I'm looking to use the LDC1000 to sense the presence of feed (corn based) inside of an auger. The feed could be pellets or finely ground up like flour and anything in-between. The LDC1000 sensor coil will be attached to the bottom of the auger. Directly touching the coil will be the outside wall of the auger which is PVC plastic (0.250" thickness). Inside of the auger is metal flighting.... essentially a long spring rotating which moves the feed forward. I am assuming I will see the flighting (spring) come in and out of range with the LDC when the motor is running and the flighting is turning. My question is, will I be able to detect the presence of feed inside of the auger? Often times a feed auger is running but no product is flowing due to having an empty bin (source of feed) or other issue. In the case the auger is empty there could be 0-0.5" of feed sitting on the bottom of the auger that the flighting can't reach and leaves behind. When the auger is full of feed there will be 1.5-3" of feed inside of the auger. Can the LDC1000 be used to differentiate between 1/2" of feed and 1.5" of feed after blasting through 1/4" of PVC plastic? Any tips or suggestions? I have the dev kit coming in the mail and a auger test fixture ready to go.
