SoilVue 10 TDR Soil Moisture and Temperature Profile Sensor

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. The threaded design with individual sensors built into the threads improves sensor contact with the soil to reduce potential error from air gaps. 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. 

The included cable has an IP67 rated M12 connector that is detachable from the sensor for easy field replacement if the cable becomes damaged.
