Conductivity Measurement in Food & Beverage Industry Clean-in-Place (CIP) Applications
Clean-in-Place (CIP) Liquid Analysis Solutions for the Food & Beverage Industry
Sanitary Conductivity Sensor Provides Accurate Measurement
Process piping and vessels used in the food and beverage industry require periodic cleaning without disassembly to remove residue from previous batches and to sanitize the equipment in place. A series of flushes with detergents, acid solutions and water is used. Since the various cleaning solutions are more conductive than the water used for flushing and final rinsing, conductivity measurement can be used to monitor the various cleaning steps and the final rinse. Sensors in these applications must have a sanitary design to ensure they do not trap residue that could decay or harbor microorganisms. The Rosemount™ 245 Sanitary Flow-Through Toroidal Conductivity Sensor is an ideal solution for food and beverage manufacturing as toroidal sensor technology seldom requires cleaning and features smooth surfaces, unlike contacting conductivity sensors.
