3145A

Dytran model 3145A is a miniature, hermetically sealed uniaxial IEPE accelerometer engineered for precision vibration measurements in environments where mass loading must be minimized. Designed for Environmental Stress Screening (ESS), modal and structural analysis, and general-purpose vibration control, the 3145A combines high sensitivity with compact form factor.

With a sensitivity of 100 mV/g and a measurement range of 500 m/s², it is optimized for low-amplitude vibration diagnostics. The sensor operates across a frequency range of 1 Hz to 7 kHz, supported by a high resonance frequency of 45 kHz for clean signal fidelity. Its stud mounting ensures secure mechanical coupling, while the hermetic seal protects against environmental contaminants.

Weighing just 2.3 g, the 3145A is ideal for applications where sensor mass could influence system dynamics, such as lightweight structures, aerospace components, and precision assemblies.
