Short-Term Timer with 2 Light Barriers Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-10517

The short-term timer with 2 light barriers is a physics laboratory timing system used for measuring short time intervals in motion, free-fall, speed, acceleration, and collision experiments. It is suitable for schools, colleges, STEM laboratories, and physics practical rooms that need more repeatable timing than manual stopwatches.

Product Description

The Short-Term Timer with 2 Light Barriers from Lab Glassware Manufacturer is designed for practical mechanics experiments where an object interrupts one or two light beams. The timer records the event timing, helping students calculate time of travel, average speed, acceleration, period, or interval between two positions.

This apparatus is especially useful with trolleys, inclined planes, free-fall setups, pendulums, rolling balls, and dynamics tracks. Final timing resolution, display range, operating modes, sensor cable length, input voltage, connector type, and mounting accessories must be confirmed before publication or tender submission.

Key Features

• Timing system supplied with two light barriers for motion experiments.
• Useful for measuring short intervals, gate times, transit times, and event sequences.
• Supports speed, acceleration, free-fall, pendulum, and dynamics-track practicals.
• Helps reduce human reaction-time error compared with manual stopwatch timing.
• Suitable for school physics labs, STEM labs, and college mechanics experiments.
• Can be paired with compatible trolleys, ramps, carts, flags, and free-fall accessories.
• Timing resolution, modes, connectors, and mounting system must be confirmed.

How to Use the Short-Term Timer with 2 Light Barriers

1. Place the timer on a dry, stable laboratory bench.
2. Connect both light barriers to the timer using the correct input sockets.
3. Mount the light barriers at the required positions on a track, stand, or frame.
4. Align each beam so the moving object or flag interrupts it cleanly.
5. Select the required timing mode according to the experiment.
6. Reset the timer before releasing the trolley, ball, pendulum, or falling object.
7. Record the displayed time and repeat the trial for reliable results.
8. Use measured distance, flag length, or gate spacing to calculate speed or acceleration.

Safety note: Secure all stands, clamps, and cables before release. Keep hands clear of moving carts, falling objects, and track ends during timing experiments.

Care & Maintenance

• Keep the timer, sensors, and connectors dry and dust-free.
• Do not pull light-barrier cables by the wire; disconnect from the plug body.
• Store light barriers in protective packing to prevent sensor misalignment.
• Check beam alignment and cable condition before every practical session.

Frequently Asked Questions

What is a short-term timer with 2 light barriers used for?

It is used to measure short time intervals in physics experiments involving motion, speed, acceleration, free fall, pendulum motion, and dynamics tracks.

How do light barriers measure time?

A light barrier detects when an object blocks its beam. The timer records the blocking time or the interval between two beam interruptions.

Is it better than a manual stopwatch?

Yes, for many motion experiments. A light-barrier timer reduces reaction-time error and gives more repeatable readings than manual stopwatch timing.

Can two light barriers measure acceleration?

Yes. If the distance between the barriers and the object timing data are known, students can calculate speed changes and acceleration.

Does the kit include mounting stands?

Mounting stands or clamps are not confirmed. Add them only if the final supplied kit includes rods, brackets, holders, or clamps.

What should be confirmed before ordering?

Confirm timing resolution, timing range, display type, sensor type, cable length, connector type, operating modes, power supply, mounting accessories, and warranty terms.
