Description
The Hengesbach PZM 100/101 pressure transmitters are suitable for taking pressure and filling level measurements in pipelines and containers. The modular process connection system offers a wide range of connection adapters and helps to cut costs in the long term.
The flush-mounted process connection with O-ring seal and stainless steel membrane is certified to EHEDG type EL-ASEPTIC CLASS 1 and is thus predestined for measurements which satisfy even the most stringent hygiene requirements.
The sensor measuring ranges of the piezoresistive vacuum-proof measuring cell with stainless steel membrane of the Hengesbach PZM pressure transmitters range from -1/0…0.35bar to -1/0…100bar.
Special measuring ranges are possible for both versions. All the pressure transmitters in series 100/101 are designed for universal applications and, in particular, for applications with constantly high temperatures of up to 200°C. Furthermore, using the on-site display with series 100 and the display and operating module OPUS M in series 101, the pressure transmitters can be simply read out, configured and diagnosed.
