Yokogawa EJA118E Differential Pressure Transmitter with Remote Diaphragm Seals


General Specifications

Diaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly

of the differential pressure transmitter, they are connected to the transmitter using capillaries filled with fill fluid.

EJA118E Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas,or steam flow,

as well as liquid level, density, and pressure. EJA118E outputs a 4 to 20 mA DC signal corresponding to the

measured differential pressure.

Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral

indicator or remotely monitored via BRAIN or HART communications. Other key features include quick response,

remote set-up using communications,and self-diagnostics.

FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 VDC with HART (Low Power) protocol types are also available.

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.

PERFORMANCE SPECIFICATIONS

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.

For Fieldbus and PROFIBUS communication types, use caribrated range instead of span in the following specifications.

Specification Conformance

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

Static Pressure Signal Range and Accuracy

(For monitoring via communication or on indicator. Includes terminal-based linearity,hysteresis, and repeatability)

Range

Upper Range Value and Lower Range Value of the statice pressure can be set in the range between 0 and Maximum Working Pressure (MWP*). The upper range value must be greater than the lower range value. Minimum setting span is 0.5 MPa (73 psi).

* : Maximum Working Pressure (MWP) is within flange rating pressure.
