EJA115E Low Flow 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 EJA115E is Differential Pressure Transmitter in the series that is optimized for low flow applications with the addition of an Integral Flow Orifice (IFO).
EJA115E features include:
0.055% Square Root Output Accuracy
0.1% per 7 years Stability (DP)
Exida and TUV SIL 2/3 Certified
90 ms ~ 150 ms Response Time
Local Parameter Setting (LPS)
Available with HART 5/7, 1 to 5 VDC HART 7 (Low Power), FOUNDATION Fieldbus, PROFIBUS PA, BRAIN communication.

More Information = Found Money
Save up to 20% on CAPEX spending using our transmitter’s multi-sensing capability.
Using digital communication, one EJX110A can supply your control system with Level (Primary variable), Blanket Pressure (Secondary variable), and Sensor Temperature (Third variable)—eliminating the need for multiple transmitters.
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.
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

Yokogawa transmitters are designed to out live your planet.
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
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
