Common in the Life Sciences and Food & Beverage industries are clean-in-place (CIP) operations to effectively clean the interior surfaces of production process piping, vessels and other inline assets before the next batch is run.

This short, 2:10 YouTube video, Effective Conductivity Measurement in Clean-in-Place Applications, highlights the importance of extremely tight measurement and control to avoid costly waste and contamination.

Conductivity measurements help to analyze and monitor costly detergents, caustics and purified water to optimize their efficient use. Rosemount contacting

The Rosemount 403 contacting conductivity and Rosemount 225 Toroidal conductivity sensor work with the Rosemount 56 dual-channel transmitter provides a conductivity sensing system that accurately measures and monitors the clean-in-place process.

The toroidal inductive, non-contacting sensor complies with 21 CFR 177 and 3-A sanitary standards. It uses two toroidal transformers that are isolated from the process. One toroid acts as an emitter and the other as a receiver. The emitter toroid produces an electric current in the process solution that induces a reduced current in the receiver toroid. The strength of that induced current is directly proportional to the conductivity of the solution.

This inductive technology enables accurate measurement across a wide range of environments from clean water to the high conductivity fluids. The Rosemount 403 contacting conductivity sensor provides quick response and accurate measurement of the flush water.
