SG-IP-4P Strain Gauge Amplifiers
Single channel strain gauge amplifier for parallel operating of up to 4 transducers
About the SG-IP-4P Strain Gauge Amplifiers
This single channel strain gauge measuring amplifier SG-IP-4P allows supply and signal evaluation of up to four transducers with normalized sensitivity and 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 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 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.
