EJA430E Traditional-mount Gauge Pressure Transmitter

The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family. Released in 2012, it combines the ruggedness and success of the work-horse EJA-A series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.

The EJA430E is our traditional-mount gauge pressure transmitter in the series.

EJA430E features include:

  • ± 0.055% Accuracy (0.04% Accuracy optional)
  • ± 0.1% Stability per 10 years
  • 90 ms Response Time
  • Exida and TUV SIL 2/3 Certified
  • Local Parameter Setting (LPS)

Available with HART 5/7, 1 to 5V HART 7 (Low Power), FOUNDATION Fieldbus, PROFIBUS PA, or BRAIN communication.

More Information

Local Indicator

Easy to read indicator provides all the information you need.

 

 

 

 

 

 

Self Diagnostics

Standard Diagnostics

Good Diagnostics = Less Surprises

Reduce unscheduled maintenance by 60%

Over 40 diagnostics to ensure everything is OK. Active Sensor Technology monitors the DPharp sensor while the Patented Back-check Technology is reverse checking all calculations in real-time.

Rugged Construction

 

Independent Verification

The Yokogawa pressure transmitter series' performance and reliability has been verified by independent third parties from around the world.

 

Inherently Safe

All Yokogawa pressure transmitters are designed and certified to IEC61508:2010 Parts 1 through 7 and IEC61511:2004 Parts 1 through 3. They are certified for single transmitter use in SIL 2 safety applications and dual transmitter use in SIL 3 safety applications with no special option required. With Yokogawa EJA-E transmitters, no longer will you have to maintain two seperate inventories - one for production pplications and one for safety applications.

Inherently Safe = Reliability.

 

Active Sensor Technology

Unlike other sensor technologies, the active DPharp sensor constantly produces a signal even if there is no change in the process. This signal is continually monitored by the CPU.

 

Patented Self-check System

All calculations are checked by reverse calculation in real-time ensuring the highest reliability.

Routine maintenance is easier with Yokogawa differential pressure transmitters.

Extended Calibration Intervals

Yokogawa EJA-E series pressure transmitters have a long-term stability 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

Interval Between Calibration Checks

 

Multiple Communication Options

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

 

Simple Troubleshooting

Save time, Save money

Local intuitive display with simple error messaging.

NE107 compliant alarms in FieldMate make troubleshooting easy.

 

Less Inventory

Universal Mounting

Reduce stock by 50%.

Consolidate inventory of different flange configurations. Yokogawa transmitters are available with flanges using flexible vent and drain locations to met any installation need.

High Inventory = Stagnant Money

Standard Industry Connections

Process connections designed to meet IEC61518 ensure you will not meet proprietary manifolds or accessories that limit your design choices.
