Ultrasonic sensors

How to choose this product

An ultrasound sensor detects the presence of ultrasound waves, those with a frequency between 18 kHz and one GHz, beyond the range of human hearing.

It can be used for industrial measurements by detecting ultrasound waves which have passed through a particular physical environment. This allows the device to measure fluid flow rate through a pipe, for example. Ultrasound transducers, which both sending and receiving capability, can detect container fill levels. The emitted pulses are measured as they bounce back from a target surface.

Applications

These sensors are found throughout industry, primarily as presence and distance detectors. They also measure temperature, pressure, concentration and flow rate, as well as continuously detecting fill levels.

Technologies

Distance measurements are made by emitting conical pulses, which bounce back from any vertical surface. The transducer measures the time between signal emission and reception, and uses this data to calculate the distance to the object.

How to choose

Choice will depend on whether the sensor will be used to measure flow, level or another parameter. To ensure accuracy and reliability, the operating environment also must be taken into account.

Advantages

- No-contact operation
- Reliable
- Unaffected by surface color or structure
- Not expensive

Disadvantages

- Temperature-sensitive
- Affected by turbulence
- Surface foam can falsify readings
