Sensors used in automation are a topic that is becoming more extensive every year. There are even sensors that can recognize colors. It's not surprising, because even in smartphones we already have several sensors, especially in automated production workshops there may be dozens of them. In our article we will look at several types of sensors. These will be object detection sensors, as well as technological and capacitive sensors.Sensors for detecting metal objects and much more
The first type of object detection sensors are inductive sensors. The sensors discussed are used for non-contact detection of metal objects. These sensors generate a high-frequency electromagnetic field using a resonant circuit. When a metal object appears in the generated field, the device recognizes it. Magnetoinductive sensors work a little differently. This type of sensor responds to changes in the magnetic field. Sensors are used, for example, in commonly used cylinders, although there are models that are resistant to strong electromagnetic fields that can be used, for example, during welding. The sensors discussed are used to identify metal objects at a short distance. When there is a need to detect not only metal objects or it is not possible to install the sensor close to the production line, ultrasonic or photoelectric sensors are used.Technological and capacitive sensors
Among the process sensors, we can find a wide range of devices that monitor the quality of production processes. They control various physical quantities. Of course, the most popular are temperature sensors. In automated production, a conventional thermometer is not enough. Advanced sensors are able to measure temperatures from several tens to even several hundred degrees Celsius. Examples of such devices are sensors that provide temperature measurement in the range from -50 ° to +500 ° C. Other popular process sensors are pressure sensors and flow sensors. In turn, capacitive sensors are used to monitor granules, highly viscous media or for non-contact identification of metals or dielectrics. The sensors discussed are just a few examples among many other devices of this type that are used in industry and beyond. Advanced technologies, automated production lines, which are constantly monitored, not only make our work easier. Besides the fact that thanks to the production lines we can produce many more elements in a given time than we could do manually, thanks to various sensors, we are also confident in the quality of the products. escortannonce.net/escorts/geneve/
