Campbell Scientific LI200X-LC Sensor F.A.Q.

What is the primary application of the Campbell Scientific LI200X-LC Sensor?

The Campbell Scientific LI200X-LC Sensor is primarily used for measuring solar radiation in meteorological and agricultural applications. It provides accurate readings of sunlight intensity, which is crucial for research and monitoring purposes.

How do I calibrate the LI200X-LC Sensor?

The LI200X-LC Sensor is factory-calibrated, but if recalibration is needed, it should be done by comparing it to a reference sensor under natural sunlight conditions. Calibration adjustments can be made using a data logger that processes the sensor's output.

What maintenance is required for the LI200X-LC Sensor to ensure accurate readings?

Regular maintenance includes cleaning the sensor's surface to remove dust and debris, checking the level to ensure proper orientation, and inspecting cables and connections for wear or damage.

How can I troubleshoot inconsistent readings from my LI200X-LC Sensor?

Begin troubleshooting by checking the sensor's physical condition for dirt or damage. Verify the connections and wiring for faults. Cross-check the readings with another sensor if possible, and ensure proper calibration settings are applied in your data logger.

What is the optimal installation height for the LI200X-LC Sensor?

The optimal installation height for the LI200X-LC Sensor depends on the application, but it should be placed in an unobstructed area where it can receive direct sunlight. Typically, it’s mounted on a tripod or a mast at a standard height that prevents shadows from surrounding objects.

Can the LI200X-LC Sensor be used in extreme weather conditions?

Yes, the LI200X-LC Sensor is designed to operate in a wide range of environmental conditions, including extreme weather. However, it is essential to ensure that the sensor is securely mounted and protected against physical damage from severe weather events.

How do I integrate the LI200X-LC Sensor with my data logging system?

Integration involves connecting the sensor's output to a compatible data logger and configuring the logger to recognize and record the sensor's measurements. Refer to your data logger’s manual for specific wiring and configuration instructions.

What output does the LI200X-LC Sensor provide, and how do I interpret it?

The LI200X-LC Sensor provides an analog voltage output that is proportional to the solar radiation intensity. This output can be converted to a radiation value using the calibration factor provided by the manufacturer, typically measured in watts per square meter (W/m²).

Is it necessary to shield the LI200X-LC Sensor from rain or snow?

The LI200X-LC Sensor is weather-resistant and does not require shielding from rain or snow. However, accumulating snow or ice should be removed from the sensor's surface to ensure accurate readings.

What should I do if the LI200X-LC Sensor cable gets damaged?

If the cable is damaged, it should be replaced or repaired by a qualified technician to prevent inaccurate readings or further damage. Ensure that any repairs maintain the integrity of the waterproof seal to avoid moisture ingress.
