Level measurement using ultrasound – reliable and versatile

With its 2U Industry ultrasonic sensor, the Leutkirch based global manufacturer of industrial and off-highway applications, offers a reliable and convenient way to measure fill levels and detect objects. Thanks to its high level of variability and flexibility, the sensor is suitable for almost any kind of fill level application. Regardless of the transparency, gloss, surface characteristics and colour of the fluid or material, the 2U Industry sensor delivers precise results, even in adverse industrial environments. Setup
is quick and easy. The ultrasonic sensor is a contactless measuring device, i.e., no moving or mechanical parts during measurement, meaning minimum maintenance requirements for the operator. 

In focus: Flexible use and easy operation 

As far as the output signals are concerned, the user can choose between an analogue current signal or voltage signal. Furthermore, up to four freely programmable switching outputs (high side/low side) are available. Primarily developed for measuring the level of liquid media and solids
such as granulates, the ultrasonic sensor is also suitable for distance measurement to objects, walls or the ground. The user can carry out continuous fill level and limit level measurements.

Parameterisation of the sensor is menu driven using the display and a push button (teach in button). The easy-to-read display indicates the fill level. The rotatable head of the sensor ensures that the display is always clearly visible. It also provides additional flexibility when mounting at awkward installation
positions. The sensor is available in variants with G 1.5", G 2?, 1.5? NPT and 2? NPT mounting threads. The 2U Industry sensor is suitable for applications with an operating range of the of up to 1m and the ambient temperature is between -20°C and +70°C.

Added value thanks to ultrasound

The principle of ultrasonic technology is as easy as it is effective. Ultrasonic sensors cyclically emit sound pulses in the high frequency ultrasonic range towards the target
object. The target object reflects the signal, which the sensor receives again as an echo. The propagation time is then used to calculate the distance. This measuring principle not only allows distances to be measured, but also the positions of objects to be detected – even during precipitation, in humid, dusty and smoky conditions, and at extreme temperatures. This makes the ultrasonic sensor an all-rounder that is suitable for a variety of measuring and monitoring tasks.
