Types 8202A... and 8203A... are high impedance, charge mode accelerometers designed for vibration measurements where temperature extremes may be experienced. A Ceramic Shear sensing element produces a significant charge output that can be easily converted into a useable analog voltage signal via a charge amplifier. Kistler’s shear technology assures high immunity to base strain, thermal transients and transverse accelerations. A unique connector design features a ceramic insulator for long-term stability even at extended operating temperatures. Additional features include high frequency response, lightweight and hermetic sealing. It is recommended that low noise transducer cables be used between the accelerometer and the input of the charge amplifier or charge converter.
Internal of these hermetically sealed accelerometers is a shear mode, ceramic sensing element, providing a significant charge output. Type 5050A... In-Line Charge Amplifier is recommended for use with Types 8202A... and 8203A... . Type 5050A... is a lower cost alternative to the laboratory amplifier allowing the measurement system to take on the appearance of the traditional voltage mode accelerometer and power supply/coupler.
