A governor is said to be sensitive when it readily responds to a small change in speed. The movement of the sleeve for fractional change of speed is a measure of sensitivity.
Sensitiveness =
Hunting: If a governor is too sensitive i.e. for a small variation of speed causes a large change in the sleeve movement. Thus, a governor is said to be hunting if the speed of the engine fluctuates continuously above and below the mean speed.
Stability: A governor is said to be stable when for each speed within the working range there is only one radius of rotation of the fly-ball at which the governor is in equilibrium.
The stability and sensitivity of a governor are inversely proportional to each other.
