Photoelectric Displacement Sensor Manufacturer

Photoelectric Displacement Sensor Manufacturer

Photoelectric Displacement Sensor Manufacturer

(OP)
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.
 

RE: Photoelectric Displacement Sensor Manufacturer

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.
