Emerson introduces new sanitary measurement transmitters and regulators for life sciences applications
The Rosemount 4500 sanitary pressure transmitter delivers superior performance and cost savings for sanitary pressure applications. The transmitter best-in-class SIP/CIP performance improves throughput by reducing temperature induced errors; improved stability reduces maintenance costs; and AMS compatibility simplifies FDA compliance.
Part of the new offering of industry-specific Rosemount pressure transmitters, the 4500 is designed exclusively for the needs of the life sciences industry. The transmitter features both EHEDG and 3-A approvals and provides high quality electro-polished wetted surfaces, hygienic connections, and a smooth, crevice free housing design interfacing to the surrounding clean-room, so that it can be wholly within a designated clean room area.
Similarly with Rosemount temperature transmitters, as much attention is paid to the hygienic design of the external housing, as was previously paid to the wetted surfaces. Engineering and production of these instruments is to EHEDG approval from the European manufacturing and technology centres within the Emerson organisation.
Rosemount temperature sensors are available as in-line systems, in which the thermowell is part of a straight or elbow pipe, designed free of dead-pockets, ensuring efficient CIP and SIP processes and allowing the exchange of a measurement sensor without disturbing the process integrity or continuity.
The Rosemount Analytical Model 245 conductivity sensor is a toroidal flow-through pipe section design, suitable for both clean-in-place and steam-in-place installations. The sensor is available in four different line sizes ranging from half an inch to two inches. Manufactured with FDA-compliant wetted materials (316L Stainless Steel, EP and unfilled-PEEK) the Model 245 meets all sanitary standards. Tri-clamp end connections provide sanitary and convenient process installation.
The sensor uses a non-contact conductivity measurement, avoiding all fouling or corrosion, so is suitable for fibrous or sticky liquids or aggressive cleaning chemicals, and can be used with a temperature sensor to monitor composition or concentration of flowing liquids.

Several designs of Fisher pressure regulators are also designed to meet sanitary requirements, such as the Fisher SR5 pressure and SR8 back-pressure regulators. These have 316L stainless steel body and wetted parts, and a 316 stainless steel spring case. All wetted parts are mechanically polished to a 20Ra Microinch finish, and then electro-polished. The Tri-Clamp end connections are matched by a quick disconnect bonnet using a Tri-Clamp sealed joint. Such regulators are frequently used in Water-for-Injection (WFI) and clean steam applications.
Also essential on pharmaceutical plants are gas blanketing systems to control the inert gas atmospheres in product and ingredient or solution storage vessels. Fisher regulators have been engineered in stainless steel and FDA/EHEDG approved materials for use in the control of suitable tank blanketing systems.
