Ultra-miniature accelerometers, ceramic shear, very low weight / 8778A

Family Type 8778A 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 units are designed for wax or adhesive mounting and are supplied with a custom wrench to facilitate removal after testing.
