Governor
Model No: THMC-02
- A base unit contains a variable-speed motor.
- The Hartnell governor raises the sleeve against a compression spring.
- A sensor measures the position (lift) of each governor sleeve as it rises.
- The motor turns each of three different governors: Proell, Porter and Hartnell.
- Each governor uses rotating weights (masses) and levers to raise a ‘sleeve’.
- The Porter and Proell governors raise the sleeve against the action of gravity.
- Users may also adjust the arm length and rotating mass of the Hartnell governor.
- The clear dome includes an interlock that shuts off power to the motor.
- Additional weights (supplied) allow the user to vary the mass of the sleeve of the Porter and Proell governors.
- This allows students to see the governors and use them in safety while still giving them access to examine or adjust them.
