Sensors are widely used in various applications such as: Color Mark and Registration Detection, Clear or Reflective Object Detection, Counting, Detection, Quality Inspection, Labelling, Level Monitoring, Loop Control, Measurement, Metal Stamping, Temperature Monitoring, Web Monitoring, Wireless.
To verify, from a distance, that bolt threads have been cut into holes in a manifold
To detect extremely small parts as they fall through a web of sensing beams
To provide proximity information to an assembly robot control
To detect of a printed mark on a continuous web of clear or translucent material for accurate control of downstream cutoff
Temperature regulation is an important aspect of many processes within the factory--especially in food manufacturing facilities. In this case, it's imperative for the waffle iron to be hot before the batter is poured into it or the result will be an inconsistently prepared product.
Determining whether or not a bottle has a cap requires additional sensing controls when the production line runs products with various colored caps than when sensing like-colored caps. The sensing solution must be able to detect many colors at a specified distance, while ignoring the product inside the bottle.
Reflective surfaces are one of the more challenging types of objects to sense with a traditional photoelectric sensor. Cylindrical reflective objects are especially difficult to sense due to the light reflecting differently on the various parts of the curved surface of the object.
To reliably count clear objects moving on a high-speed conveyor line
Accurate ink level monitoring in printers in imperative to maintain optimal quality. If ink runs out and the printer keeps running, the end product will need to be thrown out. This increases costs not only due to the wasted raw materials, but also because of the cost of recycling or disposing of the paper.
To position all bottles in the same orientation for label application.
To sort various product by color.
To check for broken bottles on a conveyor
In applications where the liquid level must be monitored, a long range sensor is needed to ensure it can reach and sense the full depth of the tank for accurate monitoring. By sending a continuous signal that represents the current depth, the tank levels can be controlled with a pump in-pump out logic.
Plastic bags are manufactured in a continuous web, with a seal and perforation between bags. Since the plastic is clear, it can be very difficult for traditional sensors to detect the perforations between the plastic bags in order to determine when to separate them
To detect the presence of a registration hole on a printed circuit board
With highly automated processes in pharmaceutical industries, improper packaging can lead to disposal of thousands of products or down time. To avoid incorrect packaging or down time, a highly accurate sensor is needed to detect the position of a tube of cream or paste, in order to ensure tubes are oriented correctly before being sealed.
To measure thickness at three points across the width of a sheet of plywood
To detect liquid in a transparent tube, without touching the liquid
