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.

White Paper – Data Security and Know-How Protection
Our data is constantly exposed to the danger of being intercepted or stolen as it wends its way over global data networks. Data security measures and measures for protecting intellectual property should not, however, first be implemented when data is exchanged – companies must lay the foundation for these measures within their own organization.

White Paper – Collaboration in the PLM Context
The influence exerted by the Internet of Things (IoT) means that there is a steadily growing need for collaboration in industry. Partners from new industries and areas of application need to be integrated in cross-company business processes to ensure that the lifecycle of smart, connected products can be managed from end to end.
