The stainless steel probe LMK 387 was developed for level and gauge measurement in wastewater, sludge or water courses. The mechanical robustness of the front-flush ceramic diaphragm faciliates an easy disassembly and cleaning of the probe in case of service. Compared to the level probe LMK 382 the outside-diameter is only 22 mm, which allows an easy installation and backfitting in 1" tubes or in cramped fitting conditions. An IS-version is also available. Features: - nominal pressure: from 0 ... 4 mH2O up to 0 ... 100 mH2O - accuracy: 0.35 % FSO - diameter 22 mm - excellent long term stability - highly appropriated for wastewater, sludge and viscous media Optional Features: - diaphragm ceramics 99.9% Al2O3 (on request) - IS-version (in preparation), Ex ia = intrinsically safe for gases and dust - mounting with stainless stell tube - different kinds of cable - different kinds of elastomer
