Applications
e measurement precision, exibility, long-term reliability, and economical price of the CR1000 make it ideal for scientic, commercial, and industrial applications.
Meteorology
The CR1000 is used in long-term climatological monitoring, meteo-
rological research, and routine weather measurement applications.
Sensors the CR1000 can measure include:
Agriculture and Agricultural Research
The versatility of the CR1000 allows measurement of agricultural
processes and equipment in applications such as:
Wind Proling
Our data acquisition systems can monitor conditions at wind assess-
ment sites, at producing wind farms, and along transmission lines. The
CR1000 makes and records measurements, controls electrical devices,
and can function as PLCs or RTUs. Because the datalogger 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:
cup, propeller, and sonic anemometers (up to 10 anemometers
can be measured by using two LLAC4 peripherals)
wind vanes
thermistors, RTDs, and thermocouples
barometers
pyranometers
For turbine performance applications, the CR1000 monitors electrical
current, voltage, wattage, stress, and torque.
Soil Moisture
The CR1000 are compatible with the following soil moisture mea-
surement 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 Reectometry Systems (TDR) use a reectom-
eter controlled by the datalogger to accurately measure soil water
content. Multiplexers allow sequential measurement of a large
number of probes by one reectometer.
Self-contained water content reectometers are sensors that
emit and measure a TDR pulse.
Tensiometers measure the soil pore pressure of irrigated soils
and calculate soil moisture.
