Digital Ultrasonic Distance Sensor WUB3000 for Machine Positioning

1. Why You Need It

Glass cutting machines, edge polishers and automated equipment need non-contact distance measurement to position workpieces and control travel — and ultrasonic sensors deliver that reliably without touching the object. This digital ultrasonic distance sensor (WUB3000) measures 200-3000 mm with a 100 kHz transducer and 200 ms response, providing stable distance data for machine positioning, level detection and object presence sensing across a wide temperature range.

2. Working Principle

The sensor emits a 100 kHz ultrasonic pulse and measures the time for the echo to return from the target surface, converting that time into a distance reading. The 200-3000 mm detection range and 200 mm blind area define its measurement window, while the 200 ms response delay provides steady, stable readings. The sensor operates in sync mode (≤20 Hz) to avoid interference from adjacent sensors.

FAQ

Q: What is an ultrasonic distance sensor?

An ultrasonic distance sensor measures distance by emitting a high-frequency sound pulse and timing the echo reflected from the target. It provides non-contact distance measurement, which is ideal for positioning workpieces and detecting objects on machines and automated lines.

Q: What is the detection range?

The detection range is 200-3000 mm, with a 200 mm blind area closest to the sensor. This provides a wide measurement window for machine positioning, level detection and object presence sensing.

Q: Why is it non-contact?

Ultrasonic sensing uses sound waves, so the sensor does not touch the target. This eliminates mechanical wear, making it long-lasting and suitable for fragile or moving targets such as glass sheets.

Q: Can it detect transparent objects like glass?

Yes. Unlike optical sensors, which can fail on transparent or reflective surfaces, ultrasonic sensors detect any surface that reflects sound, including glass and clear materials. This makes them ideal for glass cutting and polishing machines.

Q: What is the transducer frequency?

The transducer operates at approximately 100 kHz, a frequency suited to short-to-medium distance measurement with good resolution and reliable echo detection.

Q: What is sync mode for?

Sync mode (≤20 Hz) coordinates the firing of multiple ultrasonic sensors so they do not interfere with each other. This is important when several sensors are mounted close together on a machine.

Q: What is the response delay?

The response delay is about 200 ms, providing stable, filtered distance readings. This is suitable for machine positioning and level control where a steady signal is preferred over rapid fluctuation.

Q: What temperature range does it cover?

The media temperature range is -40 to 80 °C, allowing operation in cold and hot environments typical of industrial machinery and outdoor installations.

Q: How is it mounted?

It is mounted on the machine or conveyor frame facing the target surface, within the 200-3000 mm detection window and outside the 200 mm blind area. The output connects to the machine's controller.

Q: Where is it used?

It is used on glass cutting machines, edge polishing machines, automated stacking stations and conveyor systems. It provides reliable, non-contact distance and object detection for machine positioning.
