When your application requires a dependable method of detecting objects, measuring distance, or monitoring fill levels, non-contact ultrasonic sensors are an ideal solution. However, it can be confusing and complicated to understand how ultrasonic technology works, comprehend the theory behind them, and decide which device is best for your sensing application. The experts at elobau are here to help. We provide knowledge and resources on all our products and manufacture high-quality ultrasonic sensors for any industrial use.

What is Ultrasonic Sensor Technology?

Ultrasonic sensors operate similarly to radar technology, discharging a series of sounds to measure the distance between the sensor and an object. This differs from other level sensor solutions, like fuel level sensors, capacitive level sensors, and float level sensors, which may use infrared or other detection methods. Because of ultrasonic sensing technology’s versatility and durability, ultrasonic sensors can be used as a viable alternative to many level sensors in most industrial applications.
 

The Principles, Applications & Limitations of Ultrasonic Sensors

Ultrasonic sensors are made up of transmitters, receivers, and transducers. The sensor’s head emits a high-frequency sound pulse, also known as the ultrasonic waves, and receives the wave reflected back from the target it’s sensing. Ultrasonic sensors are generally utilized as proximity sensors and, depending on the type, work in harsh environments to detect a wide range of surfaces and materials. Limitations include blind zones, cross talk, and others.

Ultrasonic Technology Operating Modes

Ultrasonic technology comes with various sensor modes to meet the needs of any industrial application. Each mode features its own strengths, limitations, and configurations. Explore some of the most common modes for ultrasonic technology and determine which mode or ultrasonic sensor best suits your planned level sensing application. Modes include:
  • Diffuse
  • Retroreflective
  • Single point
  • Hysteresis
  • And more.

Installing Your Ultrasonic Level Sensor Technology

Ultrasonic sensors must be properly installed to measure distances and levels effectively. The environment, space available for mounting, and material measured will impact your ultrasonic technology’s installation requirements. Our experts discuss these and other installation considerations for ultrasonic sensors and outline common mistakes that can affect the performance and lifespan of your sensor system.
