Type 8278A... is a wide frequency, ultra miniature, light weight accelerometer that contains a uniquely designed ceramic shear sensing element. The shear mode element design provides an immunity to base strain and transverse motion.
The standard Type 8278A... accelerometer includes an integral repairable Teflon jacketed 3ft. long cable terminated with a 1032 pos. connector. Special length cables are also available. A 1729 10-32 neg. to 10-32 neg. adapter is provided to facilitate connection to standard extension cables with 10-32 pos. connectors. Type 8278A... is designed for wax or adhesive mounting and is supplied with a custom wrench to facilitate removal after testing.
External signal conditioning converts the charge developed in the ceramic element, due to shock and vibration, into a low impedance voltage signal. For example, the Type 5050A... In-Line Charge Amplifier, can be powered by a power supply/coupler like Type 5165A... to create a representative voltage signal.
