Think Top :
Concept :
Think Top®Basic is a uniform modular control unit that consists of a proven no-touch, set-and-forget sensor system with light-emitting diodes (LEDs) , solenoid valves and valve control sensor board for connection to any PLC (Programming Logic Controller) system with one of the two interfaces; Digital and AS-Interface.Think Top offers a solution for Alfa Laval butterfly, single-seat and Mixproof valves and is designed for use in the dairy, food and beverage, and bio pharm industries; Think Top provides real-time information about valve operating status 24/7 while helping to improve production performance and secure traceability.
Working principle :
Think Top is an automated control unit that can befitted with up to three solenoid valves and who convert the electrical PLC and sensor signals into mechanical energy to open or close the air-operated valve, using the physical stimulus of an indication pin mounted on the valve stem. Think Top Basic fits onto all Alfa Laval hygienic actuators equipped with mushrooms. Installation is straightforward; no special expertise, adapters or tools are required. To initiate manual setup,simply press the push-button startup sequence.
