The P+F Pepperl+Fuchs ultrasonic sensor has a great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. It can penetrate to a depth of tens of meters. When the ultrasonic wave hits the impurity or the interface, it will produce a significant reflection to form an echo, and it can produce a Doppler effect when it hits a moving object. Therefore, ultrasonic testing is widely used in industry, national defense, biomedicine, etc.

P+F Pepperl+Fuchs photoelectric switches can be divided into opposite-beam type; diffuse reflection type; specular reflection type; slot type photoelectric switch; optical fiber type photoelectric switch, etc. The important function of the photoelectric switch The important function of the photoelectric switch is to be able to handle the change of light intensity: use the light beam to reflect the object; make the light beam return instantaneously after a long distance. . Ultrasonic probes are mainly composed of piezoelectric wafers, which can transmit and receive ultrasonic waves. Low-power ultrasound probes are mostly used for detection. It has many different structures, which can be divided into straight probe (longitudinal wave), oblique probe (transverse wave), surface wave probe (surface wave), lamb wave probe (lam wave), double probe (one probe reflection, one probe reception) Wait. The working frequency is the resonance frequency of the piezoelectric wafer. When the frequency of the AC voltage applied to its two ends is equal to the resonance frequency of the chip, the output energy is the highest and the sensitivity is the highest. Ultrasonic is a kind of mechanical wave with higher vibration frequency than sound wave. 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 directivity, which can be directed into rays. Dissemination and other characteristics.
