Industrial Ultrasonic Sensor for Level, Distance & Object Detection
Voxintech supplies the industrial ultrasonic sensor range across India for non-contact level measurement, distance measurement and object detection. An ultrasonic sensor sends a sound pulse and measures the echo, so it works regardless of the target’s colour, transparency or surface finish – ideal for liquids, clear labels, glass, film and dusty environments where optical sensors struggle. Learn more about how an ultrasonic transducer works.

Ultrasonic Water Level Sensor
The most popular use of an industrial ultrasonic sensor is non-contact water level measurement in overhead tanks, underground sumps, rivers and open channels. The sensor sits above the water, needs no contact with the liquid and gives a 4–20 mA or 0–10 V signal proportional to level. See our dedicated ultrasonic water level sensor page for ranges, mounting and FAQs, or the oil level page for other liquids.
Choose an Industrial Ultrasonic Sensor by Sensing Range
Select a range a little larger than the maximum distance you need to measure. The minimum figure of each range is the blind zone – keep the target further away than this.
| Sensing range | Typical use | Models |
|---|---|---|
| 50–800 mm | Label and gap detection, small tanks, object presence | View models |
| 800–900 mm | Roll diameter, web loop and slack control | View models |
| 900–2200 mm | Tank level, bin level, stack height | View models |
| 2200–3500 mm | Overhead tanks, sumps, silos | View models |
| 3500–6000 mm | Large tanks, channels, vehicle detection | View models |
| 6000–8000 mm | Deep tanks, rivers, dams and long-distance measurement | View models |
Industrial Ultrasonic Sensor Applications

Which Industrial Ultrasonic Sensor Output Do You Need?
- PNP + 4–20 mA – continuous level or distance to a PLC or indicator, best for long cable runs
- PNP + 0–10 V – continuous measurement to controllers with a voltage input
- 2 × NPN – two switching points, e.g. high and low level or pump on/off
Frequently Asked Questions
What is an ultrasonic sensor used for?
An industrial ultrasonic sensor measures distance or detects objects using sound waves, without contact. Common uses are liquid level measurement, label and object detection, roll diameter measurement and position sensing.
Can ultrasonic sensors detect transparent objects?
Yes. Because they use sound rather than light, ultrasonic sensors reliably detect clear labels, glass bottles, PET and film that optical sensors often miss.
What is the maximum range?
Voxintech ultrasonic sensors are available with sensing ranges up to 8 m.
Do you supply across India?
Yes. We supply from Delhi NCR to customers across India and overseas. Share your application, range and output and we will recommend the right model.
