Direct measurement of air volumes with flow sensors
Improving energy efficiency significantly in ventilation and air-conditioning systems
The new flow sensor SS 20.250 from SCHMIDT Technology is a device developed on the basis of thermal flow measurement selectively for applications such as ventilation and air-conditioning systems. A rugged metal sensor tube of only nine millimeters in diameter houses the complete electronics. Thus, the smallest all-rounders of their type offer particular advantages. Since they require little space, they are easy to mount and present minimum resistance in the air flow. For installation in different pipe diameters, sensor lengths of 300 and 500 millimeters are available. The patented dumbbell head can be positioned safely and quickly in the gas flow and does not require accurate alignment in the flow channel. In addition to that, the completely seamless design of the sensor head free of undercuts inhibits the adhesion of dirt particles, thus making it easy to clean an usable in dust-containing gases.
The standardized flow rate is detected over a measuring range of 0.06 to 20 m/s. In addition to the flow rate, the temperature of the medium is also measured in quick response. A skillfully integrated two-colored LED display (red, green) at the back end of the sensor tube shows the operating status in clearly visible form.
