When pressure is introduced into the Bourdon tube, what action causes the mechanism to move?
Answer
The flattened cross-section attempts to force the tube into a more circular shape.
Because the tube's cross-section is flattened (slightly oval), the internal pressure attempts to make the cross-section more circular, causing the entire curved tube to try and straighten out.
