LMK 331

ceramic sensor (flush)
plant and mechanical engineering

The screw-in transmitter LMK 331 has been especially designed for level and process measurement and is suitable for pressure measurement of liquids, oils and gases. Usage in more viscous or polluted media is possible because of the semi-flush pressure sensor.

For the usage in aggressive media we recommended the version with PVDF pressure port. Additional features like e.g. an intrinsically safe version or a functionally safe version (SIL 2) complete the range of possibilities.


  • nominal pressure: 0 ... 400 mbar up to 0 ... 60 bar
  • accuracy: 0.5 % FSO
  • pressure port G 3/4" flush

Optional Features

  • IS-version (only for 4... 20 mA / 2-wire):
    Ex ia = intrinsically safe for gases and dusts
  • SIL 2 application according to IEC 61508 / IEC 61511
  • pressure port PVDF for aggressive media
  • different electrical and mechanical connections
  • customer specific versions
