Introduction: The sensor is a high-precision, high-sensitivity soil moisture sensor based on the principle of frequency domain reflection and using high-frequency electronic technology. It is suitable for the measurement of soil temperature and moisture. Fast response and stable output. It is less affected by soil salinity and is suitable for various soil types. It can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, and completely waterproof. The sensor is widely used in scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland and pastures, soil rapid measurement, plant cultivation, sewage treatment, grain storage and the measurement of water content and temperature of various particulate matter. Features: 1. High measurement accuracy, fast response and good interchangeability. 2. It is less affected by soil salinity and can be applied to various soil types. 3. The electrode is made of stainless steel with special treatment, which can withstand strong external impact and is not easy to be damaged. 4. Completely sealed, resistant to acid and alkali corrosion, and can be buried in soil or directly into water for long-term dynamic testing. 5. High precision, fast response, good interchangeability, probe insertion design ensures accurate measurement and reliable performance. Technical parameter: Measurement parameters: soil volumetric moisture content Measurement unit: 0~100% (30%, 50% and other ranges can be selected or any range can be customized) Measurement accuracy: ±2% within 0-50%, ±3% within 50-100% (m³/m³) Working temperature: -40℃~+60℃ Supply voltage: 12~24V DC Core chip temperature resistance: 85℃ Protection class: IP68 Probe material: Anti-corrosion special electrode Sealing Material: Black Flame Retardant Epoxy Default cable length: 2 meters, cable length can be customized Dimensions: probe length 55mm; probe diameter 4mm, outer diameter 50mm Output signal: 1.
