LMK 458H Probe with HART®-communication for Marine and Offshore Ceramic Sensor Nominal pressure The hydrostatic probe LMK 458H has been developed for measuring level in service and storage tanks and is certificated for shipbuilding and offshore applications. from 0 ... 60 cmH2O up to 0 ... 200 mH2O Output signals 2-wire: 4 ... 20 mA others on request A permissible operating temperature up to 85°C and the possibility to use the device in intrinsic safe areas enable to measure the pressure of various fluids under extreme conditions. The basis for the LMK 458H is a self-developed capacitive ceramic sensor element, which offers a high overload resistance and medium compatibility. shipping approvals acc. to: Lloyd´s Register (LR), Det Norske Veritas (DNV), China Classification Society (CCS), American Bureau of Shipping (ABS) HART® communication (setting of offset, span and damping) Water drinking water abstraction desalinization plant high overpressure resistance high long-term stability IS-version Ex ia = intrinsically safe for gas and dust different housing materials (stainless steel, CuNiFe) screw-in and flange version Shipbuilding / Offshore ballast tanks draught monitoring level measurement in ballast and storage tanks accessories e. g. assembling and probe flange, mounting clamp BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
