WebThrough-beam sensors are the most accurate type of ultrasonic sensor. These sensors work by transmitting a beam of ultrasound waves across space. When the beam hits an object, it is reflected back to the sensor. These sensors are often used in industrial applications, where they can be used to measure the thickness of materials or the level of ... WebIn general, a narrow beam yields a greater detection range as the energy of the ultrasonic pulse is more focused and can go farther before dissipating to unusable levels. Inversely, a wider beam spreads that energy in a wider arc, reducing the expected detection range.

The object is detected when it breaks the emitted beam. The active area (A) of a through beam sensor is equal to the diameter of the lens of the receiver or emitter. The acceptance zone (B) of the emitter and receiver is larger.

WebOne method for accurately measuring the distance to targets is through the use of a laser triangulation sensor. They are so named because the sensor enclosure, the emitted laser and the reflected laser light form a triangle. The laser beam is projected from the instrument and is reflected from a target surface to a collection lens. WebWe would like to show you a description here but the site won’t allow us.
