World's smallest ultrasonic sensor
At 18mm in diameter and 55mm in length the UMB800 from Pepperl+Fuchs is claimed to be the world's smallest ultrasonic sensor in solid stainless steel. With its large detection range and highly compact design, it opens up new automation possibilities in hygienic applications.
The 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, minimising the risk of microbial contamination. The outer skin is hermetically sealed and free from gaps. The sensor is said to withstand steam jet treatment and aggressive cleaning agents.
Although small, the sensor is claimed to provide a wide measuring range from a dead band of 70mm and a detection range of 800mm. The sensor is resistant to significant temperature fluctuations and remains functional at a continuous operating temperature of up to 85°C.
The UMB800 series demonstrates its strengths when used in applications in aggressive environments, such as in the chemical or vulcanisation 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.
