Ultrasonic interference pattern recognition products

Hi,
I'm looking for manufacturers of systems for automatic recognition/control of objects. What we want to do is to check whether a screw is fully down or not. (Measurement of the distance between the top of the screw and the surface which it is screwed against, preferably with some kind of interference pattern recognition.)

Thanks in advance,

Martin Nyman

Re: Ultrasonic interference pattern recognition products Without knowing everything about your application, I may be missing some important reason to use UT. However, for accurate and practical distance measurements, we have used these sensors:

and I am sure there are other vendors of similar products.

Re: Ultrasonic interference pattern recognition products Thank you for your quick reply,

The reason for using ultrasonic equipment would mainly be the price, I don't know the exact cost of the systems you mentioned but the ones I have seen are fairly expensive (1000$ and upwards). We need a cheaper solution. Also, we only need a resolution of 0.3mm or better.
