A sensor is a type of component which is used to either detect or measure input relative to its application. Many sensors will then act or react to the input depending on their main purpose.
The input could be a range of different matters, a few examples are;
The output measured by the sensor is usually converted into a readable format for the user and shown on a display.
To measure the different inputs, different sensors are used. They come in many different shapes and sizes to suit the different uses and application requirements.
You will notice that we are surrounded by sensors; smart phones, laptops, light switches, coffee machines, elevators, heating controls - the list goes on. This guide gives a brief overview of different types of sensors on the market today and what they are used for.

There are two main types of pressure sensor; pressure transducers and pressure switches.
Pressure switches are programmed to a limit and will “switch” off or on when that limit is reached. Typical application examples;
Pressure transducers give readings of the actual pressure within a given environment. Typical application examples;

Position Sensors are used to measure the position of a given object. This can be in a linear motion (up and down or side to side) or a rotary motion (round). They use either contacting or non-contacting technology depending on the requirements of the application.

Temperature sensors come in a whole array of sizes and shapes and are highly diverse. Temperature probes, NTC thermistors, RTD sensors, thermocouples - are just some of the products within our range.
Many temperature sensors use resistance as an indicator of temperature. They are often wired into an electrical circuit measuring the resistance of the electricity being passed through the element.
Application examples of temperature sensors;

Sensors used to measure weight are referred to as load cells or force sensors. There are many different types of load cells, they measure weight based on the amount of compression which is detected by the sensors within the cells. Very often strain gauges are used for this process.
Different types of load cells are suitable for different capacities.
Some common applications for load cells are;
Other applications include;
