As already mentioned, sensor technology plays a central role in our systems. For the functionality of our sensors, we work with thermocouples. These make use of the thermoelectric effect, a principle from thermophysics: even small temperature differences at the thermocouples can be converted into electrical energy. Since our sensors are designed to be energy-saving, they operate absolutely energy-autarkic during their runtime and therefore do not require an external power source. But this is not the only advantage of our patented sensor system “TOC”.
In addition to absolute energy self-sufficiency, the Thermal Observation Contactless System offers wireless operation and an exceptionally robust design. Thus, the sensor unit itself is not only very accurate, but also well protected against external influences or extreme operating conditions. The IP56 protection class makes the TOC system immune to dust, dirt and moisture. In addition to a tolerance for ambient temperatures of -20 to 55° Celsius, the system provides measured values from -20 to 100° Celsius.
At ten-second intervals, the sensor measures temperature and produces a detailed reading every 120 seconds, which is then transmitted to the associated control unit of your control cabinet temperature control system. The frequency of the readings allows for a quick response to unforeseen changes, providing important stability to the temperature control system. If the measured temperature changes by more than 2 Kelvin in less than 120 seconds, a value is transmitted immediately so that this change can be reacted to as quickly as possible.
The transmission by the TOC system takes place on 868 MHz radio frequency. If you want a higher security for the transmission of your data, other frequencies for transmission are also possible.
