Campbell Scientific NR01 Sensor Specification

The Campbell Scientific NR01 is a high-precision net radiometer designed for comprehensive solar and atmospheric radiation measurement. It captures both shortwave and longwave radiation using four separate sensor components. The NR01 features two pyranometers for measuring incoming and reflected solar radiation, and two pyrgeometers for detecting longwave radiation emitted by the sky and the ground. This configuration allows it to accurately assess net radiation, a critical parameter in energy balance studies.

The instrument is constructed with a robust aluminum body and a glass dome that shields the sensors, ensuring durability and reliable performance in various environmental conditions. Its spectral range covers from 285 nm to 100,000 nm, accommodating broad-spectrum measurement needs. The NR01 operates efficiently within a temperature range of -40°C to +80°C, making it suitable for diverse climatic conditions.

Output is provided via a millivolt signal, which facilitates easy integration with data loggers. The NR01 includes a built-in temperature sensor to compensate for temperature-induced measurement errors, enhancing accuracy. It requires a power supply of 5 to 15 VDC, and its heating function minimizes condensation and frost on the domes, ensuring continuous data collection.

With a sensitivity of approximately 10 to 15 µV/W/m², the NR01 delivers precise readings necessary for meteorological, climatological, and agricultural research applications. Its design complies with ISO 9060:2018 standards for Class A instruments, which confirms its high quality and reliability for scientific research. The NR01 is an essential tool for researchers and professionals seeking detailed and accurate radiation data for various analytical and practical applications.

Campbell Scientific NR01 Sensor F.A.Q.

What are the recommended maintenance practices for the Campbell Scientific NR01 sensor?

Regularly clean the domes and windows using a soft cloth and mild soap solution to remove dust and debris. Check and tighten any loose connections and inspect the sensor cable for damage. Calibrate the sensor annually to ensure accurate measurements.

How can I troubleshoot if the NR01 sensor is not providing any data?

Check the power supply to ensure the sensor is receiving power. Verify all cable connections are secure. Use a multimeter to check for continuity in the cables. If the problem persists, contact Campbell Scientific support for further assistance.

How do I install the NR01 sensor for optimal performance?

Mount the NR01 sensor on a stable structure away from any obstructions that could cast shadows or reflect sunlight. Ensure the sensor is level and aligned properly using the built-in bubble level. Securely fasten the sensor to prevent movement or vibration.

What is the procedure for calibrating the NR01 sensor?

Calibration involves comparing the sensor's readings to a reference pyranometer under stable weather conditions. Adjust the sensor's output using the calibration factors provided by Campbell Scientific. It is recommended to have the calibration performed by trained personnel or a certified laboratory.

Can the NR01 sensor be used in extreme weather conditions?

Yes, the NR01 is designed to operate in a wide range of environmental conditions. It has a robust construction that can withstand temperatures from -40°C to 80°C and is weatherproof. However, regular maintenance is important to ensure longevity and accuracy.

How do I interpret the data output from the NR01 sensor?

The NR01 sensor outputs data in terms of net radiation, which is the balance of all incoming and outgoing radiation. The data is typically presented in watts per square meter (W/m²). Refer to the user manual for detailed explanation on data interpretation.

What are the common issues affecting data accuracy in NR01 sensors?

Common issues include dirty domes, incorrect leveling, nearby obstructions, and cable faults. Regular maintenance and proper installation are crucial to minimize these issues. Ensure the sensor is calibrated as recommended.

Is it possible to integrate the NR01 sensor with other data logging systems?

Yes, the NR01 can be integrated with various data logging systems. It provides analog voltage outputs that can be connected to compatible data loggers. Ensure that the data logger supports the voltage range and data format of the NR01.

What safety precautions should be taken during the installation of the NR01 sensor?

Ensure the installation is conducted on stable structures to prevent falls. Use appropriate personal protective equipment, such as gloves and helmets. Follow all electrical safety guidelines when making power connections.

How do I connect the NR01 sensor to a Campbell Scientific data logger?

Connect the sensor's output cables to the appropriate input channels on the data logger. Configure the data logger software to recognize the NR01 and set the data collection parameters according to the sensor's specifications. Refer to the data logger's manual for detailed instructions.
