Description
The EJA120E is a traditional-mount draft range pressure transmitter and is part of the most recent evolution of the DPharp family, the EJA-E series. It features a single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. EJA120E outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure. Other key features include quick response, remote set-up using communications and self-diagnostics.
The EJA120E is the traditional-mount Draft Range Pressure Transmitter in this series.
EJA120E features include:
- ± 0.2% Accuracy (0.09% available with /HAC option)
- ± 0.3% per 1 year Stability
- 150 ms Response Time
- Exida and TUV SIL 2/3 Certified
- Local Parameter Setting (LPS)
- True Draft Range design
Available with HART 5/7, 1 to 5 VDC HART 7 (Low Power), FOUNDATION Fieldbus, PROFIBUS PA, or BRAIN communication.
Enhance Operations: 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.
Dynamic Compensation
Compensates for process changes to improve accuracy.
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.
Increased Reliability: 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 planet.
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.
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.
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.
Simplified Maintenance: 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.
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.
Simple Troubleshooting
Local intuitive display with simple error messaging.
NE107 compliant alarms in FieldMate make troubleshooting easy.
