Oven chain switch
Oven chain switch
(OP)
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 flipper arm or other mechanical device so that a typical inductive or photo proximity switch can be used outside the oven environment - the arm or flipper would actuate when ever a chain link passed it?

You can attach stuff to the sprocket wheel or there may already be sensors that sense the sprocket wheel rotation.

Is the motor which drives the sprocket also imbedded in the floor of the oven? If not, any number of sensor types could be used.

Your little device to ride on the links sounds feasible but it is mechanical.
