LMK 487 Nominal pressure from 0 ... 1 mH2O up to 0 ... 100 mH2O Output signals 2-wire: 4 ... 20 mA others on request Probe for Marine and Offshore 22 mm Ceramic Sensor accuracy according to IEC 60770: 0.25 % FSO 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. Special characteristics ► diameter 22 mm ► LR-certificate (Lloyd's Register) ► DNV-GL Approval (Det Norske Veritas ■ Germanischer Lloyd) ► diaphragm 99.9 % AhO3 ► high long-term stability Optional versions ► housing material titanium ► IS-version Ex ia = intrinsically safe for gas and dust ► temperature element Pt 100 ► different kinds of elastomer Beside the housing materials stainless steel and titanium, different elastomer materials are available by which an optimum adaptation to the application can be ensured. Preferred areas of use Water drinking water abstraction desalinization plant Shipbuilding / Offshore ballast tanks monitoring of a ship's position and draught level measurement in ballast and storage tanks www.bdsensors.de info@bdsensors.de BD SENSORS GmbH BD-Sensors-StraBe 1 D - 95199 Thierstein
