The screw-in probe LMK 351 is particularly suitable for detecting system pressures and levels in vessels. The LMK 351 is based on a capacitive ceramic sensor element developed in-house, which is mounted flush and thus also enables use in viscous and pasty media.
For use in aggressive media, the pressure connection is optionally available in PVDF and the separating diaphragm in AI2O3 99.9 %. An intrinsically safe Ex version rounds off the profile.ht.
