Piezoelectric Accelerometer(Charge type)

Shear type
The Shear type is constructed so that each Piezoelectric element has shear that is proportional to applied acceleration between the poles. It is useful for low frequency vibration measurement even in the environments of large temperature change because of it is hard to be effected by the Pyroelectricity. Furthermore, it is less sensitive to the strain in the base.
Pressure type
The Pressure type has a Piezoelectric element fastened by a screw between a piece of weight and the Base. Measurement of pretty large Sock is possible because of its advanced mechanical strength. The Resonant frequency is high for its sensitivity. Therefore, the accelerometers of this type can be used not only for general applications but also for measurements on the High speed rotational machineries or detection of leakage from the Pipe lines.
Bending type
The Bending type has a construction to get the signal from the Piezoelectric elements glued on a metal plate which is bent being applied an acceleration. This is light in weight and has high acceleration sensitivity to be suitable to monitor earthquakes or small vibration of the testing models of Dam, Power station or small equipments.
Dual-line Output Charge Amplifier
Dual-line output charge amplifier is a charge/voltage converter which converts charge output of accelerometer to voltage with low impedance. It operates being supplied current by measurement equipment with a constant current source.The output signal is obtained superposed on the current supply.
