Easy to clean: pms ultrasonic sensor

“A safe and easy-to-clean factory is the highest requirement in the production of medicines and food,” thus Johannes Schulte, Managing Director of microsonic. The technical components installed in production and packaging machines must withstand difficult ambient conditions and intensive cleaning processes.

Compact ultrasonic sensor with a sophisticated geometry in a number of versions. The unusual housing geometry of the sensor satisfies important demands placed on the hygienic design: whether top to bottom fill level measurement, or horizontal object measurement, a housing surface never has a horizontal alignment, despite installation position. This means that the cleaning fluids are able to run off completely, regardless of the installation situation.

With its stainless steel housing, the pms has been designed without crevices or dirt edges and is highly-suited to intensive cleaning and disinfection. Bacteria are unable to find any breeding ground on the smooth surface; cleaning agents flow away completely, irrespective of the installation position. The PTFE-encapsulated ultrasonic transducer protects the sensor membrane from aggressive chemical cleaning agents. Cables can be installed outside the process, to ensure a hygienic solution.

With four different detection ranges, the new pms ultrasonic sensor covers a broad measuring range of 20 mm to 1.3 m. The sensors are fitted with a Push-Pull switching output and IO-Link in the version 1.1 or with an 0-10 V or 4-20 mA analogue output. This covers a very broad spectrum of different applications.

The standard version of pms sensor with a D12 adapter shaft can be fitted in a mounting clip or a flange screw connection. The D12 bayonet catch enables sensors to the installed quickly and affordably in an established fastening system and can be replaced just as quickly without the need for tools.

Ultrasonic through beam sensor

Highlights

  • cylindrical and cubical housings
  • Emitter and Receiver separately
  • Installation-compatible with many light barriers ::: a true alternative for critical applications
  • Up to 500 Hz switching frequency

Cubic and cylindrical

Ultrasonic one-way reflective barrier for contact free detection of objects specially in the most diverse applications e.g. with bottles or plastic foils. ews sensors are available in cubical as well as cylindrical housing and are competitive with most through-beam light barriers.

Principle:

one ultrasonic sensor ews, set as emitter, sends cyclic sound impulses, received by another one, set as receiver. If an object interrupts the measuring track between the set transmitter and the receiver, the switched output of the receiver is set.

Well equipped: sks with IO-Link interface

Highlights

  • Available with IO-Link interface
  • Miniature housing with two M3 threaded sleeves
  • Installation-compatible with many optical sensors
  • Detection range 250 mm
  • microsonic Teach-in using a button
  • Brand-new temperature compensation

So small with IO-Link interface

sks ultrasonic sensors are the smallest, cuboidal sensors from microsonic and now available with IO-Link interface. The IO-link interface in our ultrasonic sensors provides everything in order to implement continuous communication all the way through system architecture right into the sensor. The sks sensor has a measurement range from 20 to 250 mm.

Chemical resistant ultrasonic sensors pico+TF

Highlights

  • Teflon membrane for protection against aggressive media
  • PVDF and PBT housing
  • Measuring range: 250 mm, 350 mm, 600 mm, 1,300 mm
  • Push-Pull switching output with IO-Link interface
  • Analog output 4-20 mA or 0-10 V

Compact in protective suit

pico+TF ultrasonic sensors are designed for filling level control of small containers due to its compact housing dimensions. The Teflon film protects the ultrasonic transducer against aggressive substances. The transducer itself is sealed againg the housing by a joint ring.

A small step for us. A great measurement range for you.

Two years ago, we presented the bks+6 with a measurement range of 35 mm. Sometimes, 35 mm is just not enough. We had a think and developed the cascadable transformer module. Their flexible and ingenious electronics enables them to be switched in series.

Fully customizable

At this year Hannover Fair, we present a sample of bks+8/37/FIU with a wide measurement range of formidable 320 mm. Due to this flexible concept other measurement ranges are conceivable. The IO-Link interface can be parametrized to detect a web edge, web width or the centre position of the web. It will be even possible to scan two webs simultaneously.
