Types 8778A500... and 8778A500M14 are high frequency, ultra miniature, lightweight accelerometers that contain a uniquely designed ceramic shear-sensing element. The shear mode element design provides an immunity to thermal transients, base strain and transverse motion.
An internal microelectronic Piezotron ® signal conditioning circuit converts the charge developed in the ceramic element, as a result of the accelerometer being subjected to a vibration, into a useable high level voltage output signal at a low impedance level. The standard Type 8778A500... accelerometer includes a 0.9 m [3 ft] long integral fluorpolymer jacketed cable terminated with a 10-32 neg. connector, while the M14 version features a field replaceable twisted wire pair and connector. The units are designed for wax or adhesive mounting and are supplied with a custom wrench to facilitate removal after testing. Power to the Type 8778A500... accelerometers can be provided by any Kistler Coupler Type 51..., or by any industry standard voltage mode IEPE (Integral Electronic Piezo-Electric) power supply/coupler.
