Compact ultrasonic sensors for challenging applications
New switching and measuring ultrasonic sensors
Ultrasonic sensors are problem solvers for challenging detection and measurement tasks. They are used wherever conditions are not ideal for optical sensors. For example, when detecting objects with sound-reflecting surfaces or in harsh, dusty or vaporous production environments.
The ultrasonic technology ensures a broad range of applications in many different industries: An ultrasonic sensor emits an acoustic pulse and measures the time the acoustic pulse reflected by an object takes to return to the sensor. The principle of propagation time measurement is used to precisely calculate the distance to the object. The ultrasonic waves are reflected by the object, completely irrespective of the type of surface. This means that sound-reflecting materials – glossy or reflective, transparent or extremely dark – do not hinder reliable detection. Products with hard-to-identify geometries or fill levels of liquids, powders or granulates can also be checked contactlessly and extremely precisely using ultrasonic sensors.
The new cylindrical ultrasonic sensors in robust metal housings are particularly suitable for applications in the packaging or automotive industry. The HTU 208 compact ultrasonic sensors for object detection are characterized by their extremely slimline design (M8 threaded sleeve). They can also be installed in confined production environments and detect fill levels using a narrow sound cone, even through very small container openings. The HTU 212 sensors in the next larger design (M12) are used in cramped ambient conditions where a high operating range is required. Thanks to their IO-Link interface, the HTU 218 switching ultrasonic sensors (M18) are extremely easy to configure.
The measuring ultrasonic distance sensors of the DMU 218 series with analog output have been developed for precise distance measurement. The switching and measuring ultrasonic sensors with M30 design achieve operating ranges of up to 6 meters. An IO-Link interface enables quick and easy operation of the sensors.
