EJX438A outputs a 4 to 20 mA DC signal

corresponding to the measured pressure. It also

features quick response, remote setup and monitoring

via BRAIN or HART communications, and diagnostics

and optional status output for pressure high/low alarm.

The multi-sensing technology provides the advanced

diagnostic function to detect such abnormality as an

impulse line blockage. FOUNDATION Fieldbus protocol

type is also available. All EJX series models in their

standard configuration, with the exception of the

Fieldbus type, are certified by TüV as complying with

SIL 2 for safety requirement.
