What is a Sanitary Level Transmitter?

In the pharmaceutical and food and beverage industries, measurements must take place in a way that prevents any contamination. That's why sanitary level transmitters have streamlined designs and flush fit to minimize material build-up and optimize cleaning.

Benefits of a Sanitary Level Transmitter

The EJA565E and the EJA564E sanitary level transmitters carry third-party certifications to meet hygienic and sanitary process regulatory standards. They also offer flush diaphragm technology, easy push-button display, and active temperature compensation.

What are Hygienic and Sanitary Pressure Transmitters Used For?

Hygienic and sanitary pressure transducers for Food and Beverage, Pharmaceutical, and Life Sciences applications are used to ensure that products can be produced free from biological and chemical contamination.  This requires a highly polished and flush fit design that prevents the build-up of material and allows for easy cleaning.

How Hygienic and Sanitary Pressure Transmitters Work


Level Applications Pressure Applications

Receiving tanks

Pasteurization heat exchangers

Balance tanks

Clean-in-place (CIP)

Clean-in-place (CIP)

Separation and sterilization systems

Batch reactors

Pump performance monitoring 

By providing up to 0.075% accuracy and 10:1 turndown the EJA565E transmitter allows organizations to standardize on fewer models instances, simplifying ERP systems and reducing overall material inventory.


Active Temperature Compensation

Whether due to process upsets, ambient conditions, or dosing, temperature changes can have profound impacts on traditional instrumentation. With a unique, active temperature compensation design, the EJA565E and EJA564E provide the most robust and Tank Volume Linearizationstable measurements to ensure improved process control, product quality, and safety.


Tank Volume Linearization

Digital configuration to linearize the volume with the transmitter output in the EJA565E simplifies configuration and reduces start-up time.


Easy Pushbutton Display

Easy Pushbutton Display

Expedite the commissioning and startup process with easy pushbutton displays. Make zero, span, and other configuration adjustments to the hygienic & sanitary pressure switch even without a local pressure reference source.


Flush Diaphragm Technology

Flush Diaphragm TechnologyFlush diaphragm technology reduces the build-up of contaminants that could impact food and drug safety and minimizes downtime need for cleaning pipes and vessels.


3-A Sanitary Standards, Inc. Certified

Trust that the EJA565E and the EJA564E will meet regulatory requirements with 3rd party certifications for hygienic and sanitary processes.


Eliminate O-Ring Replacements

Unlike conventional hygienic and sanitary pressure transmitters, the EJA565E and the EJA564E do not require regular replacements of O-rings. Reducing maintenance time and costs.

Industrial Applications of a Sanitary Level Transmitter  

The applications of the EJA564E Sanitary Level Transmitter include:

  • Pasteurization heat exchangers
  • Clean-in-place (CIP)
  • Separation and sterilization systems
  • Pump performance monitoring



Tank level measurements must be simple and accurate in order to maintain the milk quality, reduce waste and clean-up costs, and enable facility profitability.


Difficulties in measurement and monitoring can arise, however, when the recycled milk from the pasteurization process is introduced to the balance tank.


Yokogawa’s EJA565E Hygienic and Sanitary pressure and level transmitter presents an ideal solution to improve production throughput in a convenient and easy-to-use package. Breweries can expect an excellent return on investment. With less fluctuation in the level measurement, brewers can confidently increase their setpoints without fear of overfilling their vessels.
