Ultrasonic sensors for a wide range of duties
04 February 2013
Ultrasonic sensors from Balluff are available for contact-less measurement of fill levels and distances, as well as counting and monitoring the presence of objects, even in dusty, dirty and misty conditions.
The BUS M30M series ultrasonic sensors (pictured) are simple to operate, thanks to an integral display that allows full numeric pre-setting of the sensor. During operation, the display presents all 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 either 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 automatically synchronised to prevent them from influencing one another.
With a housing length of just 41mm, the compact BUS M18M series features a narrow sound cone and a blind zone of just 20mm. Two housing variants - straight and with a 90 degree angle head - are each available with four scanning ranges of up to 1.3m. These sensore feature an IO-Link interface, and there are variants with a push-pull switching output or analogue 4-20mA/0-10V outputs.
The small, high-resolution BUS R06K ultrasonic sensors, offered in rectangular housings, are available in two versions thet can be upgraded with an attachment waveguide. This allows measurements to be made in boreholes and in openings with diameters greater than 5mm.
For simultaneous operation of up to ten sensors in a constricted space, this series is equipped with a synchronisation input. There is a wide range of variants, with switching output or with current or voltage analogue output in five operating scanning ranges.
