1 DRUCK & TEMPERATUR LEITENBERGER GMBH LMK 87 Stainless Steel Probe Ceramic Sensor accuracy according to IEC 60770: standard: 0.5 % FSO option: 0.5 % FSO Nominal pressure from 0... mh O up to mh O Output signals -wire: ma -wire: V others on request Special characteristics diameter mm diaphragm ceramics 96% Al O good long-term stability especially for waste water, Optional versions diaphragm ceramics 99,9% Al O IS-version Ex ia = intrinsically safe for gases and dust mounting with stainless steel tube different kinds of cable different kinds of elastomer The stainless steel probe LMK 87 was developed for level and gauge measurement in wastewater, sludge or water courses. The mechanical robustness of the front-flush ceramic diaphragm facilitates an easy disassembly and cleaning of the probe in case of service. Compared to the level probe LMK 8 the outside-diameter is only mm, which allows an easy installation and backfitting in tubes or in cramped fitting conditions. An IS-version is also available. Preferred areas of use Water Groundwater and level monitoring Sewage waste water treatment water recycling Fuel and oil Tank battery Biogas plants
