Reference Calibration Accelerometer Model 3038A
The Dytran model 3038A is a back–to back calibration accelerometer designed to mount on a miniature dynamic shaker and is used to calibrate other (TEST) accelerometers which are attached to its upper mounting surface. It offers a convenient means of determining the sensitivity and frequency response characteristics of unknown acceleration, velocity, and displacement sensors. A vibration laboratory already equipped with an electrodynamic shaker and control system can easily incorporate use of the series 3027 to accomplish in–house NIST traceable calibrations. Model 3038A offers 10 mV/g sensitivity, and mounts to a shaker head via a 10–32 tapped hole.
Back-to-back comparisons with the double-ended calibration standard accelerometers available in the series require the test accelerometer to be mounted directly onto the top mounting surface of the calibration standard and the coupling pair driven at a variety of frequencies and amplitudes using a motorized shaker system. At each test frequency, the amplitude is set, and the corresponding output is read from the test accelerometer. The user needs to provide cables, power supply units and an electric vibrating screen system to form a complete measurement system. The 3038A is used for low-frequency, low-g-level measurements.
