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:
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.
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.
Compensates for process changes to improve accuracy.
Easy to read indicator provides all the information you need.
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.
Ruggedness = Reliability
Reduce failures in the field by 200%.
Yokogawa transmitters are designed to out live your planet.
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.
Less Downtime = Making Product
Over 6 million DPharp transmitters are installed worldwide.
Reliability verified independently by third party industry experts.
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.
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.
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.
Reduce maintenance cost by 33%.
Improved long-term stability extends calibration intervals. Spend your time where it is needed.
Quicker = Less Downtime
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.
Save time, Save money
Local intuitive display with simple error messaging.
NE107 compliant alarms in FieldMate make troubleshooting easy.
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
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 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
Process connections designed to meet IEC61518 ensure you will not meet proprietary manifolds or accessories that limit your design choices.
