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
with negligible 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.
