Exhibiting proven performance in extreme environments, ICP® operation of piezoelectric accelerometers provides excellent reference and stability over time. The ICP mode of operation excels in operator diverse, low signal level, long cable run, and uncontrolled environments. When one considers the myriad of ICP operation benefits for general vibration measurement use, it becomes evident that these benefits minimize uncertainties in the critical competence of vibration calibration. The following article outlines the major features that have propelled ICP vibration references to the heart of most modern vibration calibration systems.
