Wheatstone Bridge Amplifier "DCBA" Series
Bridge amplifier for small strain gauges
DCBA1ME and DCBA2ME amplify the voltage difference of a full resistance bridge. DCBA1ME supports one bridge, while DCBA2ME supports two bridges. DCBA1MF is almost the same as DCBA1ME but is equipped with a rotary potentiometer for fine adjustment. It is a bridge amplifier that amplifies the inverting and non-inverting output signals of a Wheatstone bridge.
