The Type 8784A5 (top connector) and 8786A5 (side connector) are low impedance, voltage mode accelerometers designed for vibration measurements in single to multichannel applications. The ceramic sensing element components have been designed to provide the level of performance most often required in general purpose vibration measurements. Kistler’s shear technology assures high immunity to base strain, thermal transients and transverse accelerations. Other outstanding features include high frequency response, light weight and hermetic sealing. The unique connector design is rugged and maintains excellent integrity with repeated connections.
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. This output allows for the use of inexpensive coaxial cable, while providing high noise immunity and insensitivity to cable motion. Power to the accelerometers Type 8784A5 and 8786A5 can be provided by any Kistler Type 5100 series coupler or by any industry standard voltage mode IEPE (Integral Electronic Piezo-Electric) power supply/coupler.
