The 3273A series, offered by Dytran Instruments, are miniature triaxial accelerometers designed for modal analysis testing. This series feature a robust, laser welded titanium design which includes ceramic sensing elements coupled to ultra low noise JFET electronics.

With a low end frequency response of -10% down to 0.31 Hz, the 3273A series accelerometer offers excellent phase response at low frequencies. It also features an excellent signal to noise ratio.

The 3273A series accelerometers are available in sensitivities of 10 mV/g, 50 mV/g and 100 mV/g. Featuring a hermetic seal, adhesive mount and a single 4-pin connector, this triaxial IEPE accelerometer weighs only 2.7 grams. Its titanium housing contributes to its lightweight, which provides for minimal mass loading of the accelerometer on the test article.

This family of accelerometers is unique in that the labels of the axes X, Y and Z are laser marked in a large font size on three orthogonal faces, which aids the user in orienting the sensor.

The 3273A series is available as the 3273AT series and features IEEE 1451.4 TEDS.

In addition to being offered with an adhesive mount, the 3273A series is available with a stud mount. Model 3273M2 features a 10-32 stud mount and 100 mV/g sensitivity.

Designed for modal analysis applications, the 3273A series accelerometers are also ideal for the following applications: general triaxial vibration measurements, shaker control, Squeak & Rattle, and Noise, Vibration and Harshness (NVH).
