Overview
The SoilVUE™10 is a soil water content profile sensor powered by Campbell TrueWave™TDR technology. This soil moisture, electrical conductivity, and temperature profile sensor was developed with environmental researchers and environmental monitoring networks in mind. The SoilVUE™10 represents several exciting advancements in in-situ soil measurement that should make this an extremely compelling option for anyone in these applications who needs to make multiple measurements in a profile.
Campbell Scientific’s proprietary TrueWave™TDR technology combines a best-in-class rise time with an advanced waveform analysis technique to determine the true travel time of a high-frequency pulse. This process achieves a high-resolution, smooth signal for measurements that are defensible and can be universally compared with other TDR measurements. Not all TDR-based sensors perform equally well.

Detailed Description
The SoilVUE™10 consists of TDR circuitry connected to a series of six or nine helical wave guides that make up part of the overall threaded design.内置螺纹内置的单个传感器的螺纹设计可提高传感器接触土壤，以减少空气间隙的潜在误差。The TDR circuitry generates a short rise time electromagnetic pulse that is applied to the helical wave guides. The elapsed two-way travel time of the applied pulse is used to calculate the dielectric permittivity of the surrounding media and determine the volumetric water content using a mixing model.
The soil water content profile sensor can be installed in a hole made by a standard 5 cm (2 in.) hand auger. Excavation machinery or expensive custom tools are not necessary to install the sensor.
附带的电缆具有IP67额定M12连接器，如果电缆损坏，则可从传感器上拆卸。
