Precipitation sensor IRSS88T
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
