Modern industrial manufacturing are sophisticated machines made up of several components, including hardware machinery, control electronics, sensors, drivers, controllers, motors, actuators, etc. All of which work together to ensure proper machining process to carry out advanced procedures and operations of a modern hi-tech machine used in manufacturing, automobiles, CNC, robotics, etc.
Sensors
We live in a world full of sensors all around us. If today's modern industrial manufacturing is concerned, the performance of the sensors has a significant impact on productivity, quality, reliability, and safety. Sensors form a link between the production equipment and the environment that provides feedback on the operations performed. Thus sensors are found in a very vast range of industrial systems applications, in which they play a crucial role. Electronic sensors, like sense organs in the human body, play a key role in robotics and artificial intelligence.
Function Of Sensor In Automated Machine
A sensor allows an autonomous industrial manufacturing machine to measure the geometric and physical characteristics of objects found nearby, Such as position, orientation, speed, vibration, distance, size, strength, moment, force, temperature, luminance, weight, etc.
Let Us Understand Some Sensors In Industrial Manufacturing
Rotary Encoders
A rotary encoder is the type of transducer used to measure rotational motion. It can detect a rotating shaft's motion and determine its position, speed, direction, and even acceleration. Rotary encoders typically employ optical or magnetic hall effect techniques.
Proximity Sensors
Proximity sensors detect the movement or presence of objects without physical contact and convert that information into an electrical signal. So when a contactless presence of an object is required, proximity sensors are used. The proximity sensor is primarily of four types.
Inductive Proximity Sensor - Inductive proximity sensors detect only metal objects and are contactless. When a metallic object approaches it, an oscillator drives a coil, which operates on the principle of induction.
Capacitive Proximity Sensors - Contactless capacitive proximity sensors detect metallic and nonmetallic objects, including liquids and powders. The capacitive proximity sensor contains a high-frequency oscillator and a sensing surface made up of two metal electrodes. When an object comes close to the sensing surface, it enters the electrostatic field of the electrodes, causing the capacitance of the oscillator to change.

Optical Proximity Sensors - Optical proximity sensors are made up of an infrared LED that emits infra ray light and an IR photodiode, which is- a light detector detecting reflection from an object when sensed. The amount of reflected light detected by the light sensor determines the object's position and distance.
Ultrasonic Proximity Sensors: - A transducer is used by the ultrasonic proximity sensor. It helps to send and receive high-frequency sound signals. If the transmitted sound gets reflected in the sensor, it determines whether or not the output circuit is activated.
Temperature Sensor
A temperature sensor is a simple electronic device used to measure temperature in a variety of industrial applications. Thermocouples, Thermistors, and RTD are the common types of temperature sensors. An RTD (Resistance Temperature Detector) is the most common device for measuring temperature in various industrial applications. RTDs are typically made with platinum, nickel, or copper wires because these materials have a positive temperature coefficient. That means when the temperature rises, so does the resistance.
To conclude today's modernized manufacturing process, we use a variety of sensors to fulfill customize demand and machine's working requirements. If you want to get more information about any other type of sensors please Whatsapp me at +91 9831092629.
