Weighing 2.7 g, Series 3273A has laser-welded titanium design with ceramic sensing elements coupled to JFET electronics. Its noise floor is 0.0012 or 0.0002 Grms depending on model. Labels of axes X, Y, and Z are laser-marked in large font size on 3 orthogonal faces, which aids the user in orienting sensor. Designed for modal analysis testing, IEPE accelerometers are available in sensitivities of 10, 50, and 100 mV/g and offer low end frequency response of -10% down to 0.31 Hz.
