UB500-Q30 24VDC 500MM Sensing Distance Ultrasonic Liquid Level Sensor with 4-20mA/0-10V / NPN/PNP

The UB500-Q30 ultrasonic proximity switch is a high-performance non-contact detection device that uses the principle of ultrasonic pulse reflection to accurately detect solids, liquids, powders, and transparent objects, with a detection range covering several centimeters to several meters, depending on the model. Its core advantages include millimeter-level measurement accuracy and high repeat positioning precision to ensure detection stability; a built-in temperature compensation system, suitable for a wide temperature range of -25°C to 65°C; IP67 protection rating, dust and water-resistant, suitable for harsh industrial scenarios; support for NPN/PNP switching and analog output, with detection distance flexibly adjustable via the TEACH button, compatible with various control systems. Typical applications include level monitoring, bottle counting, stack height measurement, and safety zone detection, especially suitable for industries with strict hygiene or explosion-proof requirements, such as food processing and corrosive chemical environments.

Working Principle

The ultrasonic proximity switch's transmitter emits high-frequency ultrasonic waves. When these waves encounter an object, they are reflected back. The receiver captures the reflected echoes, and by measuring the time it takes for the ultrasonic waves to travel from transmission to reception, and combining this with the propagation speed of ultrasound in air, the distance between the sensor and the object can be calculated. When the distance reaches a preset threshold, the switch outputs the corresponding signal.
