EJA130E Differential 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 EJA130E is a differential pressure transmitter designed to work in a high static pressure environment.

The EJA130E is designed to measure accurately, transmit quickly, and do it reliably over time.

  • Accurately: ± 0.055% Accuracy
  • Reliably: ± 0.1% Stability per 10 years
  • Quickly: 150 ms Response Time

Plants run better with Yokogawa pressure transmitters.

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.

 


 

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

 


 

More Information

Save up to 20% on CAPEX spending using our transmitter’s multi-sensing capability.

Using digital communication, one EJA130E can supply your control system with Level (Primary variable), Blanket Pressure (Secondary variable), and Sensor Temperature (Third variable)—eliminating the need for multiple transmitters.

More Information = Found 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 Back-check Technology is reverse checking all calculations in real-time.

Good Diagnostics = Less Surprises

Yokogawa pressure transmitters help plants run longer.

Yokogawa's DPharp active sensor, patented back check diagnostics, and rugged construction allow users to run their plants safer and with less downtime.


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

Over 6 million DPharp transmitters are installed worldwide.

Less Downtime = Making Product

 

 

 

 

 


 

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.

Inerently 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.

 

Routine maintenance is easier with Yokogawa pressure transmitters.

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


 

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

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

 

 

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

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.

Reduce stock.

 


 

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.

Communicators

Yokogawa manufactures a communicator for your needs. Yokogawa communicators are available for BRAIN Protocol, HART Protocol, FOUNDATION Fieldbus, PROFIBUS PA, ISA100, or MODBUS. All our communicators are compatible with Yokogawa products as well as other products on the market.

Indicators

Yokogawa offers a range of loop powered and FOUNDATION Fieldbus remote indicators that can be used to locally monitor data from field instruments installed in difficult to access locations.

Pressure Calibrators

The Yokogawa CA700 Portable Pressure Calibrator uses the same DPharp sensor technology as our EJA-E and EJX-A series pressure transmitters. It provides an accurate and efficient calibration and verification tool for any pressure transmitter or other type of field device.

Communication Converters

Yokogawa offers communication converters by Moore Industries to convert secondary HART protocol variables to a 4 to 20 mA analog signal or all the HART variables to MODBUS RTU.
