SG-AP Strain Gauge Amplifiers
Single Channel Strain Gauge Amplifier with Aluminium Enclosure
About the SG-AP Strain Gauge Amplifiers
The single channel strain gauge measuring amplifier SG-AP allows the supply and signal evaluation of a transducer with a strain gauge full bridge greater than 300 ohms. Input and output are galvanically isolated. The connection is done in 4-wire technology via a pluggable screw clamp terminal block. For further evaluation standard analogue outputs are available. The measuring amplifier is available in 3 versions with different sensitivity. By means of potentiometer for zero and amplification, a calibration correction can be carried out.
