This type of piezoelectric ultrasonic sensor small power ultrasound probes is used for detection. Ultrasonic sensors are widely used in industrial, defense, biomedical and other fields.Ī commonly used ultrasonic sensor consists of a piezoelectric wafer that can emit both ultrasonic waves and ultrasonic waves. When an ultrasonic wave hits an impurity or an interface, it produces a significant reflection to form a reflected echo, which can produce a Doppler effect when it hits a moving object. Ultrasonic penetration of liquids and solids is great, especially in sunlight-opaque solids. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directionality, and can be directional and propagated. Ultrasonic waves are mechanical waves with vibration frequencies above 20 kHz. Ultrasonic sensors can be divided as an open ultrasonic sensor, waterproof ultrasonic sensor, and high-frequency sensors. Recommended ultrasonic sensor manufacturersĪn ultrasonic sensor is a sensor that converts an ultrasonic signal into another energy signal (usually an electrical signal).Īccording to the use of methods, Ultrasonic sensor can be divided into broad categories: transmitters, receivers, and transceivers.Disadvantages of ultrasonic sensors and solutions.Choose the ultrasonic sensor detection method.What is an ultrasonic sensor system constitution.What is the working principle of an ultrasonic sensor.What are typical applications of ultrasonic sensors.If you choose our industrial ultrasonic sensor, we will not only deliver standard industrial ultrasonic sensor but also provide a modified industrial ultrasonic sensor or customized industrial ultrasonic sensor solutions. We will never compromise our commitment to pursuing industrial ultrasonic sensor quality, reliability, and durability. PD Ceramic works closely with our selected and proven partners. Our industrial ultrasonic sensor consists of a high-frequency piezoelectric transducer, ranging from 70 kHz to 400 kHz. Our industrial ultrasonic sensor is a sort of high-frequency piezoelectric transducer. This type of industrial ultrasonic sensor is more precise and exhibit higher immunity to ultrasonic noise.

Industrial sensors with frequencies from100 kHz to 300 kHz can be labeled as ultra-high frequency sensors. Piezo: Your Leading Industrial Ultrasonic Sensor Manufacturer Our industrial ultrasonic sensor is referred to as piezoelectric ultrasonic sensor or piezo ultrasonic sensor, which uses the piezoelectric effect to measure changes in pressure, humidity, temperature, strain or force by converting them into an electrical charge. Piezoelectric ceramics perfectly matches to this domain application requirements. Ultrasonic sound waves work well in nature and are now applied in industrial, medical and related scientific research as well. Usually, frequencies higher than 20 kHz, which is above the human hearing can be recognized as ultrasonic. We offer the most innovative and cost-effective industrial ultrasonic sensors that meet the varying requirements in the industrial ultrasonic sensor market. PiezoData Inc.(PD ceramics) – Your competent partner forindustrial ultrasonic sensors. Initially, these were designed for sleep sensors, to be placed underneath a mattress to detect how much the sleeper shifted around through the night.Ĭomes with a dual metal contact tab with 0.2" spacing between the two contacts, on one end.PiezoData Inc.: Reliable Industrial Ultrasonic Sensors Expert Like perhaps a wearable project with a sensor sewn into clothing, or feedback for a robotic actuator. There could be some unique sensing projects that need to sense over a long, flexible distance. Usually, piezos are round hard disks, which is why we thought this thin and flexible version was interesting.

If a 1 Mega-ohm resistor is placed across the two terminals you will see the current converted into a voltage that can be read by an analog-to-digital converter (ADC).īasically, connect one tab to ground, another tab to the ADC input of your microcontroller or ADC, and a 1M resistor across both, then read the analog input while touching/poking/twisting the piezo element and you'll see little spikes of voltage whenever the piezo has vibrated. Piezo film can be used to detect motion or vibration - when shifted around or touched, it creates a small current pulse across the terminals. This thin silvery ribbon is an interesting sensor. It's made of 2mm wide by 600mm long piezoelectric film sandwich.
