![]() Mega-sonic sensors operate based on the same principles as sonic and ultrasonic sensors, but are designed to detect acoustic waves or vibratory stresses at high frequency than ultrasonic waves. Piezoelectric Sensor Types: Ultrasonic Sensor (Credit: Billie Grace Ward 2014. It is important to note that ultrasonic sensors differ from ultrasonic transducers which are capa b le of generating their own ultrasound waves. The high-frequency operation of ultrasonic piezoelectric sensors, makes them capable of being utilized under a broad range of conditions, and for a variety of purposes. Piezoelectric ultrasound works on the basis of the piezoelectric effect whereby electricity is generated as a result of mechanical (vibratory) stresses created when acoustic waves interact with a material. This category of acoustic waves is often referred to as ultrasound. ![]() Ultrasonic piezoelectric sensor is used to detect acoustic waves that vibrate at very high frequencies above the audible range which is typically above 20 kHz. Ultrasonic Sensor (as one of the Piezoelectric Sensor Types) When these reflected signals are received, their characteristics can be analyzed to derive information about the objects that have been detected. The sensor may operate by emitting acoustic signals which are reflected back to the device on collision with objects in their path. Sonic sensors are used for a variety of purposes, among which geologic exploration is a prominent example. ![]() Sonic sensors are devices used to detect (and characterize) bodies or objects based on acoustic waves or vibrations released from the object.įor sonic sensors, the acoustic waves that can be detected by this piezoelectric device are those which fall within audible range. Sonic Sensor (as one of the Piezoelectric Sensor Types) This article discusses piezoelectric sensor types, as follows ġ). They are classified and distinguished based on acoustic capability, lead-connection design, and mode of operation. Piezoelectric sensor types are sonic, ultrasonic, mega-sonic, lead-type, pin-type, pressure, force, accelerometer, mechanical, and electrical sensors.
