Product catalog summary

Overview: The LMK 382H is a stainless steel probe designed for continuous level measurement in various fluids, featuring HART® communication and a ceramic sensor. It offers high accuracy and stability, suitable for environments with sewage, polluted, and high-viscosity fluids.

Specifications:

Accuracy: 0.1% FSO according to IEC 60770.
Nominal Pressure: Ranges from 0.06 to 20 bar, equivalent to 0.6 to 200 mH2O.
Output Signal: Standard 2-wire, 4-20 mA with HART® communication.
Temperature Range: Up to 85°C permissible.
Materials: Housing made of stainless steel 1.4404 (316L), diaphragm options include ceramics Al2O3 96% or 99.9%.

Features:

High overpressure resistance and long-term stability.
Optional versions include intrinsically safe (IS) for gas and dust, mounting with stainless steel pipe, and flange version.
Adjustable parameters such as electronic damping, offset, and span.

Applications:

Water: Groundwater level measurement, rain spillway basins.
Sewage: Wastewater treatment, water recycling.
Fuel and Oil: Level monitoring in open tanks, fuel storage, tank farms, biogas plants.

Performance:

Accuracy varies with pressure range and turn-down ratio (TD).
Long-term stability is ≤ ± (0.1 x turn-down) % FSO/year.
Thermal effects are within a tolerance band of ≤ ± 1% FSO in the compensated range of -20 to 80°C.
