The signal attenuates severely when passing through air, but the presence of liquid greatly enhances transmission. Thus signal strength of the ultrasonic burst serves as the sensing mechanism. Upon ...
AutomationDirect’s line of Flowline level sensors now includes point level switches to provide ultrasonic, vibrating fork, capacitive and buoyancy technologies for a variety of applications. Remote ...
Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...
