LMK331 Bdsensors 1024 Square

LMK 331

The LMK 331 is a screw-in transmitter from BD Sensors, which has been designed to measure level and process. It is applicable to measure also pressure of liquids, oils, and gases. Furthermore, the semi-flush pressure sensor makes it possible to also use the LMK 331 in more viscous or polluted media.

Additionally, this screw-in transmitter is available in an intrinsically safe version or a functionally safe version (SIL 2), which complete the range of possibilities you have with the LMK 331.

Standard LMK 331 Features

The screw-in transmitter LMK 331 is precise and has the following features that benefits you:

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

Furthermore, the screw-in transmitter can be used in various media including:

  • Sewage water, sludge
  • Aggressive media
  • Fuels and oils
  • Water.

If you want to use the transmitter in more aggressive media, the version of the LMK 331 with PVDF pressure port is recommended.
