EJX120A Draft Range Differential Pressure 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 EJX120A is the traditional-mount Draft Range Pressure Transmitter in the series.

EJX120A features include:

  • Accurately: ± 0.09% Accuracy
  • Reliably: ± 0.15% per 1 year Stability
  • Quickly: 150 ms Response Time

Explore how the EJX120A 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.

Plants run better with Yokogawa pressure transmitters.


Digital Performance

Installed performance 2x better using all digital DPharp pressure sensor.

Yokogawa’s digital sensor provides superior performance and stability compared to analog sensors.

Poor Performance = Lost Money


Standard Diagnostics

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.

Good Diagnostics = Less Surprises

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

Reduce failures in the field by 200%.

Yokogawa transmitters are designed to out live your plant.

Ruggedness = Reliability


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 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

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.

Inherently Safe = Reliability

 


 

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.

.

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

Routine maintenance is easier with Yokogawa pressure transmitters.


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

Calibration Interval (2018) (W=396;H=249)

 


 

Multiple Communication (2018) (W=387;H=274)

Multiple Communication Options

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

 


 

Simple Troubleshooting

Local intuitive display with simple error messaging.

NE107 compliant alarms in FieldMate make troubleshooting easy.

Save time, Save money

 

 

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
