     How does hairspring work?

     A balance spring, or hairspring, is a spring attached to the balance wheel in mechanical movement or else. It causes the balance wheel to oscillate with a resonant frequency when the pressure gauge movement or else instrument is running, which controls the speed at which the wheels of the timepiece turn, thus the rate of movement of the hands.

    What is the use of hairspring in pressure gauge?

    Hairspring in a pressure gauge eliminates the Hysterisis (backlash/angularity) error caused in the quadrant (gear and pinion mechanism) and the weight of the pointer
