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.
