VIBRATION INSTRUMENT Charge Amplifier Model-4001b

This equipment is a micro-charge amplifier that amplifies charge signals virtually ranging from DC to 50 kHz. It is best suited for use in conjunction with a piezoelectric pressure sensor.

Simple, easy-to-use instrument engineered with emphasis on basic performance.

Discharge time constants selectable between LONG and SHORT.

Built-in output calibration signal (supplied from the power supply unit).

Compatible with various types of sensors, such as vibration, pressure, and force, as long as they are of the charge output type.

Ready for concurrent use with the charge amplifier Model-4035.
