Meteorology

The CR800 series is used in long-term climatological

monitoring, meteorological research, and routine

weather measurement applications.

Sensors the CR800 series can measure include:

• cup, propeller, and sonic anemometers

• tipping bucket rain gauges

• wind vanes

• pyranometers

• ultrasonic ranging sensor

• thermistors, RTDs and thermocouples

• barometric pressure sensors

• RH sensors

Data is output in a choice of units (e.g., wind speed

in miles per hour, meters per second, or knots).

Standard outputs include wind vector averaging,

sigma, theta, and histograms.

Agriculture and Agricultural Research

The versatility of the CR800 and CR850 allows measure-

ment of agricultural 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. The reliability of these systems ensures

data collection, even under adverse conditions. Wide

operating temperature ranges and weatherproof

enclosures allow our systems to operate reliably in

harsh environments.

The CR800 or CR850 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 CR800

series monitors electrical current, voltage, wattage,

stress, and torque.

Applications

The measurement precision, exibility, long-term reliability, and economical price of the CR800 and CR850 make them

ideal for scientic, commercial, and industrial applications.
