Vibration standard for 1/4-28 mounted accelerometers, measuring range 1000 g / 8076K

The Type 8076K accelerometer is Kistler’s most accurate and repeatable laboratory vibration calibration transfer standard. It features low base strain and mass loading sensitivities, a rugged stainless steel housing, ground isolation and an integral mounting stud. A beryllium mounting base, lapped optically flat, provides optimum coupling between the 8076K and the test unit. Contained within the housing is a piezoelectric assembly consisting of a seismic mass, preloaded to a quartz element stack. The force acting on the quartz measuring element is proportional to the acceleration in accordance with Newton’s Law: F=ma. This element in turn, gives an electrical charge signal proportional to the force and, therefore, to the acceleration. The charge signal is conducted through a low noise coaxial cable, such as the 1631 series, then converted and amplified to a proportional output voltage in a charge amplifier
