LMK 458 Probe for Marine and Offshore Ceramic Sensor accuracy according to IEC 60770: standard: 0.25 % FSO option: 0.1 % FSO Nominal pressure The hydrostatic probe LMK 458 has been developed for measuring level in service and storage tanks and is certificated for shipbuilding and offshore applications. from 0 ... 40 cmH2O up to 0 ... 200 mH2O Output signals 2-wire: 4 ... 20 mA others on request A permissible operating temperature up to 125 °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 458 is a capacitive ceramic sensor element designed by BD|SENSORS, which offers a high overload resistance and medium compatibility. LR-certificate (Lloyd´s Register) DNV-approval (Det Norske Veritas) ABS-certificate (American Bureau of Shipping) CCS-certificate (China Classification Society) high overpressure resistance high long-term stability Preferred areas of use are Water drinking water abstraction desalinization plant Optional versions Shipbuilding / Offshore ballast tanks monitoring of a ship´s position and draught level measurement in ballast and storage tanks different housing materials (stainless steel, CuNiFe) IS-version Ex ia = intrinsically safe for gas screw-in and flange version accessories e.g. assembling and probe flange, mounting clamp BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
