@insipidintegrator Proportional control is just the (continuous) difference of the instantaneous value from setpoint. That is noisy because it is always making some adjustment.

The diameter of the shaft is somewhere between 3mm and 6mm. The rotation rate is no more than 100rpm. The pressure outside of the seal is around 10m of water.
