CR10X Measurement and Control System

Measurement Example — Weather Station

Measurements: The CR10X measures wind speed and direc-

tion, air temperature, relative humidity, precipitation, baro-

metric pressure, soil moisture and temperature, and solar radi-

ation. Scan rates are programmable from 1/64 second to 2.5

hours.

Data Processing: Output intervals for raw or processed data

are user-specified. Typically, hourly and daily summaries

(e.g., maxima, minima, averages, histograms) are stored.

Conditional outputs, such as rainfall intensity, can also be

processed and stored.

Data Storage: The non-volatile Flash memory and lithium-

backed SRAM store up to 62,000 data points—equating to

more than three months of data when typical hourly and daily

outputs are stored from typical meteorological application. An

optional memory expansion allows the CR10X to store more

than one million data points—or about 12 years’ worth of

meteorological data.

Data Retrieval: Data can be transferred to a computer using

telephones (including cellular or voice-synthesized), radio

telemetry, short-haul modems, satellite transmitters, mul-

tidrop modems, Ethernet, or storage modules.

12-Volt Power: The low-power design allows the CR10X to

operate up to one year on a 7 Ahr, unregulated 12 Vdc source,

depending on scan rate, number of sensors, data retrieval

method, and external temperature.

Measurement and Control Example — Head Gates

Measurements: The CR10X measures water level upstream,

downstream, and in a diversion ditch.

Data Storage/Processing/Retrieval: Data are recorded over

time, showing trends. The CR10X calculates flow and summa-

rizes the data as averages, maxima, or totals. A PC, Palm

handheld, or keyboard display can show both real-time and

summarized data.

Equipment Control: The CR10X controls multiple headgates

based on measured conditions, flow, or time. The control

capabilities of the CR10X allow levels to be maintained, even

in the absence of a manager. The gates can also be controlled

remotely by the water master if conditions change.

Alarms: If high or low water levels are detected, the CR10X

can initiate on-site alarms, data or voice-synthesized warning

calls, or activate pagers.

The CR10X is a rugged measurement and control system that delivers accurate, reliable measurements in a variety of applications.

Designed for both research and day-to-day monitoring operations, the CR10X combines the ability to measure virtually any sensor

with the control capability to respond to specific site conditions (e.g., open flood gates, turn fans off/on). From simple to complex,

Campbell Scientific data acquisition systems are at work on every continent, at sea, and in space.
