Pepperl + Fuchs sensor sensor among the elite warriors

P+F ultrasonic sensor can determine its waveform through the use of acoustic wave guiding devices. This device is installed on the transmitter of the receiver, sometimes also on the transmitter. After installing this device, the receiver will react weakly to the sound waves coming from the side, so it can detect small objects more reliably. After the AC voltage is supplied, the ultrasonic generator will vibrate.

The vibration alternately compresses and strikes air molecules to continuously transmit ultrasonic waves, and the ultrasonic generator can also receive ultrasonic echoes. Pepperl+Fuchs ultrasonic sensors are divided into electrostatic and piezoelectric types according to their generators. Electrostatic sensors are used for long-distance detection, usually up to 6-7 meters. This long-distance sensor is often used to detect the liquid level of a large container, etc. Piezoelectric sensors usually have a short detection distance, generally around 1 meter, but they are well sealed and can be used in harsh environments. Some sensors have an adjustable detection window or analog output, which can output a voltage/current value proportional to the distance of the measured object. The digital filter can make the sensor have the ability to resist electromagnetic or other acoustic interference, the analog output has a high linearity, and the sensor with temperature compensation is suitable for occasions where the ambient temperature changes greatly. In the ultrasonic proximity sensor, there are also products where the ultrasonic generator and the controller are separated. These small ultrasonic generators can be installed in a small space, and are detected and output controlled by the controller. The through-beam ultrasonic sensor has an independent transmitter and receiver, and is an ideal product for detecting transparent objects.
