The 3273A Series from Dytran Instruments Inc., Chatsworth, CA, are miniature triaxial IEPE accelerometers designed for modal analysis testing. The accelerometers are available in sensitivities of 10 mV/g, 50 mV/g, and 100 mV/g and have a low-end frequency response of –10% down to 0.31 Hz. Features include a laser-welded titanium design, ceramic sensing elements coupled to ultra-low-noise JFET electronics, an excellent SNR, a weight of 2.7 g, and large, laser-marked axis labels on three orthogonal faces. Applications include modal analysis, general triaxial vibration measurements, shaker control squeak and rattle, and noise, vibration, and harshness (NVH).
