Introduction Pressure is the force applied on a specific area. Pressure can be exerted by all forms of matter; solid, liquid and even gasses. Measurement

A pressure switch is a type of industrial sensor that can detect a certain amount of pressure, and open or close an electrical contact. There

Power supplies are used in almost every electrical/electronic application to provide sufficient current at a required voltage. There are two main types of power supplies:

In industrial environments such as manufacturing and heavy equipment handling, there are ‘keep-out’ zones. These zones are specially marked with bright colours to indicate limits

Laser distance sensors, also known as laser rangefinders, are optical distance measuring devices. They can measure the distance to a given object using a non-invasive

A rotary encoder is an electromechanical device used to monitor rotating objects like shafts and axles. Rotary encoders can be used to measure the position,

Introduction Relays are found in almost any machine that has an electrical system. From household appliances like washing machines and refrigerators to industrial applications such

In industrial applications, sometimes it may require measuring the position or the speed of a rotating object like a wheel or a shaft/axle. Rotary encoder

Through beam sensors, also the simplest type of photoelectric sensors. They are also called ‘opposed sensors’ due to their arrangement. The sensor consists of a

Solid State Relays (SSRs) are a substitute for electromagnetic switches such as relays. They have been introduced to mitigate the drawbacks that are inherent to

Introduction The detection of presence or absence of an object from a distance is called ‘proximity sensing’. Magnetic sensors have a special place among the
