Compliance to international quality standards (ISO 9000) has heightened awareness of calibration and traceability. This emphasis has focused more attention on the fields of metrology and calibration, creating both new concerns and opportunities for those involved in all aspects of test and measurement activities including vibration transducers such as accelerometers and velocity pickups. In addition to a general awareness of the need to calibrate accelerometers and velocity pickups, there is a growing special interest in very low frequency and high frequency calibrations. MB Dynamics has developed a system that allows accurate calibrtion of vibration transducers form 0.25 Hz to 11,000 Hz using a reference accelerometer, a more affordable alternative to lasers.
