Kistler Model 8791A250 K-Shear® Miniature Triaxial Accelerometer
The 8791A250 shear triaxial is a low impedance, voltage
mode accelerometer in a miniature, cube-shaped enclosure and designed for adhesive mounting. The triaxial design permits simultaneous impact and vibration measurements
in three mutually perpendicular axes: X, Y and Z.
Kistler's K-Shear design provides a wide operating frequency range
along with extremely low sensitivity to thermal transients, base strain and transverse acceleration. Quartz sensing crystals ensure
the long-term stability not achievable with other sensing materials. Three Piezotron® electronic impedance converters
provide a low impedance voltage output allowing the use of low-cost cables and eliminate the need for charge amplifiers.
Another advantage of a low impedance output is the ability to drive long cable lengths with low-noise susceptibility. The
unit is housed in a titanium case and epoxy sealed to IP67 protection.
• Low impedance voltage output
• Quartz shear sensing elements
• High immunity to thermal transients
• Ultra-low base strain sensitivity
• Miniature cube design
• Light weight
• Conforming to CE
