Yokogawa EJX115A Low Flow Transmitter

The EJX-A series is Yokogawa’s premium performance line of DPharp transmitters. Released in 2004, it offers the performance and stability needed in demanding applications. The EJX-A series performance makes it the thoroughbred of the DPharp family of pressure transmitters.

The EJX115A is Differential Pressure Transmitter in the series that is optimized for low flow applications with the addition of an Integral Flow Orifice (IFO).

EJX115A features include:

0.04% Square Root Output Accuracy
0.1% per 10 years Stability (DP)
90 ms ~ 150 ms Response Time
Exida and TUV SIL 2/3 Certified
Local Parameter Setting (LPS)

Enhance Operations

Plants run better with Yokogawa pressure transmitters.

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.

More Information

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.

Increase Reliability

Yokogawa pressure transmitters help plants run longer.

Rugged Construction

Ruggedness = Reliability

Reduce failures in the field by 200%.

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.

Simplify Maintenance

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
