EJX440A Traditional-mount High Gauge Pressure Transmitter

The EJX-A series is Yokogawa's premium performance line of DPharp transmitters. Released in 2004, 

it offers the performance and stability needed in demanding applications. 

The EJX-A series performance makes it the the thoroughbred of the DPharp family of pressure transmitters.

The EJX440A is the Traditional Mount High Gauge Pressure Transmitter in the series.

The EJX440A Standard features include:

§  ± 0.04% Accuracy

§  ± 0.1% per 15 years Stability

§  90 ms Response Time

§  Exida and TUV SIL 2/3 Certified

§  Local Parameter Setting (LPS)

EJX440A Gauge Pressure Transmitter

The high performance gauge pressure transmitter EJX440A features single crystal silicon resonant sensor and is suitable to measure liquid, 

gas, or steam pressure. The EJX440A 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. The multi-sensing technology provides the advanced 

diagnostic function to detect such abnormalities as an impulse line blockage or heat trace breakage. FOUNDATION Fieldbus and 

PROFIBUS PA protocol types are also available. All EJX series models in their standard configuration, with the exception of the 

Fieldbus and PROFIBUS types, are certified by TÜV as complying with SIL 2 for safety requirement.
