Capacitive sensors can detect solid, liquid or granular objects. These sensors can be used to detect highly structured and non-dimensionally stable objects, such as fill levels of liquids or bulk materials in direct contact with the medium or through a non-metallic container wall. They are also suitable for checking completeness. Capacitive sensors function reliably even in very dusty or dirty environments. Different designs and long ranges enable almost all areas of application in industrial automation. https://www.leuze.com/
Inductive sensors are the industry standard for non-contact detection of metallic objects. The Leuze portfolio includes a wide selection of standard and special sensors in a wide variety of designs, which have already proven themselves millions of times over for our customers. In particular, our extremely robust full stainless steel sensors, sensors with extended switching distances or even miniature sensors for extremely cramped installation conditions have already proven themselves many times in demanding applications. https://www.leuze.com/
Ultrasonic technology has a wide range of uses in many industries: An ultrasonic sensor emits a sound pulse and measures the time until the sound pulse reflected from an object returns to the sensor. The distance to the object can be precisely calculated using the principle of transit time measurement. The ultrasonic waves are reflected by the object, completely independent of the type of surface. That’s why sound-reflecting materials – shiny or reflective, transparent or very dark – do not pose a problem for reliable detection. Even products with difficult-to-detect geometries or fill levels of liquids, powders or granules can be checked contactlessly and very precisely using ultrasonic sensors. https://www.leuze.com/
The new cylindrical ultrasonic sensors in robust metal housings are particularly suitable for applications in the packaging or automotive industries. The compact HTU 208 ultrasonic sensors for object detection are characterized by a very narrow design (M8 threaded sleeve). They can also be installed in cramped production environments and detect fill levels with a narrow sound beam even through very small container openings. The HTU 212 buttons in the next larger design (M12) are used in confined environmental conditions when a greater range is required. The switching ultrasonic sensors HTU 218 (M18) are particularly easy to parameterize thanks to an IO-Link interface. https://www.leuze.com/
