Campbell Scientific LI200X-L Sensor Specification

The Campbell Scientific LI200X-L Sensor is a precision instrument designed for accurate measurement of solar radiation. It is primarily used in meteorological and climatological applications, where reliable solar data is crucial. This pyranometer is engineered to measure global solar radiation in the range of 400 to 1100 nanometers, which encompasses the spectrum of sunlight most relevant to terrestrial solar energy assessments. The LI200X-L utilizes a photodiode sensor, which is carefully calibrated to provide a high level of accuracy and stability, ensuring that it delivers consistent performance even under harsh environmental conditions.

The sensor features a robust and weather-resistant design, making it suitable for long-term outdoor deployment. It is housed in a durable anodized aluminum body with a dome-shaped optical diffuser that ensures uniform sensitivity to sunlight from all angles, thus minimizing errors due to the angle of incidence. The LI200X-L is designed to operate in a wide temperature range, offering reliable performance from -40 to 65 degrees Celsius, which makes it suitable for various climates and geographical locations.

Data from the sensor is transmitted through a shielded cable, which is available in user-specified lengths, ensuring flexibility in installation. Its compatibility with Campbell Scientific data loggers and other data acquisition systems allows for seamless integration into existing monitoring networks. The LI200X-L is factory-calibrated against a secondary standard pyranometer, providing traceability to international standards. This ensures that the data it collects is both accurate and reliable, making the LI200X-L an excellent choice for researchers and professionals who require precise solar radiation measurements.
