The model CT tilt level controller manufactured by Conveyor Components Company has been redesigned to allow direct placement of the controller in explosive environments. Previously, the electronic control panel had to be placed in a safe area, and only the probe could be placed in the dangerous environment. The new rugged cast aluminum enclosure is designed for NEMA 7 vapor explosion proof and NEMA 9 dust ignition proof environments, with an intrinsically safe output to the tilt probe. Optional epoxy coating is also available for corrosive environments. The unit has external red and green LED indicator lights to indicate the status of the tilt probe. The newly redesigned CT controllers (model CT-105, CT-106 & CT-107) will operate with all previous tilt probes manufactured by Conveyor Components Company. The controller is UL listed, and also has ULc approval.
