[?]: Sensors for measure distance between moving head

Post by pi14 » Tue Mar 01, 2011 1:35 pm

Hello.

I am looking for distance sensors with analog output.
Sensors will be used for measure distance between moving head (where the sensors are mounted) and tooth on big sprocket.
There will be two sensors for measuring two distances (front and side of the tooth).

For better idea i attached the picture of this sensors.

I dont know what kind of sensor are that (foto, inductive, ultrasonic, ...).
If you have ever saw that kind of sensor please help.

Thank you.

Hello,

You're picture is not very clear.
It seems the bracket is in between the sprocket.

I know that the most resistent sensor against dirt is a inductive one.
Some sensors have an analogue output range.
