The switches that I've tried have been looking down through the linkage and yes, I'm picking up on the chain pins or rolls. The problem with fiber optics is once the face is oily it stops working, the inductive worked semi well but the chain has a 1/2" side to side movement that ended up causing...
I'm looking for something similar to that. The chain pitch is 6" on one chain and only 3" on the other - it may be too tight of an area for a sprocket. A flipper arm of some sort may work - has anyone used something similar to this to actuate a prox switch?
The only problem with the drive is that it's around 50' away from where the chain must be read - this is on a lubrication system that can't be relocated. There is too much chain stretch in 50' to maintain shot-to-point lubrication.
I have a chain in an oven that does not exit the oven that I need to sense the chain links. The oven is 400+F degrees. The atmosphere in the oven is smokey with formeldehyde and oil. I've tried a high temperature inductive switch and fiber optics but neither worked well. Has anyone created a...

I have a project in which I need to design a gear drive or similar drive system (perhaps belt drive) to turn two seperate shafts which hold a number of wire brushes (diameters and quantities vary, typically the brushes are 12" dia and there could be 10+ of them on a shaft). The shafts sit...

I'm trying to find the most economical, inexpensive pump to dispense a dry film lubricant (mineral spirit based), lighter than water. Dispense amounts can vary from large to small. I was thinking along the lines of a windshield washer pump, anyone else have any ideas? THANKS!!
