SG-KP Strain Gauge Amplifiers
Single Channel Strain Gauge Amplifier for DIN Top Hat Rail Mounting
About the SG-KP Strain Gauge Amplifiers
This single channel strain gauge amplifier SG-KP allows the supply and signal amplification of a strain gauge transducer. The connecting of the transducer 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 in 6-wire-technology. For further evaluation standard analogue outputs are available.
The measuring amplifier is installed into a plastic enclosure (IP20) which is intended for the top hat rail mounting.
The amplification can be adapted by an internal precision resistance.
The potentiometers Z (Zero) and G (Gain), which are accessible above the enclosure cover, allow a correction of the calibration. By means of an internal resistance, a change of the zero-range can be achieved.
