The quartz shear triaxial accelerometers Type 8792A... are rugged, low impedance voltage mode sensors. They are available in four ranges from 25 ... 500 g with sensitivities from 10 ... 200 mV/g. This triaxial design allows simultaneous shock 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 ® microelectronic circuits convert the charge signal from each quartz element into a usable high level voltage signal at a low impedance output allowing the use of low cost cables. An advantage of the low impedance output is the ability to drive long cable lengths with low-noise susceptibility.
The welded, stainless steel construction is hermetically seals the accelerometer when subjected to adverse environments and the ground isolated base design eliminates ground loops.
