Re: Rail Track Sensors

[udayhere2002]

what kind of sensors can i use in building a rail track inspecter.
wat is the specification of the sensors.
can i fix  the directionality for any sensor.ex.photo transistor

What do you need inspect for? Search online for a sensor that can find what you need . . . perhaps ultrasonic scanner would work?

yes

i hve to ispect the track & detect the broken tracks & error in distance between the tracks.can u give me an idea.

[Admin]

are these real train tracks?

are the broken parts just small cracks, or seperation in the track?

its hard to tell you what sensor if i dont know the details, could you explain more?

you can probably just use a photoresistor sensor, so when the light
'breaks,' that is where the track is damaged.

its a white chart paper track on black background.so could u plz say me wat kind of sensors with exact product name.

[Admin]

a photoresistor/phototransistor sensor, with an LED illuminator, will work best.

just search your favorite electronic parts distributor for either of those names. they are extremely common and very very cheap.
