screw-in transmitter LMK 351

LMK 351

ceramic sensor (flush)
environmental industry, renewable energy

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 complete the range of possibilities.


  • nominal pressure: 0 ... 40 mbar up to 0 ... 20 bar
  • accuracy: 0.25 % / 0.35 % FSO
  • pressure port G 1 1/2" for pasty and polluted media

Optional Features

  • accuracy according to IEC 60770: 0.25 % FSO
  • IS-version
  • Ex ia = intrinsically for gases and dusts
  • pressure port PVDF for aggressive media
  • diaphragm pure ceramic (99,9 % Al2O3)
  • customer specific versions
