Request Information
The Dytran 3133A series is a family of ultra-miniature IEPE triaxial accelerometers, weighing just 0.8 grams, and were designed to mount in spaces inaccessible to other types of accelerometers.

Available in three different models, with choice of 2, 5 or 10 mV/g sensitivity, design of the Dytran 3133A series incorporates shear sensing elements with integral electronics, packaged in a robust, lightweight, welded titanium cube, with a three-foot integral cable terminating to a 4-pin connector and adhesive mounting capabilities. The cable is designed to mate with several different types of Dytran extension cables.

These ultra-miniature teardrop sensors are capable of operating at temperatures up to +300°F (+149°C). Series model 3133A1 is the world’s smallest triaxial IEPE accelerometer with 10 mV/g sensitivity.
