Understanding the Blind Zone of Ultrasonic Level sensors: Key Influencing Factors and Solutions
Industrial grade ultrasonic level sensor has become essential tool for industrial level monitoring due to their non-contact measurement, high accuracy, and broad applicability. However, their performance is limited by the "blind zone"—an area near the probe where accurate level detection is impossible. This article explores the causes, influencing factors, and solutions for blind zones, while introducing the PWL-U201 Ultrasonic Level Sensor, an advanced solution for complex industrial environments. Definition and Principles of the Blind Zone The blind zone refers to the area near the probe where measurements are unreliable due to overlapping transmission and reception of ultrasonic pulses, akin to a visual blind...
