Model 2226C Piezoelectric accelerometer Features • NEW! 2226C-R available as replacement sensor • Light weight • High temperature to +177°C • Adhesive mounting • Top connector • Vibration measurement on small structures The Endevco® model 2226C is a miniature, adhesive mounting piezoelectric accelerometer designed specifically for vibration measurement on small structures and objects. The transducer features a topmounted 10-32 receptacle for installation convenience in limited space. Its light weight (2.8 gm) effectively minimizes mass loading. The accelerometer is a selfgenerating device that requires no external power source for operation. The model 2226C features Endevco’s Piezite® type P-8 crystal element operating in annular shear mode. This sensor exhibits excellent output sensitivity stability over time. A low-noise, flexible, coaxial cable is supplied for error-free operation. This device is typically used for small package testing and general adhesive mount applications. Endevco signal conditioner models 133, 2771C, 2775B or OASIS 2000 computercontrolled system are recommended for use with this high impedance accelerometer.
