The EJX210A is a Flanged-mounted Liquid Level Transmitter. Featuring DPharp digital sensor technology, it offers the performance and device intelligence needed for greater process insight.


What Are the Benefits of a Liquid Level Transmitter?

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


How to Reduce Total Cost of Ownership?

Yokogawa's DPharp Inherently Safe Design, Proven Technology, and Rugged Construction allow users to run their plants safer and with less downtime.

The EJX-A series is Yokogawa's premium performance line of DPharp transmitters, offering the performance and stability needed in demanding applications. The EJX-A series performance makes it the thoroughbred of the DPharp family of pressure transmitters.

The EJX210A is the flange-mount Liquid Level Transmitter in the series.

The EJX210A features include:

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

Explore how the EJX210A can help you Boost your bottom line.

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.

Less Downtime = Making Product

Proven Technology

Starting with a clean sheet of paper, Yokogawa developed in the early 1990s a completely new pressure sensing technology - the DPharp sensor. Yokogawa made a large commitment of resources and money in its development. That dedication paid off. Now there are over 9 million installed Yokogawa transmitters and calibrators worldwide using this technology.

SIL 2 Certification (2018) (W=400;H=285)

Inherently Safe

All Yokogawa EJX-A series pressure transmitter 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 rated safety applications and dual transmitter use in SIL 3 rated safety applications with no special option required. With Yokogawa EJX-A transmitters, no longer will you have to maintain two separate inventories - one for production applications and one for safety applications. How much will that save your company? The certificates are available under the "Download" tab above.

Inherently Safe = Reliability

For Yokogawa, safety should never be an option.


Routine maintenance is easier with Yokogawa liquid level transmitters.

Efficient and effective maintenance through Extended Calibration Check Intervals, Standard Communication Protocols, and Multiple communication Options.

Extended Calibration Check Intervals

Yokogawa EJX-A series pressure transmitters have a long-term stability of ±0.1% per 7 years under all operational conditions. As you gain experience with these transmitters, you will be able to extend the time between calibration checks. Long-term this can help reduce your maintenance cost by up to 33%. Spend your time where it is needed.

Quicker Maintenance = Less Downtime

Standard Communication Protocols

Yokogawa transmitters support all industry standard field device communication protocols. Interoperability and interchangeability can be ensured. Use all the same tools and work procedures as before. Yokogawa transmitters are available with analog 4 to 20mA signal with either BRAIN® digital protocol or HART® digital protocol; Low Power analog 1 to 5 VDC with HART® digital protocol; or all digital FOUNDATION® Fieldbus or PROFIBUS® PA protocol. 

No Learning Curve = Smooth Change Over

Multiple Communication Options

Save Time, Save Money. Yokogawa offers the FieldMate / LPS platform to help you communicate and track your pressure transmitters. FieldMate is a Windows based communication suite that can be loaded onto a standard PC, laptop, or tablet computer. It can assist you in managing your entire instrument inventory. FieldMate HHC is a traditional hand-held communicator that allows you to communicate with transmitters in the field. If you forget your HHC, the LPSfeature of your Yokogawa transmitter allows you to update 9 parameter without the 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.

Remote Indicators

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.




In today’s tightening orange juice market, facilities must improve efficiency to deliver high-quality products. With that goal in mind, a leading U.S. juice and citrus processor uses or sells each part of the orange. Nothing goes to waste. In the drive to improve efficiency, the juice and citrus products producer needed a reliable partner to help determine ways to reduce maintenance costs and deliver high returns. The producer selected Yokogawa products such as the EJAC80E Diaphragm Seal System with DPharp sensor technology for level control and monitoring, ADMAG AXG magnetic flow meters (magmeters) for flow measurement, and FLXA402 analyzers for pH and conductivity monitoring. 

Yokogawa diaphragm seal systems are available with an optional Flushing Ring.  A flushing ring is metal donut-shaped ring installed between the seal and the customer process connection. It is a wetted part. The ring has a port(s) that can be use...
