LMK 387H Stainless Steel Probe with HART®-communication Ceramic Sensor accuracy according to IEC 60770: standard: 0.35 % FSO option: 0.25 % FSO Nominal pressure The stainless steel probe LMK 387H was developed for level and gauge measurement in wastewater, sludge or water courses. The mechanical robustness of the flush ceramic diaphragm facilitates an easy disassembly and cleaning of the probe in case of service. from 0 ... 1 mH2O up to 0 ... 100 mH2O Output signals 2-wire: 4 ... 20 mA others on request The outer diameter is only 22 mm, whereby the installation or retrofitting can be easily carried out in 1 "pipes or in confined installation conditions. In addition to an intrinsically safe version (zone 0), a version with temperature signal is available. HART® communication (revision 7) setting of offset, span and damping good long-term stability especially for waste water Preferred areas of use Water groundwater and level monitoring housing material titanium IS-version Ex ia = intrinsically safe for gas and dust drinking water certificate according to DVGW and KTW Fuel and oil tank battery biogas plants Sewage waste water treatment water recycling different kinds of elastomer BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
