WS-2401 Two-channels Charge Conditioning Amplifier

1. Overview


Charge amplifier type WS-2401 is a four functions amplifier consisting of charge amplifier, voltage amplifier, low-pass filter and integrator. It is a comprehensively equipped charge conditioning amplifier. It can be powered from external batt eries DC or AC power supply, making it useful both experiment in the field test and in the laboratory.
2. Main Features
  • Anti-alias low-pass filter
• Small size, light weight, stable and reliable
• 3 digit conditioning to transducer sensitivity
• Switchable for charge and voltage input mode
• Piezoelectric transducers, velocity and displacement ensors can be connect to the amplifier
• Built-in integrators for velocity and displacement
• Power supply is AC or DC
