The Kistler 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
