Abstract
A pinch valve configuration may include a pinch valve comprising a valve body, a valve plunger, and a fluidic tubing pinch passage defined between a tubing seat of the valve body and an operative end of the valve plunger. The pinch valve configuration may further include a Hall effect sensor assembly comprising a stationary element anchored to the valve body and a motive element anchored to the valve plunger. The pinch valve configuration additionally includes a failure prediction module in communication with the Hall effect sensor assembly. The failure prediction module is programmed to process an output signal of the Hall effect sensor assembly as a displacement reading, to compare the displacement reading with a failure prediction threshold, and to generate a failure prediction signal from the comparison of the displacement reading with the failure prediction threshold.
