An “Electronic Eye”.

An electronic eye is a device that can do hundreds of different things. In electronics and engineering it is called a phototube or a photocell. Photocells are widely used at metallurgical plants, in machine plants, in chemical and food industry. In machine plants an “electronic eye” can be used for inspecting machine parts. If the parts are worked not well enough, they do not reflect enough light into the phototube and are sorted out by a device as bad ones.

An “electronic eye” does another important work at a metallurgical plant. In the making of steel it is necessary that the temperature of molten metal be exactly right. As the steel gets hotter and hotter its colour changes from red – hot to orange and at last to white. By fixing the exact colour of the metal, a phototube, gives the most accurate measurements of its temperature. By passing the electric current of the definite strength to the controlling device, the phototube can

bring the metal to exact temperature wanted.

Photocells can be also used at canning factories where they can count the fimshed cans of food.

A phototube is placed on one side of the belt and a lamp producing a light beam is put on the other.

Every time a can comes between the light and the “eye” the current is stopped. Each time the electric impulse is started, it moves the counter one digit. The process results in me accurate count of every can moving along the conveyor of finished production.
