Campbell Scientific LP02 Sensor Specification

The Campbell Scientific LP02 is a high-precision pyranometer designed for accurate measurement of solar radiation. It is commonly used in meteorological, climatological, and solar energy applications to monitor solar irradiance. The LP02 features a thermopile sensor that measures the solar energy received on a plane surface in watts per square meter. This pyranometer is compliant with ISO 9060:2018, classified as a Second Class pyranometer, ensuring reliable performance for standard solar radiation measurements.

The LP02 is equipped with a blackened thermopile protected by a glass dome, which aids in reducing long-wave radiation losses and provides a wide spectral range from 285 nm to 3000 nm. Its robust construction makes it suitable for various environmental conditions, featuring an anodized aluminum body and a durable cable for long-term outdoor use. The sensor operates efficiently within a temperature range of -40°C to 80°C, allowing for versatile deployment in diverse climates.

The LP02 requires no power supply as it generates a millivolt output, which can be measured by compatible data loggers or voltmeters. It has a sensitivity range typically between 10 to 35 µV/W/m², enabling precise data capture essential for solar resource assessment and research. The combination of its compact size, ease of installation, and low maintenance requirements makes the Campbell Scientific LP02 a practical solution for both standalone and integrated measurement systems. With its proven reliability and accuracy, it is an ideal choice for professionals seeking to enhance their solar radiation monitoring capabilities.

Campbell Scientific LP02 Sensor F.A.Q.

How do I install the Campbell Scientific LP02 sensor for optimal performance?

To install the LP02 sensor, ensure it is mounted horizontally on a stable surface away from any obstructions that may cast shadows. Use the mounting rod and leveling base provided, and connect the sensor to a compatible data logger using the supplied cable.

What is the proper way to connect the LP02 sensor to a data logger?

The LP02 sensor should be connected to the data logger using the supplied cable. Follow the wiring diagram provided in the sensor's manual to connect the wires to the appropriate terminals on the data logger.

How can I calibrate the LP02 sensor?

The LP02 sensor is factory-calibrated, but you can perform a field calibration by comparing its readings against a reference pyranometer under similar conditions. Adjust the calibration factor in your data logger settings if necessary.

What maintenance is required for the LP02 sensor?

Regular maintenance includes cleaning the sensor dome with a soft cloth and mild detergent, checking the cable connections for corrosion, and ensuring the sensor is level. Perform these checks at least twice a year or more frequently in harsh environments.

How can I troubleshoot inconsistent readings from the LP02 sensor?

Check for obstructions casting shadows, ensure the sensor is level, verify all cable connections, and inspect the sensor surface for dirt or damage. If issues persist, consult the sensor's manual or contact technical support.

What environmental conditions can affect the LP02 sensor's accuracy?

Factors such as dirt on the sensor surface, shading from nearby objects, and extreme weather conditions can affect accuracy. Regular maintenance and proper installation can mitigate these effects.

Is the LP02 sensor compatible with all Campbell Scientific data loggers?

The LP02 sensor is compatible with most Campbell Scientific data loggers. Verify compatibility by checking the data logger's specifications and the sensor's manual for wiring instructions.

How do I interpret the data collected from the LP02 sensor?

The LP02 sensor measures solar radiation in watts per square meter. Use the data logger software to convert raw data into readable values and analyze trends over time.

What is the expected lifespan of the LP02 sensor?

The LP02 sensor is designed for long-term outdoor use and can last several years with proper maintenance. Environmental factors and handling can influence its lifespan.

Can the LP02 sensor be used in extreme weather conditions?

The LP02 sensor is built to withstand a wide range of weather conditions, but it should be protected from physical damage and regularly maintained to ensure accuracy and longevity.
