3143M

Dytran model 3143M is a rugged, hermetically sealed triaxial IEPE accelerometer designed for airborne vibration testing, modal and structural analysis, and NVH diagnostics in aerospace and automotive applications. With a fixed sensitivity of 10 mV/g and a tight ±5% tolerance, it delivers consistent and accurate measurements across all three axes.

The sensor operates within a frequency range of 1.6 Hz to 5 kHz, supported by a 25 kHz resonance frequency for clean signal response. Its measurement range of 5000 m/s² makes it suitable for general-purpose vibration monitoring, while the center bolt mounting ensures secure mechanical coupling in dynamic environments.

With an exceptionally wide operating temperature range from –195 °C to 120 °C, the 3143M is ideal for extreme thermal conditions, including cryogenic and high-altitude testing. Its 50 g construction balances robustness with precision, making it a reliable choice for flight testing, space vehicle evaluation, and structural integrity assessments.
