Description

Thanks to its capacitive ceramic sensor element, the LMK 351 screw-in pressure sensor is designed for measuring pressure and level in smaller systems and containers.

It has a pressure range pressure of 0 – 40 mbar up to 0 – 20 bar, at an accuracy of 0.35% full-scale output.  A higher 0.25% accuracy screw-in pressure sensor is available on request.

Its flush-mounted design means it is suitable to use in viscous and pasty media.  In addition, for more aggressive media the LMK 351 screw-in pressure sensor can come with a PVDF or PP-HT pressure port. The AI2O3 99.9 % diaphragm is now standard for the LMK 351.

Plus, for particularly hazardous environments, we can provide an intrinsically safe version for use in fuels and oils. Contact our technical team for more information.
