Miniature Accelerometer for High Temperature Automotive and Aerospace Vibration Measurements, 3221C Series

Chatsworth, CA – October 13, 2010 – Dytran Instruments is pleased to announce the release of a new family of charge mode accelerometers designed specifically for high temperature vibration measurements of small structures. The 3221C series are ideal for automotive and aerospace applications, including flight testing and engine vibration monitoring, as well as Environmental Stress Screening (ESS) and general purpose high temperature applications.

The 3221C series are hermetically sealed using laser welds and a ceramic-to-metal sealed connector, as well as base-isolated to avoid annoying ground loop interference. Offered with a high charge output (available in 5pC/g and 10pC/g sensitivities), the 3221C series contain a piezoceramic annular shear mode accelerometer element mounted in a stainless steel housing. This type of sensing element is used in order to achieve the high resonant frequency that the 3221C exhibits (>40 kHz).

These miniature accelerometers utilize a 10-32 radial connector and a through-hole mount which allows for the sensor to be turned 360 degrees prior to securing, aiding the user during sensor installation. They are mounted with a model 6297 mounting screw (supplied). When operating the 3221C Dytran recommends the use of either the 6013A or 6019A low noise coaxial cable assemblies.
