SoilVUE 10 TDR Soil Moisture Profile Sensor

产品规格
Features

Accurate TDR-based soil water content, electrical conductivity, and temperature measurements from multiple depths.

 


Benefits and Features

l  Measures VWC, permittivity, EC, and temperature at six depths over 0.5 m or nine depths over 1.0 m using one sensor

l  Quick and low-impact installation

l  SDI-12 version 1.4 digital output that is compatible with most Campbell Scientific data loggers

l  Designed for long-term outdoor operation

 

Specifications

Measurements Made

Volumetric water content, permittivity, electrical conductivity, and temperature

Maximum Installation Torque

54 N m (40 ftlb)

Operating Voltage Range

9 to 36 Vdc

Diameter

5.2 cm (2.05 in.) without threads

5.8 cm (2.3 in.) including threads

1.9 kg/3.6 kg (4.2 lb/7.9 lb) depending on the option ordered

 

Current Drain

Active

~64 mA (@ 12 Vdc)

Quiescent

~1.5 mA (@ 12 Vdc)

 

Measurement Depths

0.5 m Option

5, 10, 20, 30, 40, and 50 cm (2, 4, 8, 12, 16, and 20 in.)

1 m Option

5, 10, 20, 30, 40, 50, 60, 75, and 100 cm (2, 4, 8, 12, 16, 20, 24, 30, and 40 in.)

 

Electrical Conductivity

Range

0 to 10 dS/m

Accuracy

±2% (0 to 2.5 dS/m)

±5% (full range)

 

Relative Dielectric Permittivity

Range

1 to 80

Accuracy

±1 permittivity unit (between 4 and 42 permittivity)

 

Volumetric Water Content

Water Content Accuracy

±1.5% typical with most soils 

Soils with high organic matter (> 12% soil organic carbon) or high clay content (> 45% clay) may need a soil-specific calibration due to the dispersive nature of these materials.

 

Soil Temperature

Accuracy

± 0.15°C (between -30° and +40°C)
