Dytran Instruments 3099A Series high shock accelerometers

Dytran Instruments has released the 3099A IEPE Series of mechanically and electrically filtered high shock accelerometers, available in a variety of measurement ranges.

The series measures high shock impact up to 60 kg and other high amplitude, short-duration events where high-frequency ‘ringing’ and zero shift phenomena can be a problem. Its miniature design incorporates a quartz sensing element with a mechanical and electrical filter so that zero shift does not corrupt the SRS plot. Quartz, a naturally poled single piezoelectric crystal, provides stability of the sensitivity value over time and across a wide range of operating temperatures.

The family of sensors is case isolated 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 and are offered in multiple lengths. The series also comes with a cable adapter (Model 6109) for users who 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.

The series 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.
