System SP
Product details
Our large detector kit is best suited for agricultural installations for long-term monitoring of soil moisture. It provides the best time resolution, specifically for challenging environments or irrigation management.
- Cosmic-Ray Neutron Sensing Probes
- Larger-sized detector
- Hourly averages
- Typical count rate per hour: 2300. Upgradable to up to 5000 cph.
- Starting from 9200.00 €
Equipment
- Battery, PV panel and charger.
- GPS receiver: Position and time measurement (horizontal precision: 2.5 m, maximum update rate: 1 Hz).
- Thermal neutron shielding (Nibranium) based on a gadolinium coating.
Environment Sensors:
- Air pressure (Resolution: 0.2 Pa, Precision: 1.7 hPa)
- temperature (Resolution: 0.01 K, Precision: 1 K)
- humidity (Resolution: 0.008%, Precision: 3%).
Below some exemplary configurations are shown:
The CRNS detector is usually mounted 1 to 2 meters above the ground surface, providing a significant exposure to far-field radiation from albedo neutrons which have further penetrated tens of decimeters through the soil. The neutron count rate is representative of the average root-zone water content in a footprint of up to 18 hectares and 20 cm to 70 cm in depth.
