Meteorology
The CR1000 is used in long-term climatological monitor-
ing, meteorological research, and routine weather mea-
surement applications.
Sensors the CR1000 can measure include:
Data is output in your choice of units (e.g., wind
speed in miles per hour, meters per second, or knots).
Standard CR1000 outputs include wind vector averag-
ing, sigma, theta, histograms, saturation vapor pressure,
and vapor pressure from wet/dry bulb temperatures.
Agriculture and Agricultural Research
The versatility of the CR1000
allows measurement of agricul-
tural processes and equipment
in applications such as:
• plant water research
• canopy energy balance
• machinery performance
• plant pathology
• crop management decisions
• food processing/storage
• frost prediction
• irrigation scheduling
• integrated pest management
Wind Profiling
Our data acquisition systems can monitor conditions at
wind assessment sites, at producing wind farms, and
along transmission lines. The reliability of these sys-
tems ensures data collection, even under adverse condi-
tions. Wide operating temperature ranges and weather-
proof enclosures allow our systems to operate reliably
in harsh environments.
The CR1000 makes and records measurements, controls
electrical devices, and can function as PLCs or RTUs.
Because the datalogger has its own power supply (bat-
teries, solar panels), it can continue to measure and
store data and perform control during power outages.
Typical sensors for wind assessment applications
include, but are not limited to:
• sonic anemometers
• three-cup and propeller
anemometers (up to
10 anemometers can be
measured by using two
LLAC4 peripherals)
• wind vanes
• temperature sensors (air,
water, and equipment)
• barometric pressure
• wetness
• solar radiation
For turbine performance applications, the CR1000 can mon-
itor electrical current, voltage, wattage, stress, and torque.
Soil Moisture
The CR1000 is compatible with the following soil mois-
ture measurement technologies:
• Soil moisture blocks are inexpensive sensors that
estimate soil water potential.
• Matric water potential sensors also estimate soil
water potential but are more durable than soil
moisture blocks.
• Time-Domain Reflectometry Systems (TDR) use a
reflectometer controlled by a CR1000 to accurately
measure soil water content. Multiplexers allow sequen-
tial measurement of a large number of probes by
one reflectometer, reducing cost per measurement.
• Self-contained water content reflectometers are
sensors that emit and measure a TDR pulse.
• Tensiometers measure the soil pore pressure of
irrigated soils and calculate soil moisture.
Applications
The measurement precision, flexibility, long-term reliability, and economical price of the CR1000 make it ideal for
scientific, commercial, and industrial applications.
