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 EJX130A is the traditional-mount high-static Differential Pressure Transmitter in the series.
The EJX130A is designed to measure accurately, transmit quickly, and do it reliably over time.
- Accurately: ± 0.04% Accuracy
- Quickly: 150 ms Response Time
- Reliably: ± 0.1% Stability per 15 years
Details
Plants run better with Yokogawa pressure transmitters.
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.
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 EJX130A 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 Patented Back-check Technology is reverse checking all calculations in real-time.
Good Diagnostics = Less Surprises

How Are Pressure Transmitters Built?
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.

Independent Verification
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.
What Are the Benefits of Pressure Transmitters?
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
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.
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.
