Our Main Business on :EJA EJX… All the Yokogawa Pressure Transmitter we sell Made in Japan! 100% Original!
Plants run better with Yokogawa pressure transmitters.
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.
Compensates for process changes to improve accuracy.
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.
Easy to read indicator provides all the information you need.
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 pressure transmitters help plants run longer.
Ruggedness = Reliability
Reduce failures in the field by 200%.
Yokogawa transmitters are designed to out live your planet.
Proven in Use
Less Downtime = Making Product
Over 6 million DPharp transmitters are installed worldwide.
Reliability verified independently by third party industry experts.
Inherently Safe Design
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.
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
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.
Save time, Save money
Local intuitive display with simple error messaging.
NE107 compliant alarms in FieldMate make troubleshooting easy.
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.
For Yokogawa, safety is never an option.
No Learning Curve
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
The EJX115A requires a review of process data to determine the correct IFO bore to supply with the transmitter. Contact your local Yokogawa representative to assist.
