U2GT Full-Metal Ultrasonic Sensors in 316L Hygienic Design

With the U2GT series of ultrasonic sensors, the wenglor sensoric group has developed a new hygiene product range specifically for the requirements of the food, pharmaceutical and chemical industries. The ultrasonic sensors presented in the high-grade stainless steel 316L housing have been specially optimized for measurement and detection tasks in hygienically demanding applications, as well as in washdown applications. The product series comprises a total of four ultrasonic sensors.

Both the housing and membrane of the U2GT series sensors are made of stainless steel, which makes them particularly resistant to aggressive cleaning agents, the use of high-pressure cleaners and complete rinsing processes. 

Robust Housing for Certified Protection
Whether aggressive cleaning agents, harmful vapors from acids or direct contact with chemical media – the U2GT ultrasonic sensors are protected by their hermetically sealed stainless steel 316L housing (1.4404/V4A) and therefore have the highest protection classes IP68 and IP69K. This was made possible by numerous internal test series under extreme conditions as well as external certification procedures. All sensors in the series are also ECOLAB® certified, which means they are resistant to cleaning agents, and meet all requirements of the US FDA for the food industry. 

Hard Shell, High-Performance Core
In addition to their extraordinary robustness, the sensors from the U2GT series also have impressive performance characteristics. While the distance sensors can map working ranges of up to 1,300 mm in reflex mode, distances of up to 2,600 mm are possible in through-beam mode. The sensors are available with switching or analog output. The U2GT series can be configured either via the IO-Link interface or via external teach-in. These features come into their own in the food, beverage, pharmaceutical and chemical industries, in particular for checking for presence, positioning, and continuous container level measurement.
