LMK 487 Probe for Marine and Offshore 22 mm Ceramic Sensor accuracy according to IEC 60770: 0.25 % FSO Nominal pressure The hydrostatic probe LMK 487 has been developed for measuring levels in various tank applications for shipbuilding and offshore. In comparison to the hydrostatic probe LMK 458 the external diameter amounts to only 22 mm by which the installation in 1" pipes can be carried out easily. from 0 ... 1 mH2O up to 0 ... 100 mH2O Output signals 2-wire: 4 ... 20 mA others on request Beside the housing materials stainless steel and titanium, different elastomer materials are available by which an optimum adaptation to the application can be ensured. LR-certificate (Lloyd´s Register) DNV▪GL Approval (Det Norske Veritas ▪ Germanischer Lloyd) high long-term stability Preferred areas of use Water drinking water abstraction desalinization plant housing material titanium IS-version Ex ia = intrinsically safe for gas and dust Shipbuilding / Offshore ballast tanks monitoring of a ship’s position and draught level measurement in ballast and storage tanks different kinds of elastomer BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
