Zusammenfassung:	Methods and apparatus to test acoustic emission sensors are disclosed herein. An example apparatus includes a process control device, an acoustic emission sensor coupled to the process control device, where the acoustic emission sensor detects an operational condition of the process control device, and a piezoelectric tuning fork acoustically coupled to the acoustic emission sensor to test the operational condition of the acoustic emission sensor.
