LMK 331 was specially developed for level and process measurement technology and is suitable for pressure detection of liquids, oils and gases. The flush mounting of the pressure sensor allows the use even in viscous or contaminated media.
For aggressive media, the variant with PVDF pressure connection is particularly recommended. Additional features such as an intrinsically safe Ex version or a safety-compliant variant (SIL 2) round off the profile.
