How Limit Switch Works ?
Presence Sensing is the act of detecting the presence or absence of an object with a contact or non-contact sensing
Switches
Instrumentation Switches used in measurement and control systems. The purpose of a switch is to turn on and off with varying process conditions.
Microwave Barrier Level Switch Working Principle
Non-contact point level detection in bulk solids In many cases where contact methods are limited, microwave barriers are the appropriate
Vibration Switch Working Principle
A vibration switch is a device that recognizes the amplitude of the vibration to which it is exposed and provides
RF Level Switches Working Principle
RF level sensors are the Capacitance level detectors which are sometimes called as admittance level sensors. These sensors make use
Relays in Ladder Logic Tutorials
Electromechanical relays may be connected together to perform logic and control functions, acting as logic elements much like digital gates (AND,
Relay Principle & its Types
A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating
Reed switch Working Principle
The reed switch is an electrical switch operated by an applied magnetic field. It was invented at Bell Telephone Laboratories
Two Wire Sensor Working Principle and Animation
Sensors can also be broken down by their wiring configurations. The most common are 2-wire and 3-wire. Two-wire devices are
Proximity switches Circuit Diagram Operation
A proximity switch is one detecting the proximity (closeness) of some object. By definition, these switches are non-contact sensors, using magnetic,
Pushbutton switches and Types of Switches
A hand switch / Pushbutton switch is exactly what the name implies: an electrical switch actuated by a person’s hand motion.
