Ultra Low Noise Triaxial Accelerometer for Modal Analysis, 3333A Series
Chatsworth, CA - Dytran Instruments, Inc. has just released a new series of miniature triaxial accelerometers, weighing just 2.3 grams. The 3333A series was designed for modal analysis testing and general purpose vibration testing, and has a robust, laser welded titanium design which includes ceramic sensing elements coupled to ultra low noise JFET electronics.
The 3333A series is unique in that it features an ultra miniature 4-pin connector. Compared to the industry standard 4-pin connector (1/4-28 thread size), the connector on the 3333A series is approximately 20% smaller in size. This substantial size difference allows for a more flexible, lighter weight cable, a smaller diameter for the connector, and also contributes to the smaller size of the sensor itself.
With a low end frequency response of -10% down to 0.31 Hz, the 3333A series accelerometers offer excellent phase response at low frequencies. It also features an excellent signal to noise ratio.
The 3333A series are available in sensitivities of 10 mV/g, 50 mV/g and 100 mV/g. Featuring a hermetic seal and adhesive mount, this triaxial IEPE accelerometer weighs only 2.3 grams. Its titanium housing contributes to its lightweight, which provides for minimal mass loading of the test article.
Designed for modal analysis applications, the 3333A series accelerometers are also ideal for the following applications: general purpose triaxial vibration measurements, shaker control, Squeak & Rattle, and Noise, Vibration & Harshness (NVH).
