Sensors & Transducers

We have a wide range of sensors and transducers to fulfil any application in industrial automation systems, from general purpose to RFID and IO-Link models. Our offer includes pressure, proximity, temperature and photoelectric sensors and transducers from leading brands such as SICK, Telemecanique Sensors, Omron, Pepperl + Fuchs, and RS PRO.

What is a sensor?

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:

  • Thermal sensor – specific temperature or a range
  • Proximity sensor – presence of an object Rotary encoder – position and speed
  • Flow sensor – force of fluid flow Pressure sensor - pressure

What is a transducer?

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:

  • Electrochemical: A battery converts chemical into electrical energy
  • Electromechanical: A motor converts electrical into mechanical energy
  • Thermoelectric: A thermocouple converts heat into electrical energy

What is the difference between a transducer and a sensor?

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.

What are the benefits of sensors and transducers?

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.

What are smart sensors?

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.
