Firstly, the 3099A Series measures high shock impact up to 60 kg. As well as other high amplitude, short-duration events where high frequency “ringing” and zero shift phenomena can be a problem. Its unique miniature design incorporates a quartz sensing element. This contains a mechanical and electrical filter. Which ensures zero shift and does not corrupt your SRS plot. Quartz is a naturally poled single piezoelectric crystal. It provides better stability of the sensitivity value over time and across a wide range of operating temperatures.
Secondly, the 3099A is case isolated. This is to avoid ground loop interference and structure-borne electrical noise. The stainless-steel housing is hermetically sealed for use in wet or humid environments.
The miniature size of the sensor allows it to be mounted in spaces that are inaccessible to other types of accelerometers. Models 3099A5, A6, and A7 terminate in a 10-32 connector. Also available in multiple lengths. The 3099A also comes with a cable adapter (Model 6109) for end-users that need a different mating termination. The use of a 10-32 connector offers a user-friendly instrument that eliminates a manual assembly step prior to use. All models feature a 1/4–28 integral mounting stud.
Finally, the 3099A Series Shock Accelerometer works in a variety of application environments, including high shock metal-to-metal impact, explosive bolts, drop-shock testing of consumer electronics, stage separation testing, impact tools, and pyroshock events.
