Abstract
A pneumatic monitoring system for a magnetic tape drive includes a single sensor which includes a differential pressure transducer. Points in the tape drive to which vacuum is applied are coupled to one side of the sensor and points in the tape drive to which pressure is applied are coupled to the other side of the detector. The sensor produces an analog voltage representing the state of the pneumatic system. It is digitized and applied to a microprocessor which compares the sensor voltage to present ranges for calibrated conditions of the tape drive. If the sensed voltage is outside of these ranges, error conditions are indicated.
