Sanitary processes have their own sets of governmental and organizational requirements and standards, the goal of which are the delivery of safe products that are unadulterated by contamination. To that end, there are special performance and construction features required for the processing equipment, piping, facilities, and anything that comes in contact with the product or its constituents at almost any stage of production.

Pressure transmitters are a common fixture of fluid processes, sanitary or otherwise. The connection of a pressure transmitter to a sanitary system will generally be accomplished via one of several recognized sanitary connectors. The connectors facilitate the maintenance of sanitary conditions in the process vessel or piping by blocking contaminants from entering the system, establishing a leak free seal at the connection, and not being a source of contamination to the process. Transmitters for sanitary applications must also accommodate CIP and SIP operations where certain chemicals or steam may be introduced to the system for cleaning or reducing bioburden. Installation of the instrument should allow for complete drainage from the connection back into the main process line or tank, while also providing good access to the instrument head for observation, maintenance, or validation.

Yokogawa provides their EJA-E series of pressure transmitters with a range of connection options, including those for sanitary systems. The DPharp sensing technology provides top flight performance and a wide variety of configuration options meet the needs of almost every modern process measurement requirement. Communication options include Fieldbus, Profibus, and HART. The HART option allows the use of Yokogawa's HART Field Communicator which facilitates and streamlines many regular setup and maintenance tasks.
