3133D

Dytran model 3133D is a hermetically sealed, ultra-miniature triaxial IEPE accelerometer designed for high-performance vibration testing in compact and thermally demanding environments. It is part of the 3133 series and is widely used in Environmental Stress Screening (ESS), HALT/HASS procedures, modal and structural analysis, and product response evaluations.

With multiple sensitivity options ranging from 0.25 mV/g to 10 mV/g and corresponding measurement ranges up to 200,000 m/s², the 3133D is suitable for both low-g diagnostics and extreme shock applications. Its frequency response starts at 0.3 Hz and extends to 6 kHz, supported by a 35 kHz resonance frequency for clean signal fidelity across all axes.

Weighing between 0.8 g and 1.3 g and featuring adhesive mounting, the sensor is optimized for space-constrained setups where minimal mass loading is essential. Its –55 °C to 160 °C temperature range and hermetic sealing ensure reliable operation in harsh industrial and thermal environments.
