Features

    AC Strain Amplifiers Models 5783

  • Excellent in high sensitivity, high stability and in noise-resistant capability ensuring for measurement in the use of strain gages.
  • Model 5683 uses the frequency of 5kHz in its bridge power supply, which ensures the response characteristics from DC to 2kHz.
  • Model 5684 uses the frequency of 2kHz in its bridge power supply, which ensures the response characteristics from DC to 10kHz.
  • An automatic volume elimination function is installed on the balance circuit.
  • A bridge circuit disconnection checking function is equipped on the system, which enables an easy trouble-free operation during measurement (common to Model 5793).
  •  

    DC Strain Amplifier Model 5793

  • Suitable for a high accuracy measurement with the use of strain gage type transducers (for measurement of load, pressure, torque, acceleration and so on).
  • A stabilized voltage of 2, 3, 5, 9 or 10 V is used in its bridge power supply, which realzes a hircuit higher respons frequency of DC to 100kHz.
  • An auto balance function is mounted on the balance circuit, which enables to perform initial balancing operations instantaneously with high accuracy.
