  • accuracy: 0.5 % FSO
  • pressure port G 3/4" flush
  • ceramic sensor
  • pressure port PVDF for aggressive media

  • areas of application: mechanical and plant engineering, energy industry, medical technology, environmental industry

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.
