Overview

Released in 2012, it combines the ruggedness and success of the work-horse EJA-E series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.

The EJA430E is our traditional-mount gauge pressure transmitter in the series.

EJA430E features include:

  • ± 0.055% Accuracy (0.04% Accuracy optional)
  • ± 0.1% Stability per 10 years
  • 90 ms Response Time
  • Exida and TUV SIL 2/3 Certified
  • Local Parameter Setting (LPS)

Available with HART 5/7, 1 to 5V HART 7 (Low Power), FOUNDATION Fieldbus, PROFIBUS PA, or BRAIN communication.

Digital Performance

Digital Performance

Yokogawa's DPharp digital sensor offers twice the performance and stability of the competitor's analog sensors. The DPharp uses the latest in IC Chip-style design and manufacturing technology. Analog sensors are based on older design technology. Although analog sensors are good, the modern DPharp sensor out performs them. A Yokogawa transmitter with DPharp digital sensor will give you the consistent, reliable, accurate measurement you need.

Poor Performance = Lost Money 

Signal Characterization

Signal Characterization

Signal characterization is a versatile function available on all Yokogawa pressure transmitters. The function is used to compensate the analog 4 to 20 mA output signal for non-linear applications. Such applications include tank strapping or flow measurements; but, it can be used in any application where the relationship between the pressure input and the desired output signal are known. This feature can use up to 10-points.

Greater Flexibility = Found Money 

Local Indicator

Local Indicator

All of the process variable's measured by Yokogawa's transmitter can be displayed on the easy to read local indicator. The indicator can display any of the variables measured (DP, SP, Capsule temperature); alarm codes with short text; and a sweeping bar graph to give a graphical representation of the process. Fully programmable, the indicator is customizable for your needs. Unlike competitor's transmitters, the indicator is not driven off the 4 to 20 mA analog signal, but, exist on a separate circuit. This allow the display to operate independently from the output signal, so it can indicate information that maybe more useful at the transmitter location.

More information = Found Money 

Standard Diagnostics

Yokogawa's transmitter has 40 self-diagnostic checks to ensure that everything is running smoothly within the transmitter. But, all transmitters on the market have a level self-diagnostic checks. However, Yokogawa has two that are not offered by competitors. First, the transmitter features a patented Back-check Technology that reverse checks all calculations in real-time. Second, the DPharp sensor is an active sensor. This means that the sensor is constantly supplying a signal even when the process has not changed. If the signal is lost from the sensor, the transmitter knows there is an issue. Competitor's analog sensors are passive. They do not supply a continual signal, so, is the sensor still working when there is no signal?
