Belt edge detection in 100 degree C hazardous location
I am in need of some type of technology that would detect a belt edge for tracking of the belt. This belt runs in a steam filled oven with an average temperature of 100 deg. Celcius.
I need some type of sensor or system to look through the steam and detect belt edge. Then that signal needs to be sent to some type of controller on the outside of the oven to activate the belt tracking system and send a signal back to our PLC for position monitoring.
