Model 2262A Piezoresistive accelerometer Features Description • DC response • 1000 g and 2000 g full range • 500 mV full scale output • Hermetically sealed The Endevco® model 2262A accelerometers are rugged, fluid damped transducers of the piezoresistive type. Endevco’s Piezite® type P-11 semiconductor strain gage elements are used in a bridge configuration, providing a low impedance output with 10 Vdc excitation. The output is high enough to drive most tape recorders, data aquisition systems, and low frequency galvanometers directly, without amplification. Viscous damping extends their useful frequency range and reduces the effect of spurious, high frequency vibrations. Typical applications for these accelerometers include transportation environmental testing and transient accelerations on structural members. Endevco model 126, 136 or 436 recommended as signal conditioner and power supply. .625 HEX (15.88) KEYING DOT FOR CONNECTOR ORIENTATION 3 2 5 .17 CENTER OF (4.3) SEISMIC MASS .22 (5.6) 6 4 1 MATES WITH ENDEVCO 3022B CABLE .610 DIA (15.49) DIRECTION OF POSITIVE OUTPUT CENTER OF SEISMIC MASS .140 (3.56) .58 (14.7) .130 MIN THD (3.30) 1.00 (25.4) .280 (7.11) .028 (.71) .006 (.15) .003 (.08) .250 DIA (6.35) .540 DIA (13.72) MODEL 3022B CABLE ASSEMBLY 10-32 UNF-2B THD RECEPTACLE ACCELEROMETER CASE 1 2 3 4 5 6 SCHEMATIC 1 2 3 4 5 6 STANDARD TOLERANCE INCHES (MILLIMETERS) .XX = +/- .03 (.X = +/- .8) .XXX = +/- .010 (.XX = +/- .25) RED + IN GRN + OUT WHT - OUT BLK - IN CABLE SHIELD
