Meggitt Sensing Systems (San Juan Capistrano, CA) offers the Endevco model 2222C piezoelectric accelerometer, with a sensitivity of 1.4 pC/g and frequency range of 1 to 10k Hz (±1 dB). It is designed for general purpose vibration measurements of small structures or objects, such as those typically encountered with scale models, circuit boards, and disk drives. The weight of 0.14 grams (not including cable) minimizes mass loading concerns, with a shock limit that is two times that of any other accelerometer of its size and type on the market. It is a self-generating, adhesive mounted device that requires no external power source for operation. Units are ground isolated from the sensor mounting surface. A specially designed low-noise coaxial cable and sensor installation/removal tool are supplied.
