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" .
