SG-2K-KS Strain Gauge Amplifiers

About the SG-2K-KS Strain Gauge Amplifiers

The dual-channel SG-Amplifier allows supply and signal evaluation of two transducers with a strain gauge full bridge greater than 300 ohms. The connecting of the transducers, which should have a full bridge resistance greater than 300 ohms, can be done in 4-wire-technology or, by using a long connecting cable or variable length of the connecting cable, in 6-wire-technology. For further evaluation standard analogue outputs are available. The measuring amplifier is installed in a plastic enclosure (IP20) which is intended for the top hat rail mounting. The amplification per channel can be adapted by an internal precision resistance.

The potentiometers Zx (Zero) and Gx (Gain), which are accessible via the enclosure cover, allow a calibration correction for each channel.
