LMP 331i

The LMP 331i screw in transmitter displays the furthest in developments of
industrial pressure transmitters.

The signal processing of sensor signal is done by electronics with a 16-bit analog digital convertor. Therefore, it is a possibility to conduct an active compensation and the transmitters with exceptional measures and notably attractive prices to offer on the market.

Product Features:

  • Nominal pressure: 0 … 400 mbar up to 0 … 40 bar
  • Accuracy: 0.1 % FSO
  • Thermal error in compensated range -20 … 80 °C: 0.2 % FSO TC 0.02 % FSO /
    10 K
  • Turn-down 1:10
  • Communication interface for adjusting of offset, span, and damping

Optional Features:

  • IS-version
  • Ex ia = intrinsically safe for gases and dusts
  • Adjustment of nominal pressure gauges (factory-provided)

LMK 331

The LMK 331, screw in transmitter was specifically made for level and process measurement. Consequently, it is suitable for pressure measurement of liquids, oils, and gases. Use in viscous or polluted media is now made possible thanks to
the semi-flush pressure sensor.

For use in aggressive media, it is recommended to use the version with PVDF pressure port. The range of possibilities is completed due to additional features such as an intrinsically safe version or a functionally safe version (SIL 2).

Product Features:

  • 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

LMK 351

The LMK 351, screw in transmitter, has been especially designed to measure small system pressure and level management in container. An own-developed capacitive ceramic sensor element is what the LMK 351 is based on. Thanks to the flush mounted sensor, use in viscous and pasty media is made possible.

In the case of aggressive media, a pressure port in PVDF and the diaphragm in AI203 99.9% is available. The range of possibilities has been completed by an intrinsically safe version.

Product Features:

  • Nominal pressure: 0 … 40 mbar up to 0 … 20 bar
  • Accuracy: 0.35 % (opt. 0.25 %) FSO
  • Pressure port G 1 1/2" for pasty and polluted media

Optional Features:

  • IS-version
  • Ex ia = intrinsically for gases and dusts
  • Pressure port PVDF for aggressive media
  • Diaphragm pure ceramic (99,9 % Al2O3)
  • Customer specific versions

LMP 305

The LMP 305 Slimline probe, made with silicone stainless steel sensor has been designed for continuous level measurements in confined space cases. Permissible media can be clean or wastewater thin fluids.

This piezoresistive stainless steel sensor with low thermal error features exceptional linearity and long-term stability, is basis LMP 305.

Product Features:

  • Nominal pressure: 0 … 1 mH2O up to 0 … 250 mH2O
  • Accuracy: 0.35 % (opt. 0.25 %) FSO
  • Diameter 19 mm for cramped areas e.g., 1" observation well
  • Small thermal effect
  • Excellent linearity
  • Excellent long-term stability

Optional Features:

  • Different kinds of cable
  • Customer specific versions e.g. special pressure ranges
