Pulse Counter (Need Help!)

BrunoIST said:

Hello,

im a mechanical enginneer and want to buy or build in case theres nothing cheap avaiable something able to do this:

a pulse counter, something that receives pulses of about 0.5V and count them and when it gets to N pulses it triggers a pulse that will be aquired by another device. Basically its some sort of circuit that counts pulses emitted by a "Incremental Encoder" and when it gets to N pulses it will send a pulse to be aquired by a device that will trigger a laser. Propably i have to do something in PIC but since im a mechanical eng. i dont know much about this. Can anyone help me?

thanks for reading

Thanks for the time,

to amplify the signal wouldnt be a problem though i do wanna the fastest response possible.

I need something that can count to at least a 1000 pulses with a resolution in the order of miliseconds at least, and that when it get to the N pulse (say 1000) it would restart, and start over.


This is to be implemented in a turbine the objective is to this counter receive the pulses from the "incremental encoders" that marks the angular position of the turbine so that the counter triggers a pulse when the turbine blades are on a particular position. This is one time per rotation.

Hope my english can be read.

And im really thankfull for your time
