Force balancing: Power-balanced fused quartz Bourdon tubes utilize a spiral Bourdon tube to exert drive over a pivoting armature that contains a mirror, the reflection of a beam of sunshine from the mirror senses the angular displacement and current is applied to electromagnets within the armature to stability the power within the tube and convey t
Force-well balanced fused quartz Bourdon tube sensors work on exactly the same basic principle but uses the reflection of the beam of light from a mirror to sense the angular displacement and current is placed on electromagnets to balance the drive on the tube and convey the angular displacement back to zero, The present that's applied to the coils
