Key Features
- Variable-speed motor in the base unit drives each of the three governors
- Porter and Proell governors lift the sleeve against gravity; the Hartnell governor lifts it against a compression spring
- Hartnell governor arm length and rotating mass are adjustable
- Sensor measures sleeve position (lift)
- Motor control with direction, coarse and fine speed adjustment and press-to-stop
- Clear dome with an interlock that cuts power to the motor

About This Product
Each governor uses rotating masses and levers to raise a sleeve as speed increases. Students record sleeve lift against speed for the gravity-loaded Porter and Proell designs and the spring-loaded Hartnell design, then change the Hartnell arm length and mass to see how the characteristic shifts.
