This benchtop unit is used to demonstrate the principle of operation of various centrifugal force governors. The drive with an electronically regulated motor is fitted in the housing. The speed is continuously adjusted using a 10-turn potentiometer and displayed digitally. The governor is placed in a chuck on the drive. The centrifugal masses and sleeve forces can be varied using the accessories included. The stroke can be measured using the marks on the governor shaft. When in operation, a transparent protective lid covers the rotating centrifugal governor. The unit can only be placed in operation if the lid is correctly fitted. The unit is simply placed on a table in the laboratory for operation. It only requires a supply of power.
