The described single-channel strain gauge measuring amplifier allows the supply and signal evaluation of up to four transducer with normalized sensitivity and a strain gauge full bridge greater 300 ohms. The input and the output are galvanically isolated. The connection occurs in 4-wire technology. For further evaluation are standard analogue outputs available. The measuring amplifier is built-in in a robust EMC diecast aluminum enclosure (IP65), which is suited for the application in rough and industrial surroundings.

The amplification can be adapted by an internal precision resistance. The potentiometer Z (Zero) and G (Gain), which are accessible after removing the enclosure lid, allow a correction of the calibration. With the help of an internal dip switch, a change of the range of the potentiometer Z (zero) can be reached.

To allow a possible movement of the zero range, a possible basic load / tare can be suppressed with a resistance electrically.
