Campbell Scientific CMP6 Pyranometer Specification

The Campbell Scientific CMP6 Pyranometer is a precision instrument designed for meteorological and solar energy applications to measure global solar radiation. This pyranometer features a thermopile sensor which is sensitive to a broad spectrum of solar radiation ranging from 285 to 2800 nanometers, ensuring accurate measurement of both direct and diffuse solar irradiance. The device is constructed with a robust, weather-resistant housing, making it suitable for long-term outdoor installations in various environmental conditions.

The CMP6 employs a glass dome to shield the sensor from environmental influences such as wind and precipitation, enhancing the accuracy and stability of measurements. It has a high-quality blackened thermopile surface that absorbs solar energy and converts it into an electrical signal, which is then amplified to provide an output voltage proportional to the solar radiation intensity. Calibration of the CMP6 complies with the ISO 9847 standard, ensuring reliable performance and consistent data output.

With a sensitivity of approximately 5 to 20 microvolts per watt per square meter, the CMP6 pyranometer offers a measurement range capable of capturing radiation levels from low light conditions to full sunlight. The device operates effectively within a temperature range of -40°C to +80°C, ensuring versatility across diverse climatic conditions. The pyranometer is compatible with Campbell Scientific data loggers and is often integrated into weather stations for comprehensive environmental monitoring. Its design emphasizes ease of installation, maintenance, and integration, making the CMP6 a preferred choice for researchers and professionals in the fields of meteorology, climatology, and solar energy assessment.

Campbell Scientific CMP6 Pyranometer F.A.Q.

How do I install the Campbell Scientific CMP6 Pyranometer?

To install the CMP6 Pyranometer, mount it on a stable, level surface using the mounting rod provided. Ensure the sensor is unobstructed from the sun and oriented properly according to the manufacturer's instructions. Connect the sensor cable to a compatible data logger for data acquisition.

What maintenance is required for the CMP6 Pyranometer?

Regular maintenance includes cleaning the sensor's dome with a soft, lint-free cloth and distilled water to remove dust and debris. Inspect the cable and connections periodically for damage or corrosion. Calibration should be verified annually.

How can I troubleshoot if the CMP6 Pyranometer is not providing data?

Check the connections between the pyranometer and the data logger. Ensure that the cable is intact and properly connected. Verify that the data logger is configured correctly to receive data from the CMP6. If the issue persists, consult the user manual for further diagnostics or contact technical support.

What is the operating temperature range for the CMP6 Pyranometer?

The CMP6 Pyranometer operates effectively within a temperature range of -40°C to 80°C (-40°F to 176°F). Ensure the installation location does not exceed these temperature limits.

How do I calibrate the CMP6 Pyranometer?

Calibration of the CMP6 Pyranometer should be done by comparing it with a reference sensor under stable and clear sky conditions. Follow the manual's instructions for calibration procedures or send it to an authorized service center for professional calibration.

Can the CMP6 Pyranometer be used in a network of sensors?

Yes, the CMP6 can be integrated into a network of sensors through a compatible data logger that supports multiple inputs. Use appropriate software to configure and manage the network for synchronized data collection.

What should I do if the pyranometer's readings are inconsistent?

Ensure that the sensor is clean and unobstructed. Verify proper leveling and orientation. Check all electrical connections for security and integrity. If inconsistencies persist, recalibrate the sensor and consult technical support if necessary.

Is it necessary to level the CMP6 Pyranometer?

Yes, it is crucial to level the CMP6 Pyranometer for accurate readings. Use the built-in bubble level and adjust the mounting until the sensor is perfectly level.

How can I protect the CMP6 Pyranometer from environmental damage?

Install the pyranometer in a location that minimizes exposure to harsh weather conditions. Use protective enclosures or shields if necessary, but ensure they do not obstruct the sensor's view of the sky. Regular maintenance will also help protect against environmental damage.

What data logger is compatible with the CMP6 Pyranometer?

The CMP6 Pyranometer is compatible with a variety of Campbell Scientific data loggers, such as the CR1000X, CR300, and CR6. Ensure the data logger supports the sensor's output and configure it according to the manufacturer's guidelines.
