The accelerometer calibration station is an important tool used to verify the accuracy of piezoelectric accelerometers. Piezoelectric transducers create a voltage output when stress is applied to the material. The voltage output is read and filtered by a computer to translate accelerometer output into a component of acceleration. Proper accuracy of accelerometers will provide reliable test data for experiments which analyze the frequency of structures. The Accelerometer calibration system vibrates the accelerometers at a known frequency/magnitude. The system compares the output of the accelerometer to these known values and determines if the output meets its accuracy parameters.
