The Dytran series 3274 is an ultra miniature high frequency IEPE accelerometer with TEDS capabilities.

Units have an overall height of just 0.24–inches (6.1–millimeters), weigh just 2 grams, and are ideal for the measurement of shock and vibration of very small, lightweight objects such as printed circuit boards and board mounted components.

Offered with a sensitivity of 5 mV/g, 10 mV/g and 25 mV/g the series 3274 features a quartz shear sensing element, packaged in a lightweight, teardrop titanium housing. Designed for adhesive mount, the Dytran series 3274 has an upper frequency response of 10,000 Hz. Due to their low mass and high crystal stiffness, units have a resonant frequency of >40 kHz, allowing them to be used to measure high frequency vibration with very little error.

The series 3274 utilizes a specially designed 3–56 coaxial connector, mating with a 3–foot (0.9–meter) replaceable coaxial cable and terminating to a 10–32 jack. Units are hermetically sealed for reliable operation in high humidity environments, as well as case isolated to avoid EMI/ground loop interference.

Features:

  • Titanium
  • Hermetic
  • IEPE
  • Case isolated
  • Ultra miniature teardrop design
  • TEDS capabilities

Applications:

  • Environmental Stress Screening (ESS)
  • Modal analysis
  • Product response testing
  • High frequency vibration applications
