The model 517P is a light weight piezoelectric accelerometer designed specifically for high amplitude shock measurement. The unit is hermetically sealed and ideal for use in extreme environments. This sensor is the industry standard for impact/shock accelerometers. The model 517P features a M5 threaded mounting screw for high-g shock. The accelerometer is a self-generating device that requires no external power source for operation. Model 517P operating in annular shear mode. These specially designed crystals exhibit low base strain sensitivity, high resonance frequency, and excellent output stability over time. Signal ground is connected to the outer case of the unit. The accelerometer features a 10-32 connector and requires a low-noise coaxial cable for error-free operation. Senther’s model 11P-3 is a 10-32 to BNC breakout low noise cable for the sensor.
