MODEL-4001B
CHARGE AMPLIFIER

  • 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.
