EMP 2 Pressure Transmitter

Brand: Danfoss

The high accuracy pressure transmitter EMP 2 is designed for monitoring and control in marine and industial applications and offers a reliable pressure measurement, even under harsh environmental conditions. 

The flexible pressure transmitter programme covers absolute or gauge (relative) versions with zero and span adjustment with a 4-20 mA output signal. It has all the necessary marine approvals. 

Special versions with integrated pulse-snubber available, designed for use in hydraulic applications with severe medium influences like cavitation, liquid hammer or pressure peaks.
