Ultrasonic sensor ranges cover diverse applications

Balluff is expanding its range of ultrasonic sensors for non-contact measurement of heights and fluid levels, and for loop control; these sensors can also count and monitor the presence of objects. Because they are not affected by dust, dirt and mist they are suitable for critical applications.

Thanks to the inbuilt display, the BUS M30M ultrasonic sensors are said to be particularly simple to operate. Full numeric pre-setting of the sensor is possible and then, during operation, the display shows the measured values in either mm/cm or as a percentage. The sensor family comprises five variants and, with a measuring range from 30cm to 8m, covers a wide variety of applications.

All variants are available with one or two switching outputs, an analogue current and voltage output, or as a combination with switching and analogue output. The sensors can be used in multiplex operation as well as being automatically synchronised to prevent them from influencing one another.

With a housing length of just 41mm, the BUS M18M series ultrasonic sensors are very compact. A narrow sound cone and a blind zone of just 20mm make the sensors very versatile. Two housing variants – straight and with a 90-degree head – are each available with four scanning ranges of up to 1.3m.

A highlight of these sensors is the IO-Link interface, and there are also variants with push–pull switching outputs or 4-20mA or 0-10V analogue outputs.

Also new from Balluff are the compact BUS R06K ultrasonic sensors that feature a rectangular housing and high resolution. For challenging measurement tasks, two versions can be upgraded with an attachment waveguide. This enables measurements to be made in boreholes and in openings with diameters greater than 5mm. For simultaneous operation of up to 10 sensors in a constricted space, the series is equipped with a synchronisation input. The wide range of variants with switching output or with current or voltage analogue output in five operating scanning ranges makes the sensor family suitable for a very wide range of applications.
