SG-INL Strain Gauge Amplifiers
Single Channel Inline Strain Gauge Amplifier
About the SG-INL Strain Gauge Amplifiers
The single-channel inline strain gauge measuring amplifier SG-INL allows supply and signal evaluation of a transducer with a strain gauge full bridge greater than 300 ohms. The connection is done in 4-wire technology. For further evaluation standard analogue outputs are available. The measuring amplifier is built-in into a robust aluminium enclosure (IP20) which is suited for applications in rough and industrial environments.
The amplification can be adapted by an internal precision resistance.
The potentiometers Z (Zero) and G (Gain) accessible after removing the enclosure cover, allow a correction of the calibration. By means of an internal dip switch a change of the potentiometer Z (zero) range can be achieved.
