What are Ultrasonic Sensor?

Ultrasonic sensor are also called ultrasound sensor, used to calculate the distance to or presence of an object by sending a vibration of sound, called ultrasound, within human hearing range towards the object and then measuring the time it takes for the sound to recover. Knowing the speed of sound, the sensor determines the distance to the object and sets its power. 

Sensor outputs are determined based on measured distances or overflow conditions, lack of target detection, or user-selected response algorithms. Outputs can be:

  • analog voltage or current signals proportional to the measured distance
  • switches or relay contact closures that open or close after a certain distance
  • distance data sent as serial data.

What is the Range of Ultrasonic Sensors?

The ultrasonic sensor radiates pressure waves of sound energy at frequencies of 25-50 KHz, which is above the range of human hearing. Most ultrasonic sensors work with pulse waveforms that detect the presence of a vehicle and measure its speed.

The range of ultrasonic sensors generally varies according to their design and application. In general, the range can be classified as follows:

  • Short-range ultrasonic sensors:

Range: up to 1 meter (about 3.3 feet)

Applications: object detection, obstacle avoidance in robotics, and level measurement in small containers

  • Mid-level ultrasonic sensors:

Range: 1-5 meters (about 3.3-16.4 feet)

Applications: Distance measurement, industrial automation and parking radar systems.

  • Long-range Ultrasonic Sensors:

Operating range: 5-10 meters (about 16.4-32.8 feet)

Applications: Wide-range height measurement, long-range target detection and some types of environmental monitoring.

  • Extended Range Ultrasonic Sensors:

Range: More than 10 meters (more than 32.8 feet)

Applications: Special industrial applications, large tank level monitoring and long-range proximity detection.

How can you mount the sensors?

The following general sensor mounting guidelines should be adhered to. If you want to know more about the complex ultrasonic mounting guidance, feel free to contact Unseen ERA Customer Service.

  • It is recommended that ultrasonic sensors be installed using plastic threaded adaptors to prevent the absorption of acoustic energy through the sensor body.
  • Never use a wrench on the sensor body; instead, sensors should only be hand-tightened.
  • When tank mounting to a domed or round tank, adjust the sensor mount until the transducer face is square with the target surface.
  • Install the sensor at a flange opening directly on the tank ceiling. If a riser is installed, it needs to be big enough to prevent reflections from the inner walls. The riser’s lower edge should be rounded off.
  • Provide a sun shade for outside installations to prevent the sensor body from overheating and causing erroneous measurements. The body of the sensor should stay equal to the ambient air temperature so the sensor’s built-in temperature balance can function accurately.


To sum up, everything that has been stated so far, the above-provided information regarding “What is the Range of Ultrasonic Sensors” concludes that the range of these sensors may vary from 2 meters to 10 meters depending on the type of ultrasonic sensor and the factors.
