EJA210E Flange Mounted Differential Pressure Transmitter

The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family of pressure transmitters. Released in 2012, 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)

Explore how the EJA210E can help you Boost your bottom line.

Plants run better with Yokogawa liquid level transmitters.

At it's heart, Yokogawa's Liquid Level Transmitter with DPharp digital sensor offers the performance and device intelligence needed to get greater insight into your process.


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


Rugged Construction

Ruggedly constructed liquid level transmitter can help your plant reduce failures. Yokogawa's liquid level transmitters have construction features that are designed to allow it to outlive your plant. Four-bolt pressure retaining design, Teflon coated 316L stainless steel flange gasket, and dual seal certified to ANSI/ISA 12.27.01 - all design features to extend the life of the transmitter.

Ruggedness = Reliability

Ruggedness = Reliability


Inherently Safe

All Yokogawa pressure transmitters are designed and certified to IEC61508:2010 Parts 1 through 7 and IEC61511:2004 Parts 1 through 3. They are certified for single transmitter use in SIL 2 safety applications and dual transmitter use in SIL 3 safety applications with no special option required. With Yokogawa EJA-E transmitters, no longer will you have to maintain two seperate inventories - one for production applications and one for safety applications.

Inherently Safe = Reliability

Routine maintenance is easier with Yokogawa liquid level transmitters.

Extended Calibration Intervals

Yokogawa EJA-E series pressure transmitters have a long-term stability under all operational conditions. As you gain experience with these transmitters, you will be able to extend the time between calibration checks.

Quicker Maintenance = Less Downtime

Interval Between Calibration Checks


Multiple Communication Options

Yokogawa offers several platforms to communicate to your transmitter.
FieldMate is a PC based communication platform that can communicate with your transmitter and manage your entire instrument inventory.
FieldMate HHC is a traditional hand-held platform that allows you to take that information into the field.
Forgot your HHC? No problem. The LPS feature on the transmitter allows you to update 9 parameters without the use of an HHC.

Quicker Maintenance = Less Downtime

Flushing Ring

A flushing ring a round device that is place between the diaphragm seal and the process connection. The device has two 1/4-inch ports that can be used to run a flushing solution across the face the seal to clean it. If you need a different size port, Yokogawa also offers Flushing Rings supplied by a global partner WIKA.


Yokogawa manufactures a communicator for your needs. Yokogawa communicators are available for BRAIN Protocol, HART Protocol, FOUNDATION Fieldbus, PROFIBUS PA, ISA100, or Modbus. All out communicators are compatible with Yokogawa products as well as other products on the market.


Yokogawa offers a range of loop powered and FOUNDATION Fieldbus remote indicators that can be used to locally monitor data from field instruments installed in difficult to access locations.
