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.

The Rosemount 1066 Single Channel Transmitter supports continuous measurement of one liquid analytical input - pH sensor, conductivity sensor, chlorine sensor, dissolved oxygen sensor or ozone sensor. The design supports easy internal access and wiring connections. The large display gives excellent visibility for live measurements and displayed parameters. Conveniently, live process values are always displayed during programming and calibration routines.
- Fast and easy installation using Quick Start programming
- Intrinsically Safe FM, CSA, and ATEX/IECEx Hazardous Location Approvals
- Visibility of process parameters by utilizing HART® or FOUNDATION™ Fieldbus digital communications
Power Supply
Supply voltage at the transmitter terminals should be at least 12.7Vdc. Power supply voltage should cover the voltage drop on the cable plus the external load resistor required for HART® communications (250 Ω)
