Ultrasonic sensors are widely used in industrial applications due to their non-contact nature and accuracy. However, they often face challenges when exposed to aggressive substances such as vapors or harsh cleaning agents. These chemicals can degrade the sensor’s transducer (the part of the sensor that emits ultrasonic waves), leading to impaired performance.

The new UNAR/URAR 12 miniature sensors from Baumer address this issue with a groundbreaking patented parylene coating on their sensor face and an all-metal stainless steel housing. This combination makes them exceptionally resistant to chemical attacks, ideal for demanding environments where corrosive substances are present.

Key Features

  • Patented Parylene Coating: The ultra-thin parylene layer provides excellent protection against chemicals without adding bulk or affecting the sensor’s functionality.
  • Stainless Steel Housing: This all-metal construction ensures durability and resistance to wear, even in aggressive settings.
  • Compact Design: These sensors seamlessly integrate into existing Baumer portfolios, available as proximity, retro-reflective, and distance sensors.

Ideal Applications

The UNAR/URAR 12 sensors are versatile tools suitable for a wide range of industries:

Industrial Use Cases

  • Printing Industry: Measuring levels in paints and varnishes
  • Pharmaceutical Sector: Monitoring compact laboratory containers or pressure tanks
  • Food & Beverage: Fast detection of bottles in filling processes, enabled by their <6ms response time and narrow sound beam.

These sensors comply with FDA standards for material safety, making them suitable for hygienic environments where food processing is involved.

Installation Advantages

Unlike traditional ultrasonic sensors that require additional mounting aids due to metal caps, the parylene-coated UNAR/URAR 12 models can be installed effortlessly without extra tools or accessories. This simplifies integration into existing systems and reduces installation time.
