World's smallest ultrasonic sensor in solid stainless steel
Published: 27 December 2015 - Lisa Peake
The UMB800 from Pepperl+Fuchs is the world's smallest ultrasonic sensor in solid stainless steel. It is made entirely from FDA-compliant materials. With its large detection range and highly compact design, it opens up new automation possibilities in hygienic applications.
The new sensors in the UMB800 series feature hygienic housing that is made entirely from V4A stainless steel. The surface roughness of the housing is less than 0.8µm, minimizing the risk of microbial contamination. The outer skin is hermetically sealed and free from gaps. The sensor can withstand steam jet treatment and aggressive cleaning agents. It features IP68/IP69K degrees of protection and ECOLAB certification. No cleaning processes need to be changed when the sensor is installed in existing systems.
At 18mm in diameter and 55mm in length, the UMB800 is the world's smallest ultrasonic sensor in solid stainless steel. The compact design does not reduce its performance: It provides an exceptionally wide measuring range from a dead band of only 70mm and a detection range of 800mm.
The sensor complies with the guidelines of the European Hygienic Engineering and Design Group (EHEDG). All materials are FDA-compliant. The certification covers its specially developed hygienic mounting bracket. No tools are required for assembly. The sensor is resistant to significant temperature fluctuations and remains functional at a continuous operating temperature of up to 85°C.
The UMB800 series is primarily designed for use in hygiene applications (food and pharmaceuticals). It demonstrates its strengths when used in applications in aggressive environments, such as in the chemical or vulcanization industry. The same is true for systems in which robust cleaning methods are used. Typical applications include packaging food in thermoformed trays and measuring the fill level in receiving tanks, as well as applications in car tyre production or processes in electroplating and painting systems, e.g., to detect parts moving into and out of an acid bath.
