Orion Transmitter/Sensor Module
Parameter Measurements
Barometric Pressure, Temperature, and Humidity
are combined in a trisensor
module utilizing a capacitive measurement method for each parameter.
A radiation shield protects the sensors from both scattered and direct sunlight
and precipitation. The composite 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.
The internal sensor module is easily replaceable and available as a spare part.
Barometric pressure is measured using a silicon-based sensor. The temperature
sensor is ceramic. Relative humidity measurement is highly accurate with negligible
hysteresis and excellent long-term stability in a wide range of environments.
Wind Measurement
Wind speed and direction are measured using advanced ultra-sonic technology.
Three equally-spaced ultrasonic transducers on a horizontal plane ensure
accurate wind measurement from all directions, without blind angles or corrupted
readings.
Rainfall Measurement
Rainfall is measured with an impact sensor which detects the size and impact
of individual rain drops. The resulting signals are proportional to the volume of
the drops. Hence, the signal from each drop can be converted directly to the
accumulated rainfall.
This measurement method eliminates scattering, flooding and clogging, as well
as wetting and evaporation losses.
Additional Calculated Parameters
Data from these sensors are computed to provide calculated parameters
including Dew Point, Heat Index, Wind Chill, Degree-Day Temperatures and
Density Altitude.
System Configurations
All systems include the Orion Interface Module with dual communication ports
and the Orion Transmitter Module with the following sensors:
• Ultrasonic wind speed and direction sensor with alignment adapter
• Impact rainfall sensor
• Barometric pressure, temperature, humidity sensor module in radiation shield
