Field of application
Smartec CLD18 is the cost-effective solution for all applications in beverage plants where small tubes are used and where the toroidal measurement is used as a switch function. The combination of a transmitter and a sensor is interference-free, easy-to-use and features a hygienic design that protects your products and processes from contamination. Smartec CLD18 ensures the Overall Equipment Effectiveness (OEE) of your plant thanks to fast and reliable CIP and optional IO-Link protocol.
The hygienic Smartec CLD18 measures toroidal conductivity in beverage applications:
Control of CIP processes in the return channel
Concentration control in remaking of CIP cleaning agents
Product monitoring in pipe systems, bottling plants
Beer - Push water interphase
Beer - Water cut for brewing lines
Leakage monitoring
It features the following protocols and interfaces:
0/4...20mA
IO-Link (optional)
Benefits
