Our DE91 differential pressure transmitter from the FISCHER PRO-LINE® is suitable for ultra-low pressure measurements. This device, like our other FISCHER PRO-LINE® products, is also available as a two-channel version. The built-in sensor, with an overpressure resistance of 100kPa, is known for its reliability, precision and long-term stable performance and is based on many years of experience and is tried and tested. It can also be used in ATEX zones 2 and 22. Typical areas of application include pressure equalisation in clean rooms, measurement of burner vacuum, control of circulating air in ovens, volume flow measurement, precise measurements in air ducts, dynamic monitoring of filters and applications in filter technology.
