Yokogawa EJA438E-JBSCG-919DB-WZ2CZSW00-BA26/KS21/M2W Diaphragm Sealed Gauge Pressure Transmitter

It also features quick response, remote setup and  monitoring via BRAIN or HART communications and  self-diagnostics. FOUNDATION Fieldbus, PROFIBUS  PA and 1 to 5 V DC with HART (Low Power) protocol  types are also available. All EJA-E series models  in their standard configuration, with the exception  of the Fieldbus, PROFIBUS and Low Power types,  are certified as complying with SIL 2 for safety  requirement.


Zero-based calibrated span, linear output, wetted  parts material code SW for 3-inch flange flush type,  fill fluid code B, and capillary length of 5 m.

Specification Conformance 

EJA-E series ensures specification conformance to at  least ±3σ.

Reference Accuracy of Calibrated Span (includes terminal-based linearity, hysteresis, and  repeatability)


Response Time (All capsules)  

200 ms (approximate value at normal temperature)  When software damping is set to zero and including  dead time of 45 ms (nominal)

Ambient Temperature Limits

−40 to 60°C (−40 to 140°F) 

−30 to 60°C (−22 to 140°F) with LCD display (Note: The ambient temperature limits must be within the  fill fluid operating temperature range, see table 1.)
