Ultrasonic Sensors 

Q: What are ultrasonic sensors used for?

A: Ultrasonic sensors are usedfor the reliable detection and measurement of objects, independent of their material, color, transparency and texture. Examples include:
ultrasonic reflex sensor

  • Transparent and dark objects
  • Reflective surfaces
  • Shiny objects 
  • Bulk materials and liquids

Ultrasonic waves of a certain frequency are pulsed to determine the object's distance from the duration of the ultrasound that it reflects. The measured value is output as either of the following two options: 

  1. Voltage value (0...10 V/4...20 mA) or 

  2. Digital form (IO-Link)

Some of the Wenglor ultrasonic sensor features will determine what is the use of ultrasonic sensor. Features include:

  • Almost completely insensitive to interfering factors (e.g. extraneous light, dust, smoke, mist, vapor, lint, oily air, etc.)
  • Easy to use
  • Excellent technical properties

What Applications Are Ultrasonic Sensors Used For?

Below is a list of the applications the Wenglor ultrasonic sensor can be used for (depending on the product):

Ultrasonic Reflex Sensors

  • Distance monitoring
  • Fill level measurement (min./max.)
  • Measuring of bulk solids
  • Measuring stacking height
  • Slack monitoring
  • Quality testing
  • Sag control for sheet products
  • Position and presence monitoring
  • Object selection
  • Steel coil measurement
  • Distance & collision protection
  • Detection of dark objects
