ClearView Seed uses Conveyor Components switches to monitor our 2 primary legs that load and unload our facility. For 30 years they have performed without any interference from us or maintenance crews. We operate in a high plains environment from 100 degrees to 30 below zero and rely on the systems to warn us if leg speed starts to drop. Early warning and intervention is key to preventing equipment and inventory damage, never mind the labor cost to clean up a plugged leg. We are now updating our switches to the newer style MSD-1 and expect to get another 30 years of trouble free service.
