Bullet High Shock Accelerometer, Model 3086A

Dytran logo



Series 3086A/AT quartz shock accelerometers are designed to measure mechanical shock events of up to 70,000 g’s amplitude. These rugged miniature instruments feature compression design quartz seismic elements for very high natural frequency and ruggedness. Onboard miniature IC amplifiers convert the very high impedance voltage signals from the quartz crystals to a much lower impedance level which allows these instruments to drive long cables with negligible signal loss.  The output signals are directly in units of mV/g.


These series of instruments are part of Dytran’s line of IEPE instrumentation and as such, may be compatible with existing installations from other manufacturers which use similar principles.





The quartz element is mounted within the housing in an inverted position to minimize base strain effects.  The quartz crystals are tightly preloaded in place between the base and the seismic mass, with a thin metallic electrode sandwiched between them to collect the voltage signal from the crystals.  When the instrument senses acceleration into its base, the seismic mass is accelerated through the crystals accordingly.  The inertial force from the seismic mass acting upon the crystals, produces a force equal to the mass times the acceleration.  This force then squeezes or relaxes the preload on the crystals, depending upon its sense, producing a voltage analogous to the impinging acceleration input.


This signal is processed by the unity gain IC amplifier which drops the impedance level approximately 10 orders of magnitude to 100Ω. This allows the signal and constant current power to be carried over long cables with little or no loss.


The amplifier is connected to the OUTPUT/POWER pin of the top header where it can be connected to the IEPE power unit.


The inner body of the series 3086A/AT is electrically isolated from the mounting surface.  This is to eliminate annoying “ground loops” which can cause spurious signals to interfere with the measurements.
