PCB® charge output accelerometers utilize piezoceramic sensing elements, in shear mode configurations, to directly output an electrostatic charge
signal that is proportional to applied acceleration. These sensors do not contain built-in signal conditioning electronics. As a result, external signal
conditioning is required to interface their generated measurement signals to readout or recording instruments. The sensors’ charge output signals
can be conditioned with either a laboratory-style, adjustable charge amplifier or an in-line fixed charge converter.
