Intelligent sensors cut risk factor… let the censor have the last word

CTM censor is a stand alone unit originally designed for positioning at the end of a potato grading line. Its intelligent sensors a programmed to recognise and remove foreign objects that have passed previous checks.

Aimed primarily at growers supplying potatoes to processing factories or packhouses, it offers peace of mind by cutting the risk of foreign objects such as stones, glass or metal being shipped with the produce.

A short in-feed belt spreads the crop over six channels which are fitted with sensors which are actually ‘intelligent bars’ each with its own microprocessor which uses ‘real time signal analysis’ to measure the varying density of the material passing over it. A foreign body such as a plastic cap, wood or any of the above items hitting one of the bars will cause it trigger a signal. This opens a compressed air valve and raises a flap, blocking the suspect object which drops to a reject conveyor before the flap quickly returns to its closed position. In the meantime potatoes cascade across the sensors at an adjustable rate of 20 to 50 tonnes per hour.

When foreign objects result in downtime, processors’ penalties are being passed on to suppliers. Let the censor have the last word on your line…it could save you financial and commercial loss.
