SG-2K-IP Strain Gauge Amplifiers
Dual channel strain gauge amplifier
About the SG-2K-IP Strain Gauge Amplifiers
The dual-channel strain gauge measuring amplifier SG-2K-IP allows supply and signal evaluation of two connected transducers 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 application in rough and industrial environments.
The amplification/channel of the amplifier can be adapted by an internal precision resistance.
The potentiometers Zx (Zero) and Gx (Gain) which are accessible after removing the enclosure cover allow a calibration correction for each channel.
By the means of an internal dip switch/channel a change of the range of the potentiometer Zx (zero) can be reached. To allow a zero range shift a basic load / tare can be suppressed by a resistance electrically.
