Precipitation sensor IRSS88T

Print

The precipitation sensor IRSS88T includes an additional integrated temperature measurement and a serial interface (RS232). The IRSS88T has a separate temperature sensor in an aluminum mounting on its core housing. This makes it possible to measure the ambient temperature accurately to 0.1 ° C and to control a potential-free switching output via a switching hysteresis function. The hysteresis can be adjusted between 0 ° C and 9 ° C by means of two rotary selector switches.

Special features include:

  • Insensitive to interfering light
  • Connecting cable up to 1000 m possible
  • Low power consumption
  • Stainless steel housing, brown coated
  • Fast reaction time
  • Extremely robust

 

The IRSS88T precipitation sensor is used in particular in the following areas:

  • Traffic control systems
  • Treatment plants
  • Facility management
  • Research vessels in the polar circle
