SG-KS-4P Strain Gauge Amplifiers

Single Channel Strain Gauge Amplifier for Parallel Operating of up to 4 Transducers with Normalized Signal

About the SG-KS-4P Strain Gauge Amplifiers

This single channel strain gauge amplifier SG-KS-4P allows supply and signal amplification of up to 4 transducers with normalized signal. The transducer connection, which should have a full bridge resistance greater than 300 Ohms, can be done in 4-wire technology. For further evaluation standard analogue outputs are available. The measuring amplifier is built into a plastic enclosure (IP20) which is intended for top hat rail mounting. The amplification can be adapted by an internal precision resistance. The potentiometers Z (Zero) and G (Gain), which are accessible via the enclosure cover, allow a calibration correction. By means of an internal dip switch, a change of the potentiometer Z (zero) range can be achieved. To allow a zero range shift, a basic load / tare can be suppressed by a resistance electrically.
