1.The influence of ultrasonic propagation speed on rangingStable and accurate ultrasonic propagation velocity is a necessary condition to ensure measurement accuracy. The propagation speed of a wave depends on the characteristics of the propagation medium. The temperature, pressure, and density of t
Accuracy of ultrasonic ranging sensor module: ±(1cm+0.5%×distance), which is relatively low. The principle of ultrasonic ranging is to use the known propagation speed of ultrasonic waves in the air to measure the time when the sound wave encounters obstacles and reflect back after transmission, and
The working principle of piezoelectric ultrasonic sensor is mainly based on piezoelectric effect, which uses electrical components and other machinery to convert the pressure to be measured into electricity, and then performs relating measurement. Measuring precision instruments, such as many pres
1. Piezoelectric force sensor Piezoelectric force sensor is a industrial ultrasonic sensor that uses piezoelectric elements to directly realize force-to-electricity conversion. In tension and compression applications, two or more piezo quartz crystals are usually used as piezoelectric elements.
Ultrasonic sensors are widely used in manufacturing, electric power, and metallurgy to measure building materials, chemicals, food, automobiles, warehousing, ships, textiles, transportation, prospecting, liquid level, due to their high measurement accuracy, stable operation, and temperature compensa
