EJA120E Draft Range Differential Pressure Transmitter

The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family of pressure transmitters. 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 EJA120E is the traditional-mount Draft Range Pressure Transmitter in this series.

EJA120E features include:

  • ± 0.2% Accuracy (0.09% available with /HAC option)
  • ± 0.3% per 1 year Stability
  • 150 ms Response Time
  • Exida and TUV SIL 2/3 Certified
  • Local Parameter Setting (LPS)
  • True Draft Range design

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

EJA120E Draft Range Differential Pressure Transmitter-Overview

At it's heart, Yokogawa's Differential Pressure Transmitter with DPharp digital sensor offers the performance and device intelligence needed to get greater insight into your process.

Plants run better with Yokogawa pressure transmitters.

Digital Performance

Digital Performance

Poor Performance = Lost Money

Installed performance 2x better using all digital DPharp pressure sensor.

Yokogawa’s digital sensor provides superior performance and stability compared to analog sensors.

Dynamic Compensation

Compensates for process changes to improve accuracy.

 



 

 

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

Ruggedly constructed differential pressure transmitter can help your plant reduce failures. Yokogawa's DP transmitters have construction features that are designed to allow it to outlive your plant. Four-bolt ressure retaining design, Active DPharp sensor, and dual seal certified to ANSI/ISA 12.27.01 - all design features to extend the life of the transmitter.

Ruggedness = Reliability

 


 

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 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

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.

 


 

Standard Industry Connections

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