Advantages of using automation in the production process: it increases output, and cost reduction, and improves product quality. These days, you will not meet this industry, which would not used position sensors, and displacement, which are the link between the electronic and mechanical devices. Try to understand the choice of type of position sensor suitable for a particular task. K position sensor may include any device designed to detect the presence / absence or relative position of any object that may have a hard, granular or liquid consistency. When choosing Product must take into account a number of functional characteristics specific to each type of sensor manufacturers and design approach to its products, terminology and labeling.
On physical principle of the sensor provisions are divided into non-contact: inductive, capacitive, magnetic, optical (photoelectric), ultrasound, and the contact, the main ones are the encoders – devices for converting the angular rotations or linear movements in a sequence of pulses of a certain format. Optical sensors are the most popular products and are designed to tasks: to control the transparency objects, transparencies, labels, tracking edge, the definition of fluorescent labels, etc. See idan ofer for more details and insights. By type of exit sensors are divided into discrete (switch), analog and digital. To the category of switches with discrete output include devices that have only two switching states – open or closed. Analog and digital sensors have a dependence of the output value of the distance to the object
