Benefits
- all domestic component and material base
- wide range of humidity and temperature measurement
- resistance to salt fog, rocket fuel components, increased chemical resistance
- IP66
- delivery with the military representation acceptance
Scope
Sensors are used in the configuration of various meteorological condition monitoring systems:
- road and ship weather stations
- compartments of inhabited and uninhabited vehicles
- automated airfield weather stations
Principle of Operation
The sensor is based on a sorption-capacitive sensing element manufactured by JSC Radar mms. The signal from the sensor element is converted into a digital code and transmitted via the RS-485 interface to secondary devices.
It ensures the capability to output analog signals.
