Piezoelectric accelerometer 8203A50

shearG-forceultra-light

Short description
Type 8203A is a high-impedance, charge-mode piezoelectric accelerometer designed for vibration measurement in environments that may experience elevated temperatures. A ceramic shear sensing element provides significant charge output suitable for conversion to an analog voltage via a charge amplifier. Kistler shear technology delivers high immunity to base strain, thermal transients and transverse accelerations. The connector uses a ceramic insulator to maintain stability at extended operating temperatures. Additional characteristics include high frequency response, lightweight construction and hermetic sealing.
