Overview

The SoilVue 10 uses time‑domain reflectometry (TDR) to measure soil volumetric water content (VWC) and electrical conductivity (EC). The waveguides (measurement rods) are embedded in threads and centered on the measurement depths of 5, 10, 20, 30, 40, and 50 cm for the 0.5 m option ( SoilVue 10 waveguides and measurement depths); depths of 60, 75, and 100 cm are added for the 1.0 m option. The threaded design maximizes soil contact and minimizes preferential flow—two major drawbacks to smooth‑sided soil profiling probes. This proprietary implementation of TDR by Campbell Scientific produces a clean, high resolution measurement that provides accuracy and assurance that cannot be found among other commercially available sensors.

SoilVue 10 waveguides and measurement depths

The SoilVue 10 should be installed in a hole made by a standard 5‑cm (2‑in) hand auger tool. Auger the hole to the proper depth and screw the SoilVue 10 into the hole (see Field installation). Water should be used to lubricate the sides of the hole to aid in installation and to ensure the probe is not damaged due to excessive force. The threaded design presses the sensing elements into the side of the hole, producing optimal contact with the soil and minimizing air gaps that are common with alternative profile probes.

The SoilVue 10 also has a detachable cable that allows either the probe or cable to be independently replaced if it gets damaged.

All of these design factors combine to result in a more accurate measurement.

Features:

  • Volumetric water content (VWC), electrical conductivity (EC), permittivity, and temperature measurements at six depths over 0.5 m or nine depths over 1.0 m using one probe

  • Campbell Scientific proprietary TrueWave™ TDR technology uses advanced waveform analysis to determine the true travel time of a high frequency pulse that provides defensible measurements that can be universally compared with other TDR systems

  • Threaded design with individual waveguides built into the threads for optimal contact with soil, which minimizes air‑gap errors

  • Installation using a standard 5‑cm (2‑in) hand auger, thus eliminating the need for excavation machinery or expensive proprietary tools

  • Quick, low-impact installation

  • Detachable cable that facilitates field replacement

  • SDI‑12 digital output

  • Designed for long‑term outdoor operation

  • Compatible with the Aspen 10 Edge Device.

  • Compatible CRBasic data loggers: GRANITE-series, CR6, CR1000X, CR800-series, CR350-series, CR300-series, CR3000, CR1000
