Hi all,

I am seeking an inexpensive photoelectric displacement sensor. The requirements of the sensor are that it senses over a 10mm range (preferably 0-10mm, but could be greater like 30-40mm), and is accurate to .1mm.

The application is to detect the distance of a rubber tube that will expand and contract due to a pulsatile pressure load. Please let me know if you need any more info.

I will gladly accept correction of my opinion by my colleagues here, but...

I think what you are seeking is expensive. "Photoelectric Sensors" are cheap. "Displacement sensors" are expensive. Typically displacement sensors use lasers in a retroreflective configuration. The bounced laser beam is sensed on a chip of some sort. A corresponding analog voltage calibrated to a distance is output. Never mind the user interface, documentation, & controller that goes into all of that. It all costs a lot of money.

BTW, Keyence, OMRON, Sunx, SICK, several others all make those things. I use an older Keyence LK-G80 laser displacement sensor. 80mm offset, 20(?) mm range, crazy precise tolerance, wonderful device. I didn't buy it, but I think it was in the $3K - $4K range. I thought that I read where they released a less expensive version.
