The screw-in transmitter LMK 351 has been designed for measuring small system pressure and level measurement in container. The LMK 351 is based on an own-developed capacitive ceramic sensor element. Usage in viscous and pasty media is possible because of the flush mounted sensor. For the usage in aggressive media a pressure port in PVDF and the diaphragm in AI2O3 99.9 % is available. An intrinsically safe version completes the range of possibilities.
