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 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 a container. A BD 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: from 0 … 1 mH2O up to 0 … 100 mH2O
- Accuracy: 0.35 % (opt. 0.25 %) FSO
- Diameter 22 mm
- Diaphragm ceramics Al2O3 (99.9 %)
- Excellent long-term stability
- Highly appropriated for wastewater, sludge, and viscous 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
LMK 387
The LMK 387 was developed to measure level and gauge in wastewater, sludge, or other bodies of water. It’s a stainless steel probe. The front-flush system makes it easy to disassemble and clean when needed.
Product Features:
- Nominal pressure: 0 … 1 mH2O up to 0 … 250 mH2O
- accuracy: 0.35 % (opt. 0.25 %) FSO
- diameter 22 mm
- diaphragm ceramics Al2O3 (99.9 %)
- excellent long term stability
- highly appropriate for wastewater, sludge and viscous media
Optional Features:
- Housing material titanium
- IS-version Ex ia = intrinsically safe for gas and dust
- Drinking water certificate according to DVGW and KTW
- Temperature element Pt 100
- Mounting with stainless steel tube
- Different kinds of cables and elastomers
LMP 305
The LMP 305 Slimline probe, made with 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:
