Tiny Accelerometer weighs just 0.2 grams.

Dytran Instruments have just released a new ultra-miniature accelerometer which weighs just 0.2 grams. This sensor is ideally suited in applications where the additional mass of the monitoring device could effect the test conditions.

Even though the 3224A2 sensor is tiny, it has a robust construction with a welded titanium housing which is hermetically sealed. The sensor is ideal for tests involving environmental stress screening, printed circuit board vibration measurements, mechanical shock applications and general-purpose vibration monitoring where space is at a premium.

The device has integral electronic circuitry providing a sensitivity of 2mV/g and can operate at temperatures from -51°C to 148°C. It is designed for adhesive mounting and offers a frequency response up to 10kHz.

It uses a quartz sensing element in a planar shear mode which helps to reduce base strain effects, thermal transients response and thermal coefficient sensitivity.
The integral lightweight coaxial cable is almost 1 metre long and terminates in a 10-32 connector for easy lead wire extension.
