Timer with Two Photogates Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12546
Jlab Export is a leading Timer with Two Photogates Manufacturer,and suppliers in India
Timer with Two Photogates (code EL-PL-12546) is an electronic timer supplied with two infrared photogates on cords and an AC adaptor, for timing objects as they pass through the light beams. It works in internal and external modes and resolves time to 0.1 ms, fine enough for speed and acceleration measurements on tracks and in free fall. JLab makes the timer and its gates in Ambala, India.

Timing With One Gate or Two
Each photogate sends an infrared beam across its opening, and an object that interrupts the beam signals the timer. With one gate, the time a flag of known length blocks the beam gives its speed: length divided by time. With two gates, the interval between the first and second interruptions gives the average velocity over the gap, and two speeds taken a known time apart give the acceleration. A rise time of no more than 60 ns and spatial resolution under 1 mm fix the moment of interruption sharply.
Mounting the Gates
The threaded stand rod fixes a gate to a retort stand for free-fall or pendulum work, and the bolt attaches it to a roller track. An indicator light shows that the gate is in operation, and leads with 8-pin mini DIN plugs connect the gates to the timer.
