Ultrasonic miniature sensors with patented coating for level measurement
Aggressive media such as vapors or cleaning agents are at times a challenge for standard ultrasonic sensors. The sensor face called a transducer, can be worn by these media and thus become impaired. The new chemically robust UNAR / URAR 12 miniature sensors are a great fit for these environments thanks to an ultra-thin patented perylene coating on the sensor face and stainless steel all-metal housing. These compact sensors are an addition to the preexisting Baumer portfolio of chemically robust sensors and are available as proximity, retro-reflective, and distance sensors.
