Strain gauge amplifier SGA-2

signalmeasuringdifferential

The SGA-2 strain gauge bridge amplifier is a differential high speed front-end amplifier with high precision. Strain gauges can be connected to the measuring bridge in full bridges, half bridges or ¼ bridge construction. Among its main features of the amplifier include 4-wire and 6-wire technology, two independent channels per module, low output noise, 1.5 MHz bandwidth with amplification x1 and x10, small voltage offset drift and auto-offset compensation. The USB / RS458 software interface can be used to configure all settings and to monitor the output signal. Visually, it impresses with its robust and modular design. By special arrangement and interconnection of the strain gauges at the measuring bridge, different temperature compensations can be achieved. As a result, thermal expansions cancel each other and certain expansion components can be compensated or selected.
