EJA440E Traditional-mount High 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 EJA440E is our traditional-mount high gauge pressure transmitter in the series.

EJA440E Standard features include:

  • ± 0.055% Accuracy
  • ± 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 5 VDC HART 7 (Low Power), FOUNDATION Fieldbus, PROFIBUS PA, or BRAIN communication.

Explore how the EJA440E can help you Boost your bottom line.

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

Plants run better with Yokogawa pressure transmitters.

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.

Quicker Maintenance

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.

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

Safety as Standard

Reduce stock.

No need to stock separate inventory for safety and non-safety applications. With safety as a standard, Yokogawa transmitters can be used for either application.

For Yokogawa, safety is never an option.

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.
