an accuracy of ± 0.2 K across the entire measuring range. This makes it perfectly suited for use in temperature-sensitive processes such as food, rubber or carbon processing. Besides, the TCC ensures a smooth process and a high product quality by permanently monitoring its own reliability. If the sensor deviates from the individually defined tolerance values or in the event of a sensor malfunction, it provides a corresponding signal via the clearly visible LED and the diagnostic output.

Robust design for long-time use
Thanks to its fully welded and sealed housing and a new measuring probe design, the TCC is permanently resistant to external influences such as moisture, thermal and mechanical shocks and vibrations.

Permanent status checking
Thanks to the calibration check technology, the TCC permanently checks its own drift behaviour. The sensor compares the temperature value to the simultaneously measured reference value. If the deviation is outside the tolerance range, which can be set between 0.5 and 3 K, the TCC provides an optical signal and sends a message to the central controller via IO-Link and the diagnostic output. The same applies to cases of serious malfunctions.

Quality assurance thanks to event-related measures
Particularly in production processes where exact temperature values are decisive for the product quality, it is important that the measured values are absolutely precise. The TCC allows plant operators to take event-related measures in case of drifts – instead of waiting for the next planned calibration interval. This reduces the risk of losing entire production batches due to faulty production temperatures.

Transparent sensor communication
Visual and digital indication: The TCC provides the current status in a simple and clear way. If the LED on the sensor is green, the unit operates reliably. Blue indicates a temperature deviation outside the tolerance range. Red indicates a serious malfunction, such as a failure of the main measuring element. Besides, the TCC automatically stores all the data required for consistent documentation via IO-Link: installation date, operating hours, temperature histogram as well as logbooks on event messages (operating hours and event number) and on the calibration check status (operating hours, temperature value, drift value, limit and status).

Simulation mode: guaranteed reliability even before installation
The value from which the TCC provides a message can be defined via software. In the simulation mode, the process temperature and the reference temperature, among others, can be freely selected to verify whether the sensor has been correctly integrated into the controller. This process simulation completes the high level of reliability offered by the TCC.
