Oven Preheat vs. Duct Loss/AHU efficiency
Butelja; Thank you for the response. I suppose heat storage might be a future consideration. As oven operators were asked to record time of day at process start, it was discovered that ventilation and heating were simultaneaous several times daily. Simple ducting and air handling between ovens...- easypilot

Oven Preheat vs. Duct Loss/AHU efficiency
I am trying to improve the efficiency of a painting facility. Five natural gas fired ovens randomly heat 1,000 to 5,000 cubic feet each of 20ºC to 40ºC (midwest US climate) ambient air initially. Upon process completion, 200ºC to 250ºC oven air is ventilated down to <50ºC whereupon oven doors...- easypilot

optical range finder
nbucska -- Thank you for your response. We place a large steel axle on rests built onto the bed of our 200 ton horizontal hydraulic press. I am currently using a 2 wire hall effect sensor affixed to the thimble of an inside micrometer. A long steel rod, precisely cut to our required wheel to...- easypilot

optical range finder
Our production line is destroying hall effect sensors. They are temporarily mounted on an axle to sense a steel wheel position as it is pressed on to the axle. When in range, the two wire switching sensor simply halts the hydraulic press cycle. The close proximity of this sensor to the wheel...- easypilot
