Overview

  • Opposed mode pair uses a 1450 nm sensing beam for accurate water detection in challenging applications
  • Offers high excess gain to burn through colored or decorated bottles and many plastic containers to detect the liquid contents inside
  • Features 13 mm diameter beam with a choice of 2, 4, or 8 m sensing range
  • Comes standard with three apertures to narrow sensing beam and reduce excess gain when needed to detect thin layers of water or small containers
  • Encapsulated electronics for reliable operation in food and beverage markets; rated for 1200 psi washdown
  • Excellent crosstalk avoidance allows 2 sensor pairs to be used in close proximity as a level switch
