Campbell Scientific Q7.1 Sensor Specification

The Campbell Scientific Q7.1 Sensor is a precise instrument designed for measuring net radiation, the balance between incoming and outgoing radiation at a surface. This sensor is particularly suitable for applications in climatology, meteorology, and agricultural research, where understanding radiation dynamics is crucial. The Q7.1 features a thermopile sensor that measures the differential temperature created by absorbed radiation, providing a reliable analog signal proportional to the net radiation. It operates effectively within a spectral range of approximately 0.3 to 60 micrometers, covering both shortwave and longwave radiation. The sensor's rugged construction ensures durability in various environmental conditions, featuring a weather-resistant housing that protects the sensitive components from moisture and physical impact. It requires no external power source, making it convenient for remote deployments. Calibration is factory-set, guaranteeing accuracy and eliminating the need for frequent recalibrations. The sensor can be easily integrated into existing data acquisition systems via its standard cable connection, which is compatible with common data loggers. The Q7.1 is compact and lightweight, simplifying installation and maintenance in field conditions. Its operational temperature range extends from -40 to +70 degrees Celsius, ensuring reliable performance across diverse climates. This sensor is an invaluable tool for researchers and professionals seeking accurate and dependable radiation measurements to inform their studies or operational decisions.

Campbell Scientific Q7.1 Sensor F.A.Q.

How do I properly install the Campbell Scientific Q7.1 Sensor?

To properly install the Q7.1 Sensor, ensure it is mounted at an appropriate height above the surface to be measured, with the sensor's sensing element facing downwards. It should be located away from obstructions that might cast shadows or reflect sunlight.

What maintenance is required for the Q7.1 Sensor?

Regularly clean the sensor's surface using a soft cloth and mild detergent to ensure accurate readings. Inspect the cables and connections for any signs of wear or damage. Calibration should be checked annually.

How do I troubleshoot inconsistent readings from the Q7.1 Sensor?
