Hydrostatic Level Sensor LMP 331i

The screw-in transmitter LMK 351 has been designed for measuring small system pressure and level measurement in container. The LMK 351 is based on an own-developed capacitive ceramic sensor element. Usage in viscous and pasty media is possible because of the flush mounted sensor. For the usage in aggressive media a pressure port in PVDF and the diaphragm in AI2O3 99.9 % is available. An intrinsically safe version complete the range of possibilities. 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

The screw-in transmitter LMP 331 has been designed for continuous level measurement and is characterized by an excellent performance and a robust construction. The modular construction allows the user the highest possible flexibility in the adaption of LMP 331. Optional features like e.g. an intrinsically safe version or a functionally safe version (SIL 2) increase the advantages when launching and realizing projects for plants and systems. Features — nominal pressure: 0 ... 100 mbar up to 0 ... 40 bar — accuracy: 0.35 % (opt. 0.25% / 0.1 %) FSO — small thermal effect — excellent long term stability — pressure port G 3/4" flush Optional Features — IS-version Ex ia = intrinsically safe for gases and dusts — SIL 2 application according to IEC 61508 / IEC 61511 — different electrical connections — customer specific versions e.g. special pressure ranges

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. 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

The LMP 308i is designed for continuous fill level and level measurement of water and liquid mediums. The signal processing of sensor signal is done by digital electronics with 16-bit analog digital converter. Consequently it is possible to conduct an active compensation of sensor intrinsic deviations from normal condions like nonlinearity and thermal error. In order to facilitate stock-keeping and maintenance the transmitter body is plugged to the cable assembly with a connector and can be changed easily. Features: — nominal pressure: 0 ...4 mH2O up to 0...200 mH2O — accuracy: 0.1 % FSO — diameter 35 mm — cable and sensor section separable — thermal error in compensated range -20...70°C: 0.2 FSO TC 0.02% FSO/10K 0,02 % FSO / 10K — high accuracy — communication connection — turn-down 1:10 Optional Features: — IS-version — mounting accessories as cable gland and terminal clamp in stainless steel
