Ultrasonic Level Switch Working Principle

S Bharadwaj Reddy
An ultrasonic switch is a device that uses inaudible high-frequency sound (ultrasound) to detect the presence or absence of a liquid at a designated point. The device consists of an

Air Filter Regulator Working Principle Animation

S Bharadwaj Reddy
Air Filter Regulator Air Filters are used to remove liquid water and particulate matter from compressed air sources. These are ‘mechanical filters’ and do not remove oil vapors or chemical
