DescriptionThe BCM-1 bridge completion module provides a convenient means of completing the Wheatstone Bridge circuit used for strain gage measurement. The module can be used for quarter-bridge measurements with 120 or 350 Ohm gages, or for half-bridges with gages of any resistance. In addition, a bridge balance adjustment potentiometer is provided to zero the bridge output. Screw terminals are provided for strain gage, excitation and output signal connections. Quarter-bridges with two- or three-wire hook-up can be accommodated.
