Sensitiveness:

The sensitiveness might be defined under the two situations:

 (a)       While the governor is considered like a single entity.

 (b)       While the governor is fitted in the prime mover and this is treated as part of prime mover.

 (a)       A governor is called to be sensitive while there is larger displacement of the sleeve because of a fractional change in speed. Smaller the modification in speed of the governor for a specified displacement of the sleeve, the governor shall be more sensitive.

                           . . . (12.27)

 (b)       The smaller the modification in speed from no load to the total load, the more sensitive the governor shall be. According to this definition, the sensitiveness of the governor will be estimated by the ratio of speed range to the mean speed. The lesser the ratio more sensitive the governor shall be

here N₂ - N₁ = Speed range from no load to full load.
