🧭 Bourdon Tube Pressure Gauge: Pointer Response, Linkage Error and Pulsation (2D)

Front view of a Bourdon tube pressure gauge with its dial and the flattened C-tube that opens as the pressure rises. Change the dial range, the mean pressure, a pump pulsation, the pointer damping and natural frequency, a snubber and the linkage error, and watch the reading follow, overshoot or ring. Overshoot, calibration error, deep-sea hydrostatic pressure and the pulsation transfer function are checked numerically, with four in-page numerical checks.
