presents the Endevco 2911 shakers designed specifically for calibrating accelerometers.
Used to calibrate accelerometers and velocity pick-ups, the Endevco 2911 shaker features a high performance beryllium armature with a 10mm stroke displacement, and a unique air bearing suspension system. The output of the accelerometer or any inertial device under test is compared with the output of the integral Endevco primary vibration standard accelerometer.
The 2911 shaker performs precise sensitivity and frequency response calculations at frequencies up to 20k Hz, and resonant frequency searches up to 40k Hz, all with virtual absence of waveform distortion and transverse motion. The Endevco 2911 shaker, combined with the Endevco Automated Accelerometer Calibration System (AACS), provides a complete automated calibration system utilising advanced software and signal conditioning that maximise the use and capability of the shaker.
Meggitt Sensing Systems, the manufacturer of the Endevco shaker recommends the use of Model 2270M8 transfer standard accelerometer as a means of maintaining the calibration of the 2911 shaker at the user’s facility. The 2270M8 accelerometer has been specifically developed for back-to-back primary standard accelerometers.
Bestech Australia provides complete sales and service support for all Meggitt – Endevco accelerometers and matching calibration equipment for their customers throughout Australia.
