Sensor technology: Sensitive, but no mimosas
Sensors usually play a central role in Dr. Neumann Peltier technology systems. Like so many parts in the field of electrical engineering, they are also modeled on a human organ: the sensory organs.
Robotic arms mimic human extremities, CPUs the computing power of a brain, and motors the power of our muscles. In this scheme, sensors take over all the impressions that we humans can perceive through our senses. Pressure, temperature, olfactory influences or visual stimuli. In our products, we naturally focus mainly on one area: temperature.
Sensor technology – man against machine
In the same way that our body uses external stimuli to tell us that we are too cold or too warm, sensors transmit thermal data to the control unit, which then corrects the temperature. However, instead of opening the window or turning up the heating, as we do, the temperature is adjusted in the tenths of a Kelvin range. This is an important function for the overall performance of our control cabinet cooling systems, because without a sensitive sensor system, precise and reliable temperature control would be difficult to achieve.
Manual measurement, manual temperature adjustment and regular monitoring of the system make control cabinet temperature control without an automated system not only time-consuming, but also prone to errors. Unfortunately, when such sensitive tasks are in the hands of humans, it cannot be ruled out that either work is not done thoroughly enough or other errors occur. The consequences of a poorly tempered control cabinet are probably known to everyone who has ever experienced a minor system error. In the worst case, overheating of the units can lead to a total failure, or if they cool down too much, condensation can form with subsequent water damage to the electronic units inside the control cabinet.
In order to avoid these scenarios, we at Dr. Neumann Peltier-Technik have made it our business to offer you an all-round happy system for control cabinet temperature control. Fast installation, easy operation, highest quality and reliable performance with only one goal: Uncompromising efficiency.
Self-sufficient, robust and accurate
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.
Flexible bean counter: sensor technology
Our sensors are equipped with a practical mounting frame, which on the one hand creates a perfect thermal separation from the control cabinet exterior and on the other hand gives the TOC system another decisive advantage. Highest flexibility in shoring. Whether drilling holes for screws or other manipulations – there is no place where our TOC system cannot be installed.
The contact point to the measuring object is covered with a special graphite heat conducting foil. Thus, a high accuracy of the measurement result is guaranteed and at the same time the potential equalization to the environment is created.
