Applications
The measurement precision, exibility, long-term reliability, and economical price of the CR1000 make it ideal for scienti c, commercial,
and industrial applications.
Meteorology
e CR1000 is used in long-term climatological moni-
toring, meteorological research, and routine weather
measurement applications.
Sensors the CR1000 can measure include:
Agriculture and Agricultural Research
e versatility of the CR1000 allows measurement
of agricultural processes and equipment in applica-
tions 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 Pro ling
Our data acquisition systems can monitor conditions
at wind assessment sites, at producing wind farms,
and along transmission lines. e CR1000 makes and
records measurements, controls electrical devices, and
can function as PLCs or RTUs. Because the datalog-
ger has its own power supply (batteries, 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
• barometric pressure
• wetness
• solar radiation
For turbine performance applications, the CR1000
monitors electrical current, voltage, wattage, stress,
and torque.
Soil Moisture
e CR1000 is compatible with the following soil
moisture 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 Re ectometry Systems (TDR) use a
re ectometer controlled by a CR1000 to accurately
measure soil water content. Multiplexers allow
sequential measurement of a large number of probes
by one re ectometer, reducing cost per measurement.
• Self-contained water content re ectometers are
sensors that emit and measure a TDR pulse.
• Tensiometers measure the soil pore pressure of
irrigated soils and calculate soil moisture.

National Park, MT.

sonic anemometers

and thermocouples
• barometric pressure
sensors
• RH sensors
• cooled mirror
