Ultrasonic is a mechanical wave with a higher vibration frequency than sound waves. It is generated by the vibration of the transducer chip under the excitation of voltage. It has high frequency, short wavelength, small diffraction phenomenon, especially good directionality, and can be directed into rays. Dissemination and other characteristics. Ultrasonic waves have a great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. When the P+F Pepperl+Fuchs ultrasonic sensor encounters impurities or interfaces, it will produce significant reflections and form echoes, which can produce echoes when it touches moving objects. Doppler effect.

P+F ultrasonic sensor

Four types of P+F ultrasonic sensors: Pepperl+Fuchs ultrasonic sensor through-beam type, Pepperl+Fuchs ultrasonic sensor reflection, Pepperl+Fuchs ultrasonic sensor double paper detection, Pepperl+Fuchs ultrasonic sensor reflector. It has the characteristics of easy connection, long cylindrical shell length, high surplus, and strong anti-interference ability against dust and noise. The transmitter and receiver are installed relative to each other. If the sound wave is interrupted by an object, a switch value will be generated and the detection range will be large. The transmitter and receiver are in the same housing. Ultrasonic waves are directly reflected by the object, thereby detecting the object. Simple, concise sensor, the most commonly used type. The transmitter and receiver are separated, and their axes intersect. It can detect very small objects and is not sensitive to echoes outside the sensing area. The transmitter and receiver are placed in the same housing. The ultrasonic beam is reflected to the receiver through the fixed reflector. Advantages: Even objects that absorb sound waves or reflect very little can be detected. The P+F ultrasonic sensor is a sensor developed by using ultrasonic waves.
