Pendulum with low-friction pointed bearings and electro-magnetic angle sensor for measuring simple harmonic motion of a weighted pendulum with movable weight.
The deflection of the pendulum is detected by a Hall sensor that converts the angle to an electrical signal proportional to the angle so that the oscillation can be recorded using an interface unit, a Y-t plotter or a storage oscilloscope.
Length of pendulum: 1 m
Mass of pendulum: 1 kg
Output voltage: ±5 V
Output resistance: 500 Ω
Power supply: 12 V AC
Diameter of tube: 10 mm
Weight: 1.4 kg approx.
