Abstract
A leak sensor system for use in liquid processing equipment is disclosed. Liquid is detected by a sensing resistor whose impedance decreases dramatically in the presence of liquid. The effect of this impedance drop on the output voltage of he sensor indicates a wet or moist state which may indicate leakage from the liquid processing. A terminal resistor is in the circuit beyond the sensing resistor ro provide a warning indicator when the sensing resistor is damage or disconnected. The leak sensor system is particularly useful in centrifuge equipment, e.g., for the processing of blood.
