With a broad frequency response of 0.3 Hz to 10,000 Hz and a high sensitivity of 100 mV/g, the Model 3263M8 miniature triaxial accelerometer from Dytran Instruments is suitable for modal analysis, NVH (noise vibration and harshness) studies, environmental stress screening, and general-purpose vibration measurement. The device offers a full-scale range of ±50 g in each axis and linearity of 1% FS maximum.

The Model 3263M8 comes in a lightweight titanium alloy housing and features a single 4-pin connector and a 4-40 tapped hole. To aid in orientation, the X, Y, and Z axes of the sensor are laser-marked in a large font size on three orthogonal faces. The IEPE (Integrated Electronics Piezo Electric) accelerometer, which weighs 5.6 grams and is just 0.48x48 in., has a supply current range of 2 mA to 20 mA (each axis) and a compliance supply voltage range of 18 VDC to 30 VDC (each axis). Typical output impedance is 150 ohms. The hermetically sealed device operates over a temperature range of –60°F to +180°F.
