greenTEG’s heat flux and radiation sensing technology wins the 2013 Product Award
Zürich, Switzerland - greenTEG’s heat flux and radiation sensing technology has won the 2013 Product Award bestowed by the Swiss Excellence Foundation. With this award, the Swiss Excellence Foundation attests to greenTEG’s technology a high degree of innovation, and great potential for added value.
gSKIN sensors measure heat flows and radiation quickly and with high precision. The sensor is applied in thermal characterization of materials and buildings, as well as for the measurement of laser power and solar radiation. Furthermore, the sensor can be used for controlling systems in smart building technologies (heating, ventilation, shading and many more), and industrial process control. The technology is currently integrated in laser measurement tools of companies like Thorlabs. Alstom Switzerland and similar companies use the sensor in various industrial applications.
Increased Energy Efficiency of Buildings
In the field of building science, gSKIN sensors help to increase energy efficiency: by determining where in a building the most heat is lost. It also enables the assessment of the thermal quality of built in insulations. A further application within building science is the management of heating, ventilation and shading systems via gSKIN sensors. Compared to common thermal sensors, the gSKIN has clear advantages. It does not measure temperature, but rather heat flows and can therefore provide important information in dynamic systems, enabling more efficient control.
Measuring Laser Power
Laser power measurement is an important application of the gSKIN®. In the manufacturing industry and in medical applications, lasers are omnipresent. The sensor helps to control the laser and therefore ensures that the right amount of laser power is always hitting the target. The small dimensions of the gSKIN® is a further decisive advantage. It makes the integration into existing systems easy. “To further reduce the wastage rate and for a more cost efficient maintenance of their systems, continuous process monitoring becomes increasingly important for our customers” says Peter Stein, Head of Sales and founding member of greenTEG AG.
The sensor is based on thermopile technology. Two different semiconductors with different thermoelectric properties are integrated as small piles into a substrate. The piles are connected in series and protected from external influences with a thin aluminum cover. As thermal energy flows through the sensor module, a thermal voltage builds up which is then read out with a datalogger or a voltmeter.
