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 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 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 in-
clude, 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. Multi-
plexers 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.
