These Quick-Select pressure modules are available for gauge, differential and compound measurement requirements. The variable-capacitance sensing element in the AQS-1 incorporates a micromachined silicon diaphragm. Silicon provides optimum repeatability with minimal hysteresis. The sensor is extremely stable, since the sputtered metal capacitance plates are molecularly bonded to the silicon. This design allows for the elimination of epoxies and other types of bonding and adhesive agents from the sensor assembly. The AQS-1 sensor is also extremely rugged. It can withstand extreme overpressure without significant error or calibration offset. In addition, the sensor is capable of withstanding significant shock and vibration without damage or loss of measurement output integrity.
