Smart Gate Pulley System

PS-3702   - 

Smart Gate and Super Pulley together in one kit. Super Pulley attaches directly to the Smart Gate, providing a simple, low friction system to measure position, velocity and acceleration or investigate rotational motion.

Overview

The most advanced photogate available. The Smart Gate is four photogates in one!

The Smart Gate has dual Photogate beams spaced at 1.5 cm to accurately measure speed. Built-in laser switch (when used with any laser) allows you to time objects too large to fit through the standard Photogate. Other features include a slot for Photogate Tape, and an auxiliary port for an additional Photogate or for the Time of Flight Accessory.

The Smart Gate System needs only one interface connection. The Photogate daisy-chains to the Smart Gate. The Smart Gate is not compatible with the GLX or the SPARK Science Learning System.

The Smart Gate Pulley System's Super Pulley attaches directly to the Smart Gate, providing a simple, low-friction system to measure position, velocity and acceleration. Additionally, with the pulley removed, the smart gate can be used to perform standard photogate experiments.

Typical Applications

  • Launch velocity for a projectile
  • Photogate timing for dynamics carts
  • Rotational measurements (in conjunction with a Super Pulley)
  • Pendulum timing applications
  • Acceleration of gravity with picket fence

How it Works:

Photogates are a timing device that measure times of the changes in state of an infrared beam that is blocked by a flag of known length, as well as the times the beam is unblocked. Using the flag length, and the blocked time, students can calculate speed. The smaller the flag length, the more 'instantaneous' the measurement becomes. Using a "Picket Fence" (a card with multiple flags), students can calculate acceleration. Photogates can also measure the rotation of our Smart Pulley which features wide enough spokes that act as 'flags' to block the photogate's infrared beam. With a pair of photogate beams velocity can be calculated using the distance between the beams and the time between when the two beams are blocked. The Smart Gate allows you to do this with a single photogate because it includes two photogate beams spaced exactly 1.5 cm apart. And if you want to space the two photogates further away, an additional Photogate Head can be connected to the Smart Gate's auxilliary port and placed at a known distance.

The Smart Gate is an incredibly versatile photogate timer.

In this video we walk you through setting up this photogate system and using the dual photogate beams to investigate the motion of carts, pendulums, projectiles, and carts.

Additional features not shown in this introductory video include connecting a second photogate in the auxiliary port, the laser switch, and the slot for photogate tape. See the product manual for full details.
