Marine approved stainless steel diaphragm pressure transmitter with 4-20mA current loop output for shipbuilding in ranges from 100mb to 600 bar gauge or absolute.
The DMP 457 marine pressure transmitter has a silicon strain gauge sensing diaphragm protected with a stainless steel oil filled capsule which is compatible with marine applications that do not involve contact with seawater or salt spray such as disel engines, compressors, pumps, boilers, hydraulic and pneumatic controls.
The DMP457 pressure transmitter is Germanischer Lloyd (GL) and Det Norske Veritas (DNV)approved for marine use and can be used below deck on ship systems.
ATEX approved for intrisically safe use in hazardous environments the DMP 457 marine pressure transmitter is also available for ship systems which are handling flammable and volatile chemicals such as oil, gas, liquid petroleum gas (LPG) and liquid natural gas (LNG).
