How do ultrasonic sensors work?

Ultrasonic sensors emit high-frequency sound waves and measure the time for the echo to return from a target. This allows distance measurement independent of the target's color, transparency, or surface finish. Carlo Gavazzi ultrasonic sensors provide reliable detection where optical sensors may fail.

What applications are ultrasonic sensors used for?

Common applications include liquid level measurement in tanks, roll diameter monitoring, stack height detection, vehicle detection, distance measurement, and presence sensing of irregular or transparent objects. They excel in dusty environments where photoelectric sensors would require frequent cleaning.

What is the detection range of ultrasonic sensors?

Carlo Gavazzi ultrasonic sensors offer ranges from 50mm to several meters depending on the model. Short-range versions are suitable for precise positioning, while long-range models work well for level detection in large tanks or distance measurement applications.

FAQ Library Product Brochure Carlo Gavazzi’s UA Series ultrasonic sensors are designed for both distance measurement and object detection in tough environments. The range consists of both M18 and M30 housings. Discrete output types are available for presence and absence detection, and are ideally suited for detecting objects,such as transparent objects, that cannot be reliably detected by other sensors.

Analog output types are available on our ultrasonic sensors for applications requiring a measurement of the target object, such as detecting the level of fluid in a tank. The Analog models have your choice of 0-10 VDC or 4-20 mA outputs.

Our more advanced ultrasonic sensor models incorporate teach functions, which allow the set-points to be configured with the push of a button, and via Windows-based software for applications where greater control of sensor parameters and variables is required. The Windows version also allows for settings to be saved and downloaded to multiple ultrasonic sensors.
