Dynamic Strain Amplifiers

Features

AC Strain Amplifiers Models 5683 / 5684

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 5693).

DC Strain Amplifier Model 5693

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 500kHz.
An auto balance function is mounted on the balance circuit, which enables to perform initial balancing operations instantaneously with high accuracy.
