Columbia Research Labs, Inc. General Purpose Piezoelectric Accelerometer 383

383 High Shock to 20,000 g Sensitivity 0.5 pC/g High Resonant Frequency Low Base Strain Sensitivity Electrically Isolated The Model 383 Piezoelectric Accelerometer is specially designed to accurately measure high amplitude shock and vibration phenomena. The high resonant frequency of 80 kHz results in minimum output distortion due to ringing when measuring impact transients with durations as low as 50 microseconds. The Model 383 incorporates an advanced seismic system in which the sensing crystal is almost totally constrained and free from zero shift following high energy impacts. This accelerometer is not affected by transverse components of impact and is capable of measurements up to its rated value of 20,000 g's and even to 50,000 g's with stable operation. Its rugged construction ensures long life and high performance stability and repeatability. Internal electrical isolation minimizes ground loop problems from noise currents. Consult the factory for customized versions of these sensors. Notes: At +75 Deg. F, 10 g Peak, 100 Hz; Lower Frequency Limit is Determined by Associated Electronics Referenced to Sensitivity @ 100 Hz. Unit is Epoxy Sealed
