Precipitation sensor IRSS88


The precipitation sensor IRSS88 is based on a photoelectric beam principle and has a detection area of approx. 120 x 25 mm which is sufficient to reliably detect even low precipitation densities with the smallest particle size. Its high-sensitivity microelectronics are insensitive to any kind of interfering light. The all-metal housing ensures effective shielding against RF exposure.

Special features include:

  • Insensitive to interfering light
  • Connecting cable up to 1000 m possible
  • Low power consumption
  • Stainless steel housing, optionally powdercoated
  • Fast reaction time


The precipitation sensor IRSS88 is used in particular in the following areas:

  • Traffic control systems
  • Treatment plants
  • Facility management
