What is it ?
It is among the main sensors used in the industry, due to its versatility and practicality of installation. The ultrasonic sensor is a device that uses high frequency sound in distance measurement and also detection of various materials.
Operation
In fact the technology tries to imitate nature, similar to the sonar of bats, the ultrasonic sensor has as a principle the emission of a high frequency sound wave, this sound wave hits the object to be detected and returns. The difference in sound waves is converted into an electrical signal.
The electrical signal can be digital 24VDC or even analog signal 4 to 20mA.
Applications
- Measure levels.
- Product volumes (pasta, powders, granules and liquids).
- Positioning objects.
- Pulp and Paper.
Final Observations
The ultrasonic sensor is widely used to measure long distances and also environments with dust cloud (making it impossible to use the optical sensor).
It is also worth mentioning that the ultrasonic sensor has the so-called dead zone, which are the reading limits of each sensor.
Each limit is described in the manufacturer’s manual.
