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.

Explore how the EJA120E can help you Boost your bottom line.

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.

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.

Yokogawa's DPharp active sensor, patented back check diagnostics, and rugged construction allow users to run their plants safer and with less downtime.

Yokogawa pressure transmitters help plants run longer.

Rugged Construction

Rugged Construction

Ruggedness = Reliability

Reduce failures in the field by 200%.

Yokogawa transmitters are designed to out live your planet.

 

Over-pressure Protection

Reduce failures and calibrations.

Yokogawa DPharp pressure transmitters have an integral over-pressure mechanism to protect your transmitters from process surges or improperly sequenced manifolds.

Proven Technology

Proven in Use

Less Downtime = Making Product

Over 6 million DPharp transmitters are installed worldwide.

 

Reliability Guaranteed

Reliability verified independently by third party industry experts.

Inherently Safe Design

Inherently Safe

Inherently Safe = Reliability

Save up to 10% on CAPEX spending.

All Yokogawa pressure transmitters are certified to meet IEC61508 for single use in SIL 2 applications or dual use in SIL 3 applications as a standard. No special option needed! To Yokogawa, safety should never be an option.

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.

Efficient and effective maintenance through extended calibration intervals and simple trouble shooting.

Routine maintenance is easier with Yokogawa pressure transmitters.

Long Calibration Intervals

Extended Calibration Intervals

Reduce maintenance cost by 33%.

Improved long-term stability extends calibration intervals. Spend your time where it is needed.

Quicker = Less Downtime

Multiple Communication Options

Save time, Save money

FieldMate PC based communication platform allows management of your entire instrument inventory.

FieldMate HHC allows you to take that information into the field.

LPS can update 9 parameters in the field without the use of an HHC.

Simple Troubleshooting

Save time, Save money

Local intuitive display with simple error messaging.

NE107 compliant alarms in FieldMate make troubleshooting easy.

No Learning Curve

Standard Protocols

No training required.

Yokogawa transmitters support all industry standard field device protocols. Interoperability and interchangeability can be ensured. Use the same tools and work procedures as before.

No Learning Curve = Smooth Change Over

Standard Industry Connections

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