摘要： A sensing device and a method for sensing the presence and absence of an object in a machine using the sensing device. The sensing device generally including a sensing mechanism, a resistive element, and a control mechanism communicatively coupled to the sensing mechanism and resistive element. The sensing mechanism being coupled to the resistive element. The method comprising actuating the sensing mechanism so that it senses the location of the object. Recording the voltage across the resistive element in the control mechanism when the sensing mechanism senses the location of the object. Reactuating the sensing mechanism at least one more time to sense the location of the object. Measuring a subsequent voltage across the resistive element when the sensing mechanism is reactuated and comparing the subsequent voltage with the recorded voltage across the resistive element when the resistive element sensed the location of the object. Sending a signal to the machine when the subsequent voltage is not substantially equal to the recorded voltage.
