Nominal pressure from 0 ... 100 mbar up to 0 ... 600 bar Output signals 2-wire: 4 ... 20 mA others on request Special characteristics ► LR-certificate (Lloyd's Register) ► DNV-GL Type Approval (Det Norske Veritas ■ Germanischer Lloyd) ► ABS-certificate (American Bureau of Shipping) ► CCS-certificate (China Classification Society) ► flush pressure port G 1/2" from 100 mbar ► excellent thermal behaviour DMP 457 Pressure Transmitter for Shipbuilding and Offshore Stainless Steel Sensor accuracy according to IEC 60770: standard: 0.35 % FSO option: 0.25 % FSO The pressure transmitter DMP 457 has been especially designed for rough conditions occurring especially in shipbuilding and offshore applications. All gaseous and liquid media, which are compatible with stainless steel 1.4404 (316L) respectively can be used. Sensor element is a piezoresistive stainless steel sensor with high accuracy and excellent long-term stability. In order to meet the special requirements for shipbuilding and offshore applications extensive tests had to be passed to get the Lloyd's Register (LR), Det Norske Veritas ■ Germanischer Lloyd (DNV^GL) and China Classification Society (CCS) approvals. Diesel engines, drives Compressors, pumps Boiler Hydraulic and pneumatic control systems Optional versions ► IS-version Ex ia = intrinsically safe for gases and dusts ► welded pressure port BD SENSORS GmbH BD-Sensors-StraUe 1 D - 95199 Thierstein www.bdsensors.com info@bdsensors.de

Current consumption 4 Pressure transmitters are calibrated in a vertical position with the pressure connection down. If this position is changed on installation there can be slight deviations in the zero point for pressure ranges Pn S 1 bar. 5 This directive is only valid for devices with maximum permissible overpressure > 200 bar Electrical connections 6 (dimensions in mm) 6 Generally shielded cable has to be used! Cable versions are delivered with shielded cable. For ISO 4400 the use of shielded cable is compulsory. 7 tested at 4 bar or 40 mH2O for 24 hours 8 shielded cable with...
