Triaxial piezoelectric accelerometer for vibration testing

The Endevco model 2228C rugged low-mass triaxial piezoelectric accelerometer from Meggitt Sensing Systems, is designed to suit a variety of general vibration testing requirements.

It can be used in a number of applications such as R&D, metrology, lighting systems, wireless equipment, space shuttle and solid rocket booster electronics assemblies, helicopter engines, combustion turbines and vacuum pump applications.

With a sensitivity of 2.8 pC/g, the Endevco model 2228C is designed to provide vibration measurements on three orthogonal axes with 10-32 receptacles to allow data collection from three separate output connections. These connections also offer a visual reference for the orthogonal axes being measured.

With a total package weighing just 15 grams, the accelerometer effectively minimizes mass loading on small structures and objects. Units are designed to reliably operate over a temperature range of -55°C to +177°C (-67°F to +350°F), with mounting via two-hole screw or adhesive.

The accelerometer is a self-generating device that requires no external power source for operation. Signal ground is isolated from the mounting surface of the unit. Low-noise, flexible coaxial cables are supplied for error-free operation.

Recommended accessories for use with the 2228C include the model 133 three-channel piezoelectric signal conditioner; the model 2771C remote charge converter; the model 2775B signal conditioner; model 6634C vibration amplifier; or the model 4990A multi-channel signal conditioner.
