This white paper examines various types of state sensors and their functional use in pinch valves for advanced system development. Many systems today, including medical and biopharmaceutical applications, require precise control and monitoring of a variety of fluids during operation. Systems can employ several methods to control fluid. Solenoid and pneumatic pinch valves, used in conjunction with flexible tubing, offer a simple approach to non-wetted fluid control. At the most fundamental level, various types of sensors can be incorporated into pinch valves to provide feedback showing the physical, open or closed, state of the valve. This paper covers both the basics of state sensing as well as advanced applications to detect the presence of tubing.
