Pohl Forced Oscillation Device Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-10458

The forced oscillation device according to Prof. R. W. Pohl is a physics laboratory apparatus used for demonstrating free oscillation, forced oscillation, damping, resonance and phase shift in a torsional pendulum system. It is designed for schools, colleges and university physics laboratories studying mechanical oscillations and vibration behavior.

Product Description

The Forced Oscillation Device according to Prof. R. W. Pohl from Lab Glassware Manufacturer is intended for practical demonstrations of torsional pendulum motion. In a typical experiment, a rotating oscillator is driven periodically, and students observe how amplitude changes with driving frequency and damping.

This apparatus is useful for mechanics, wave-motion and resonance lessons because it makes abstract oscillation theory visible. Exact wheel material, drive motor specification, damping method, frequency range, scale design, power supply, sensor compatibility and supplied accessories should be confirmed before final catalogue publication or tender submission.

How to Use the Forced Oscillation Device according to Prof. R. W. Pohl

1. Place the apparatus on a stable, level laboratory bench.
2. Check the oscillator, torsion element, pointer, drive mechanism and damping unit before use.
3. Connect only the approved power supply and cables specified for the final model.
4. First observe free oscillation by displacing the oscillator and releasing it gently.
5. Apply damping if the apparatus includes an adjustable damping system.
6. Start the periodic drive at a low excitation frequency.
7. Increase the driving frequency gradually and record amplitude at each setting.
8. Identify the frequency at which maximum amplitude occurs and discuss resonance.
9. Observe phase shift between the exciter and oscillator if the apparatus includes suitable pointers or scales.

Safety note: Keep hands, loose clothing and cables away from moving parts. Do not exceed the confirmed motor voltage, damping current or frequency range, and switch off the apparatus before making mechanical adjustments.

Care & Maintenance

• Keep the oscillating wheel, scale and pointer clean and dust-free.
• Check drive belts, springs, connectors and damping parts before every practical session.
• Store cables and power units separately to avoid strain on connectors.
• Do not lubricate bearings, adjust damping magnets or open the drive unit unless the final manual allows it.

Frequently Asked Questions

What is a Pohl forced oscillation device used for?

A Pohl forced oscillation device is used to demonstrate free oscillations, forced oscillations, damping, resonance and phase shift in a torsional pendulum system.

What principle does the Pohl torsional pendulum demonstrate?

It demonstrates how a mechanical oscillator responds to periodic external driving and how damping changes amplitude, resonance behavior and phase relationship.

Is this apparatus suitable for school and college physics labs?

Yes. It is suitable for supervised senior school, college and university physics laboratories studying oscillations, resonance and mechanical vibrations.

Does the apparatus include electromagnetic damping?

Electromagnetic damping is not confirmed. Add eddy-current brake or damping-current details only after checking the final product specification.

What measurements can students take?

Students can measure period, amplitude, damping effect, resonance frequency and phase shift when the final model includes the required scale, drive and timing features.

Does it require a power supply?

Most forced-oscillation versions require a power supply for the drive motor and possibly the damping system, but the exact voltage and supply type must be confirmed.
