Model 517A is an IEPE single axial accelerometer permitting simultaneous shock and vibration measurements. 517A features an annular shear ceramic crystal which exhibits excellent output stability over time. The accelerometer incorporates an internal circuit in a twowire IEPE system which transmits its low impedance voltage output through the same cable that supplies the constant current power. Signal ground is connected to the outer case of the unit. Isolated mounting studs or housing are available. Polarity inversion protection for the amplify circuit is inherent in the circuit design. The welded stainlesssteel construction provides a lightweight hermetic housing. The miniature 10-32 glass insulated connector provides long-term stability over the operating temperature range. In addition to adhesive mounting, the 517A has M5 threaded screw for mounting on the test object. The 517A provides wide frequency response, which is ideal for shock measurement especially for lightweight structures and drop testing for the packaging industry. Senther’s model 11-3 is a 10-32 to BNC breakout cable for the sensor.
