EJA210E Flange Mounted Differential Pressure Transmitter

Published on : Tuesday 30-11--0001

The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family of pressure transmitters. 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 EJA210E is the Flange-mount Liquid Level Transmitter in the series.

EJA210E features include:

• ± 0.075% Accuracy
• ± 0.1% per 1 year Stability
• 120 msec Response Time
• Exida and TUV SIL2 / SIL3 Certified
• Signal Characterizer for the 4 to 20 mA output
• Local Parameter Setting (LPS)

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.

Poor Performance = Lost Money

More Information

• Yokogawa's DPharp sensor can supply you greater insight into your process. One transmitter can supply your control system with Tank Level (Primary Variable), Blanket Pressure (Secondary Variable), and Sensor Temperature (Third Variable) - no need for multiple devices.

More Information = Found Money

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
