Yokogawa EJA440E High Gauge Pressure Transmitter Traditional Mount Type

Product Specification

EJA440E Traditional-mount High Gauge Pressure Transmitter

EJA440E Gauge Pressure Transmitter

General Specifications

The high performance gauge pressure transmitter EJA440E features single crystal silicon resonant sensor

and is suitable to measure liquid, gas, or steam pressure. The EJA440E 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 self-diagnostics.

FOUNDATION Fieldbus, PROFIBUS

PA and 1 to 5 V DC 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.

SPAN AND RANGE LIMITS

PERFORMANCE SPECIFICATIONS

Zero-based calibrated span, linear output, wetted parts material code ‘S’ and silicone oil, unless otherwise mentioned.

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

Specification Conformance

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

Reference Accuracy of Calibrated Span

(includes the effects of terminal-based linearity,hysteresis, and repeatability)

Yokogawa's pressure transmitters have a long-term stability under all operational conditions.

As you gain experience with these transmitters, you will be able to extend the time between calibration checks.

Quicker Maintenance = Less Downtime

Yokogawa offers several platforms to communicate to your transmitter.
FieldMate is a PC based communication platform that can communicate with your transmitter and manage your entire instrument inventory.
FieldMate HHC is a traditional hand-held platform that allows you to take that information into the field.
Forgot your HHC? No problem. The LPS feature on the transmitter allows you to update 9 parameters without the use of an HHC.

Quicker Maintenance = Less Downtime

When your transmitter is 'alarming', you do not have the time to look for the manuals and go through them trying to figure out what is wrong; you need to get the transmitter up and operating again as quick as possible. Yokogawa's pressure transmitters have a simple description of the error code available on the local display. This simple description may help you correct the problem and get back to making product quickly. If you need more help, the manual does have a full description of all codes and suggest corrective actions.

Quicker Maintenance = Less Downtime

Pressure transmitters on the market have several different flange configuration depending on the medium being measured (Gas or liquid). This requires plants that process both medium to maintain a stock of both types of configurations. Yokogawa's pressure transmitters offer a universal mount that can be configured to handle either Gas or Liquid; reducing your inventory of replacement transmitters.

High Inventory = Stagnant Money

Yokogawa's pressure transmitters use the industry standard IEC61518 process connection demensions. This ensures you will not need proprietary manifolds or accessories that limit your design choices. The IEC61518 standard gives you the piece of mind that if you ever want to make a change in transmitter manufacturer, you can. Some competitors have proprietary process connections that do nothing more than lock you into buying their product as replacements.
