Campbell Scientific SR05 Sensor Specification

The Campbell Scientific SR05 Sensor is a high-performance pyranometer designed for accurate measurement of solar irradiance. It operates within a spectral range of 285 to 3000 nanometers, capturing both direct and diffuse solar radiation. The sensor is built to adhere to ISO 9060:2018 standards, classified as a Class C pyranometer, ensuring reliable and precise data collection for a variety of meteorological and solar energy applications.

The SR05 boasts a thermopile sensor technology that provides a flat spectral response, minimizing errors associated with varying solar angles and environmental conditions. Its robust construction features a blackened thermopile protected by a high-quality glass dome, which enhances durability and performance by shielding the sensor from environmental contaminants and moisture. The SR05 operates efficiently across a wide temperature range from -40°C to +80°C, making it suitable for diverse climatic conditions.

The sensor includes a built-in bubble level and adjustable leveling screws, facilitating easy installation and precise alignment on site. It outputs a millivolt signal proportional to the solar radiation received, which can be easily integrated with Campbell Scientific dataloggers or other data acquisition systems for seamless data processing and analysis. The SR05 is equipped with a 5-meter cable, with options for longer lengths to accommodate various installation needs.

Overall, the Campbell Scientific SR05 Sensor is a reliable, cost-effective solution for measuring solar radiation, ideal for researchers, solar energy professionals, and meteorologists seeking dependable data for analysis and decision-making.

Campbell Scientific SR05 Sensor F.A.Q.

How do I install the Campbell Scientific SR05 sensor?

To install the SR05 sensor, mount it on a stable, level platform using the provided mounting hardware. Ensure the sensor is oriented correctly with the cable pointing downward to prevent water ingress. Connect the sensor to a compatible data logger using the appropriate wiring configuration.

What maintenance is required for the SR05 sensor?

Regularly clean the sensor's glass dome with a soft, lint-free cloth and a mild cleaning solution. Check the sensor's cable and connection for any signs of wear or damage. Perform a calibration check annually to ensure accuracy.

How can I troubleshoot connectivity issues with the SR05 sensor?

First, verify that the sensor is properly connected to the data logger. Check for any loose or damaged cables. Use a multimeter to test the continuity of the wires and ensure proper voltage levels. Consult the data logger's manual for further troubleshooting steps.

What is the correct way to wire the SR05 sensor to a data logger?

Refer to the sensor's manual for the wiring diagram. Typically, the SR05 has a ground wire, a power supply wire, and an output signal wire. Connect each wire to the corresponding terminal on the data logger, ensuring secure and correct connections.

How do I perform a calibration check on the SR05 sensor?

Compare the sensor's output with a reference pyranometer under the same conditions. If discrepancies are noted, adjust the calibration factor in the data logger settings. It's recommended to perform this check annually or whenever the sensor is suspected of drifting.

What should I do if the SR05 sensor gives erratic readings?

Check for and remove any obstructions or dirt on the sensor's glass dome. Verify that the sensor is level and properly mounted. Ensure the cable connection is secure and undamaged. If the problem persists, consult technical support for further assistance.

Can the SR05 sensor be used in extreme weather conditions?

Yes, the SR05 is designed to operate in a wide range of environmental conditions, but it is important to ensure it is mounted securely to withstand high winds and that the cable is protected from ice and snow build-up.

How do I interpret the data output from the SR05 sensor?

The SR05 outputs a voltage signal proportional to solar irradiance. This signal can be converted to W/m² using the calibration factor provided with the sensor. The data logger should be configured to apply this conversion automatically.

What are the common causes of data drift in the SR05 sensor?

Data drift can be caused by dirt or dew on the sensor dome, electrical interference, or physical damage. Regular maintenance and calibration checks can help mitigate these issues.

Is the SR05 sensor compatible with all Campbell Scientific data loggers?

The SR05 is compatible with most Campbell Scientific data loggers, but it is essential to check the data logger's specifications for voltage input range and compatibility with the sensor's output signal.
