With flow sensors amounts of air measure directly

Energy efficiency in ventilation and air conditioning systems significantly improve. Over regular Ventilatorleistungen amounts of air in ventilation and air conditioning systems can be adapted to the actual need and be reduced so the energy consumption significantly. Basis for it is an accurate volume flow measurement. The new flow sensors SS 20,250 of SCHMIDT Technology are exactly conceived for it. Ventilation and air conditioning systems belong in residential buildings, above all however in office and factories as well as in public buildings to the largest energy consumers. The principal items of such plants are fans, whose taken up electricity stands in direct connection with the amounts of air which can be transported. With frequency-steered fans and appropriate control engineering these can be reduced to the minimum need, which is needed for the maintenance of the air quality and the thermal surrounding field. Necessarily for it however an accurate measurement of the flow rates is in a far measuring range. This reaches from almost zero, like it when starting the fans the case is, up to the maximum, which can be in such plants about 20 m/s. Flow rates are ideally detectable with thermal flow sensors directly. This technology offers a measuring range, which takes the air flows off relevant in the air condition technology completely. That includes smallest air speeds, as for example in rest periods up to maximum currents under full load. The special advantage is in the simple and precise measurement as well as in the long run in simple Auswertung.Die of perfect Str�mungsmessungEin on basis of the thermal flow measurement and purposefully for cases of application as in ventilation and air conditioning systems developed equipment is the new flow sensor SS 20,250 from SCHMIDT Technology. In a robust feeler pipe made of metal, with a diameter of only nine, complete electronics is accommodated millimeters. Thus the smallest Allrounder of their kind offers special advantages: they are easy with little space requirement to install, by means of flange, Schwei�-Muffe or passage screw connection from the accessories and them represent in the air flow a minimum slight resistance. For the installation in different pipe diameters are available feeler lengths with 300 and 500 millimeters. The patented Hantelkopf with large angle of attack of radially 360� and axially �45� can be positioned in the gas flow surely and fast and saves the exact aligning of the sensor in the channel. In addition the behind-cut-free and completely beginningless Design restrains adhering of dirt particles and makes an easy cleaning possible. Like that the new SCHMIDT� flow sensors SS 20,250 are suited also for the employment in staubhaltigen gases. The collection of the standard flow rate effected in a measuring range from 0,06 to 20m/s. thereby is the measuring accuracy of the SS 20,250 with �5% and with a highly precise ion alignment and an ISO calibration certificate about �3%. In addition ones to the flow rate also the medium temperature is fast-reacting measured. One skillfully integrated two-colored LED display (red, green) at the rear feeler end of pipe well visibly indicates the operating condition. With a list price of 340 � the sensors represent an adequate solution for the employment with frequency-steered fans for energy conservation in ventilation and air conditioning systems. Picture: The SCHMIDT� flow sensor SS 20,250 is suited for the employment in ventilation and air conditioning systems.
