Product Description
The transmitter converts process pressure into a proportional 4–20 mA signal for transmission to a vessel’s automation, alarm or control system. HART communication permits configuration, calibration and diagnostic access through the same two-wire loop.
Typical marine applications include:
- Main- and auxiliary-engine pressure monitoring
- Fuel- and lubricating-oil systems
- Cooling-water and compressed-air systems
- Boiler and feedwater pressure measurement
- Pump discharge and suction monitoring
- Cargo, ballast and utility systems
- Retrofit of obsolete pressure transmitters
