A sensor is able to detect and measure different types of energy and transform it into a readable output. Here are some example of types of sensors and their measurement:
A transducer is a device that converts an input energy type from one to another. In the case of a light bulb, electrical energy is converted into both heat and light outputs. The following are some examples of transducer types:
A transducer simply converts input energy into a different output energy type. However, while a sensor is similar to a transducer by reacting to a change and providing an output electrical signal, it is in a readable format that can be quantified.
When sensors and transducers are utilised in efficient automated systems, they enable improvements in operational reliability, give greater control over quality through high accuracy, as well as optimising productivity and safety.
As Industry 4.0 and the Internet of Things (IoT) are revolutionising and advancing automated systems. IO-Link is a recognised global networking standard for sensors that allows machines from different manufacturers to communicate with each other. Smart sensors carry out the same measurement applications as regular sensors with additional control through smart capabilities such as self-identification, testing, validation, and learning. They help to provide live data, establish communication between machines and react on their own to diagnose and correct issues to improve efficiencies.
