Barometric Pressure, Temperature, and Humidity Module:
With these Orion weather stations, barometric pressure, temperature, and humidity measurements are combined in an advanced sensor module utilizing capacitive measurement method for each parameter.
Barometric pressure is measured using a silicon-based sensor. The sensor has minimal hysteresis and excellent repeatability, as well as outstanding temperature and long-term stability. The measurement range is from 17.72 to 32.48 in. Hg (600 to 1100 millibars)
Temperature measurement is based on a ceramic sensor. The measurement range is from -61.6 to 140 °F (-52 to +60 °C).
Humidity measurement is based on a capacitive technology. The sensor is highly accurate and it offers excellent long-term stability in a wide range of environments withnegligible hysteresis. The measurement range for humidity is 0 to 100% RH.
This tri-sensor module is mounted in a specially designed radiation shield and is easily replaceable and available as a spare component.
The shield protects the sensors form both scattered and direct solar radiation and precipitation. The plastic material in the plates offers excellent thermal characteristics and UV stabilized construction. The white outer surface reflects radiation, while the black inside absorbs accumulated heat.
