Bridge completion
The Wheatstone bridge used in most strain gage measurement circuits usually
consists of (a) the gages for actively measuring the strains and (b) precision
resistors for completing the circuit. In the GN410 and GN411 bridge completion
can be for full, half and quarter bridge configurations. Completion resistors can
be internal (incorporated in the GN410 and GN411) or external (when required).
Bridge completion - full (4/4) bridge
A full bridge type sensor is a sensor that has all four bridge resistors on-board,
no completion is required.
