Ultrasoon sensors | Ultrasonic sensor

Ultrasonic sensors are sensors that work with sound waves at high frequencies that are not perceptible to the human ear. In ultrasonic sensors, an ultrasonic wave is sent through the transmitter. The reflection on an object or dust creates a reflection or echo of the sound wave. The distance can be determined by the time interval between sending and receiving the sound wave. In order to determine the correct distance, a geometric operation has to be carried out, for example a triangulation (triangulation). The speed is also dependent on the temperature. Depending on the accuracy of the transmitter and receiver, the ultrasonic sensor can be used in dusty, humid rooms.

Areas of application ultrasonic sensors

Ultrasonic sensors can be a useful alternative when optical sensors exceed their physical limits. This applies, for example, to objects or substances with uneven surfaces or under difficult environmental conditions or highly reflective liquid surfaces. Typical applications of ultrasonic sensors therefore control the presence of highly transparent films and the measurement of fill levels in liquid containers. A major advantage of ultrasonic sensors is the absolutely reliable suppression of the background as a result of their sound 'time-of-flight' principle.

COMPACT ULTRASONIC SENSOR WITH SOUND CONE CUBE SHAPE

The ultrasonic sensor with sound cone UT 20-S from Sensopart has a very compact cubic shape. The narrow sound cone allows objects to be detected through the smallest openings and drilled holes with a diameter of less than 5 mm.

Ideal sensor for special applications

This makes the ultrasonic sensor ideal for special applications, such as level measurement in microplate wells in medical analysis systems or for scanning printed circuit boards in the electronics industry. The ultrasonic sensor has a switching distance of 150 mm. The UT-20 variant has a switching distance of up to 700 mm. The ultrasonic sensors are available with different outputs: NPN / PNP, NO / NC, 0-10V, 4-20mA or an analogue output.
