The DS200 differential pressure sensor is used to measure small differential pressures in ventilation and air conditioning systems. In combination with an effective pressure transducer (for example, a venturi nozzle, a venturi tube, a measuring diaphragm), suitable for the calculation of the volumetric flow.

Known fields of application are: Ventilation systems, room pressure monitoring, filter monitoring process, environmental, clean room technology, fan technology, pump technology, suction technology, pressure switch.

All our differential pressure transducers of the DS series have our optimized mechanical measuring system MENSIO. The MENSIO has been steadily developed over many years and has always proved itself against all adversities. It is particularly characterized by its precision, longevity and insensitivity to external influences.
