摘要:
A comparatively rugged optical lever system has been designed which magnified the movement of concavo‐convex Bourdon gauges by a factor of 545. The system has a reproducible null point that is independent of temperature, but varies linearly, although only slightly, with pressure. The sensitivity graph is linear, and direct pressure measurements can be made to the nearest 0.005 mm of mercury.
