Thank you for all feedback, overwhelming. I should have given more information at the beginning. We cannot use proximity sensor, as the guide pipe is plastic and partial steel. The pipe end is close to the flare and can reach 800 centigrade. To hot for any instrument installation. We have tried...
The ignition pellet can be launched during day or night. The pipe length can be up to 2000 meter and continuously purged with dry air. The internal surface is clean but the wall may be sooty by burned hydrocarbon. Travelling speed will be in the range of 10 to 100 m/s. Using a ball bearing on...
This is a small pellet that is supposed to ignite when leaving a pipe, which can be made of steel and/or GRP (plastic). As long as the pellet is within the pipe nothing should happened. Moving force is compressed air. Sensing a steel pipe is fairly easy but both steel and plastic on the same run...
We need suggestions on how to detect the outlet of a 1-inch pipe. A unit will travel in the pipe and detect the wall and we need to detect the pipe end in less than 4 millisecond. The sensor must be electronic and we are thinking of an IR-sensor. The sensor must be insensitive to daylight. Do...
