Hygenic Diaphragm Pressure Transducer

The ESI PR3800 series is a range of pressure transmitters with integrated or remote barrier seals for applications where direct media contact must be prevented. Robustly constructed from stainless steel, this range of pressure transmitters incorporates the latest strain gauge technology, together with a custom IC amplifier, which offers excellent stability and accuracy over a long service life. The range offers a stable and accurate output signal of 4-20 mA with options for 0-5 V and 0-10 V. Typical applications include food processing, pharmaceutical, petrochemical, waste water and slurry handling. In these installations the process media may corrode the sensing diaphragm or clog the narrow pressure inlet on a standard transmitter. The flush membrane can be easily cleaned for long term reliability and outstanding performance. For hygienic applications the PR3800 series provides a sanitary grade pressure fitting. Seals are available in a variety of forms and materials for a wide range of applications and can be directly attached to the proposed connection or remotely via stainless steel capillary. Pressure ranges available from 0-200 mbar to 0-40 bar. An optional IECEx approved versions of this range are available for explosion protection for flammable gases (zone 0), dusts (zone 20) and mining areas (group I M1).
