Piezoelectric accelerometers for general-purpose vibration test introduced by Meggitt
March 9, 2012
SAN JUAN CAPISTRANO, Calif., 9 March 2012. Meggitt Sensing Systems in San Juan Capistrano, Calif., is introducing the Endevco model 2224C series piezoelectric accelerometers for general-purpose vibration test and measurement of smaller structures and components in aerospace, electronics, industrial, automotive, and laboratory applications.
The Endevco 2224C vibration sensor comes with a 12 pC/g sensitivity, and features a 10-32 top connector for use in space-constrained environments. The accelerometers use Meggitt's proprietary piezoelectric crystal technology operating in annular shear mode.
Sensor construction allows for low base strain sensitivity, high resonance frequency, and solid output stability over time, Meggitt officials say. Signal ground connects to the outer case of the unit and, when used with isolated mounting stud, is electrically case isolated from ground.
A low-noise Endevco model 3090C-120 coaxial cable is supplied, along with a 10-32 mounting stud and installation wrench. Optional accessories are sold separately and include the Endevco model 2771C-XX remote charge converter; model 2775B benchtop signal conditioner; the model 133 three-channel piezoelectric signal conditioner; or the model 4990A (Oasis) rack mounted signal conditioner and power supply.
Isolation mounts and magnetic mounting bases also are available. For more information contact Meggitt Sensing online at www.meggittsensingsystems.com.
