SG-IP Strain Gauge Amplifiers
Single Channel Strain Gauge Amplifier
About the SG-IP Strain Gauge Amplifiers
The single-channel strain gauge measuring amplifier SG-IP allows supply and signal evaluation of one transducer with a strain gauge full bridge greater than 300 ohms. Input and output are galvanically isolated. 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 EMC die-cast aluminium enclosure (IP65) which is suited for applications in rough and industrial environments.
The amplification of the amplifier can be adapted by an internal precision resistance.
The potentiometers Z (Zero) and G (Gain) which are accessible after removing the enclosure cover allow a calibration correction. By means of an internal dip switch a change of the range of the potentiometer Z (Zero) can be reached. To allow a zero range shift a basic load / tare can be suppressed by a resistance electrically.
