Masses of gas or air measures directly.

The perfect flow measurement for pure areas and similarly fastidious ProzesseDie high requirements of modern control engineering in spatial air-technical plants require accurate measuring of the flow rates in air or gases. In addition flow sensors must be able to seize an extremely broad measuring range from almost zero to the maximum value precisely and fast. The new flow sensors SS 20,250 of SCHMIDT Technology are exactly conceived for it. In ranges, in which requirements exist to security for humans or product or to hygenic air conditions, an accurate measurement of the flow rates is of air or gases and not least their documentation necessary. These requirements, can not be fulfilled in spatial air-technical plants with simple push button switches. Perfect a method of flow rates to measure, offer thermal flow sensors. With them air or gas flows can be seized directly. The special advantage of this technology is the far measuring range, which covers in the air condition technology for pure areas or for production processes with comparable requirements, relevant air and/or gas flows completely. That includes smallest air speeds, as for example in rest periods up to maximum currents, under full load. To the thermal Anemometrie so called is salient the simple and precise measurement as well as in the long run the simple evaluation of the seized datapurposefully flow measurement thermal for fastidious cases of application conceive-conceiving those represents also the basis of the again developed flow sensors SS 20,250 of SCHMIDT Technology. Their complete electronics is accommodated in a robust feeler pipe made of metal. A diameter of only nine millimeters makes it to the smallest Allroundern of their art. They represent a minimum slight resistance in the air flow and are easy with little space requirement to install. But there is a wall assembly flange made of high-grade steel in the accessories to flange, Schwei�-Muffe or passage screw connections and for pure space applications particularly interesting. 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 exact aligning in the current. In addition the behind-cut-free and completely beginningless Design restrains adhering of dirt particles and makes an easy cleaning possible. For appropriate requirements the sensors with a chemically resistant protection coat are offered. Thus they are protected from aggressive media such as hydrochloric acid, acetone or sulfuric acid u.v.m. as well as reagents in disinfectants. 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%. With a highly precise ion alignment and an ISO calibration certificate an accuracy of �3% is ensured. In addition ones to the flow rate also the medium temperature is fast-reacting measured. Like capability characteristics and the Design SCHMIDT Technology cut also the price of the SS 20,250 to the range of application. With a list price of 340 � the sensors represent an adequate solution for applications, e.g. to the continuous monitoring of filter units, the controlling of the volume stream when exhausts or the monitoring of laminar flows in pure areas.
