Model 711A is a miniature IEPE single axial accelerometer with waterproof rating IP68, permitting simultaneous shock and vibration measurements under humid/greasy dirt environment. 711A 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 adapter is available. Polarity inversion protection for the amplify circuit is inherent in the circuit design. The welded titanium construction provides a lightweight hermetic housing. The glass insulated connector provides long-term stability, special waterproof connectivity ensure the seal assembly of sensor and cable exit. The 711A provides wide frequency response, which is ideal for dynamic vibration and shock measurement especially for lightweight structures and drop testing for the packaging industry. 711A integrated with customized length cable and a 10-32 electrical connector.
