Soil moisture temperature conductivity sensor

SOLYX14Soil moisture temperature conductivity sensorIt is a maintenance free complex dielectric (CDX technology) sensor suitable for long-term, continuous in-situ measurement of volumetric water content (VWC), temperature, and electrical conductivity (EC). It can be installed in mineral soils, various types of cultivation media, and other porous materials. The VWC and EC values are determined through complex dielectric technology (CDX technology) using a frequency of 70MHz, which effectively reduces the influence of soil texture and salinity, enabling SOLYX14 to achieve accurate measurement in most soils. SOLYX14 has been carefully designed and rigorously tested for durability.

The Complex Dielecthrough Intersection (CDX) technology, developed by scientists from METER, is an impedance technique that covers a wide range of salinities and temperatures. By measuring complex dielectric constants,SOLYX14Soil moisture temperature conductivity sensorCapable of independently measuring both the real part dielectric constant (related to moisture content) and the imaginary part dielectric constant (the latter being affected by salt and lossy clay) simultaneously. This means that you can measure soil moisture in more locations more accurately than ever before.

PrincipleCDXTechnology)
CDX(Complex Dielectic Through intersecton)， The complex dielectric cross measurement method, developed by scientists and engineers at METER, can simultaneously measure the real and imaginary dielectric constants of soil and substrate. The built-in 4VM is a complex dielectric sensor that determines the real and imaginary parts of the dielectric constant by measuring the voltage amplitude at multiple circuit nodes. These independent measurements taken along the admittance plane will intersect the real and imaginary parts of the dielectric. By combining multiple admittance estimates, 4VM can correct errors and maintain accuracy, providing stability under any conditions regardless of changes in salinity.
