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. 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-approval (Det Norske Veritas) ABS-certificate (American Bureau of Shipping) CCS-certificate (China Classification Society) flush pressure port G 1/2" from 100 mbar excellent thermal behaviour Preferred areas of use are Diesel engines, drives Compressors, pumps Boiler Hydraulic and pneumatic control systems IS-version Ex ia = intrinsically safe for gases and dusts 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 (DNV) and China Classification Society (CCS) approvals. welded pressure port BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
