Ultrasonic sensors

Ultrasonic sensors: function

Ultrasonic sensors are the Jack of all trades in the position sensors category, as they can measure powdered, liquid and solid objects using ultrasound.

Ultrasound is the term used for sound that is not perceptible to humans because it is higher than human hearing frequency. With ultrasonic sensors, position detection is carried out by the ultrasonic waves reflected by the object to be detected. The duration of the sound pulse is proportional to the distance. Ultrasonic sensors can reliably detect objects as well as measure levels, independent of many object properties. Even over longer distances, the sensors detect wire baskets and flat transparent glass panes.

Ultrasonic sensors are always used when photoelectric sensors are pushed to their limits.

In which areas of application are ultrasonic sensors used?

There are several areas of application, such as:

• Positioning and identifying products
• Detecting the presence of objects and people
• Distance measurement
• Loop control
• Level indication

Among the Automation24 sensor systems, you will find numerous ultrasonic sensors at low prices. One of the leading manufacturers on the market is microsonic, who specialiases exclusively in this product area.

Automation24 relies on industry specialists, among others, and offers ultrasonic sensors from microsonic. These include the pico+ series as a standard version and angle head variant, the mic+ series with switching and analogue outputs and the cuboid lcs+ sensors with a long range.

All these model ranges are also available with sustainable IO-Link interfaces (IO-Link smart sensor profile). The resulting benefits include seamless data exchange with other IO-Link capable systems and, last but not least, easier start-up, as well as extended maintenance and diagnostic options. They offer the ideal conditions for industry 4.0.

In addition, the zws series offers you the smallest cuboid sensors with teach-in buttons on the market.

Among the other microsonic products in the portfolio are the hps+ ultrasonic sensors with PTFE membrane and O-ring, as well as the crm+ sensors with tough PEEK film. Both series stand out due to their high chemical content and prove themselves in particular when they come into contact with aggressive mediums.

Furthermore, you can purchase high-quality ultrasonic sensors in the UGT series from manufacturer ifm. These metal sensors are especially robust, space-saving and easy to operate with the push of a button.

The portfolio of ultrasonic sensors on offer includes both square and cylindrical designs with high protection rating IP67 and scanning distances up to 6 m. This makes the sensors suitable for use in various areas. The outputs of the plug-in units on offer vary between programmable switching and analogue outputs. Some of the ultrasonic sensors have IO-Link interfaces. Simply select the appropriate device.
