Half-Bridge Type II Rejecting Axial and Measuring Bending Strain
A half-bridge type II configuration has the following characteristics:
•
Two active strain-gauge elements. One is mounted in the direction of
bending strain on one side of the strain specimen (top), the other is
mounted in the direction of bending strain on the opposite side
(bottom).
•
Completion resistors provide half-bridge completion.
•
Sensitive to bending strain.
•
Rejects axial strain.
•
Compensates for temperature.
