Tools of Industrial automation
Control systems are composed by five main elements:sensors,transducers,transmitters, controllers, and final control elements or actuators. A programmable controller, PLC or a programmable logic controller, is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines, amusement rides etc. The devices that convert a controller command signal into a change in a physical parameter are called Actuators.Whenever something must be moved, a motor is usually at the source of most automated equipment, which is controlled by a drive.
Supervisory control and data acquisition, in short known as SCADA, is a system that operates with coded signals over communication channels so as to provide control of remote equipment using typically one communication channel per remote station.
Influence of Sensors
A sensor is a device that converts a physical stimulus into a readable output. Integration of sensors into intelligent devices and systems has increased the capacity to measure, analyse, and aggregate data at a localized level. Autonomous and connected sensors are able to selectively sample and measure many physical properties. With the increasing cap
abilities of fixed-access and wireless networks, smart sensor developments allow the collection of raw data, which is processed into information and conveyed via a network connection.
The concept of sensor integration can be defined as an art of processing data from multiple sensors with an aim to replicate a physical environment or induce intelligence to control a phenomenon with increased precision and reliability. Recent advances in sensor technology and processing techniques, combined with improved hardware,make real-time fusion of data possible.
Fiber optic sensors and sensor heads allow for stable detection in any application, even for use in hazardous environments. For your area detection needs, specialized area sensors are there which can detection even slim or minute object.Temperature sensor is a device which gives temperature measurement as an electrical signal.
A frequently used practical applications of the temperature sensor is design of Industrial Temperature Controller for controlling temperature of devices used in industrial applications. Automatic Door Opening System is an application of PIR sensors which is used for automatic door closing and opening operations based on body movement near the door. PIR Sensor is an electronic sensor used for measuring the infrared light radiation emitted from objects in its field of view.
Proximity sensors are widely used in industrial automation fields. They are digital (on/off) sensors detecting the presence or absence of an object It is used in Conveyor lines for counting, jam detection and in machine tools for safety interlock, sequencing.
