✦Description of Soil Conductivity Sensor

Soil conductivity sensor is an instrument used to measure the electrical conductivity in soil. Conductivity is a measure of the electrical conductivity of a substance, which reflects the content of soluble substances in the soil and the soil’s ability to conduct electricity. Soil conductivity sensor can provide important information about soil fertility, salinization and moisture status by measuring the electrical conductivity in the soil. The measurement principle of the soil conductivity sensor is the AC bridge method. The electrodes of the soil conductivity sensor can directly measure the conductivity of soluble salt ions in the soil. To correctly measure this value, the current soil volume moisture content needs to be higher than about 20% of the soluble ions in the soil. Generally speaking, the value measured after the soil has been irrigated or rained is close to the actual level.

✦‌Advantages of soil conductivity sensors

1. High airtightness: The probe and the shell are vacuum poured with very high density epoxy resin. This sealing method can prevent moisture from entering the sensor, thereby improving the waterproof performance and allowing the sensor to have a longer life. 2. Corrosion resistance: The probe used is made of austenitic 316 stainless steel, which is not only rust-proof and anti-corrosion, but also non-electrolytic and has good corrosion resistance. The probe has high hardness and strong penetration. It can easily penetrate various soils, whether it is saline soil, yellow sand soil, paddy soil or alkaline soil, and can accurately measure the conductivity of the soil. 3. Stable signal: Made of imported chips, it not only has low power consumption, but also more sensitive response, and the transmitted signal is also very stable. The equipment has a complete protection circuit and a variety of interfaces are available for signal output. 4. Good interchangeability and anti-interference ability: The sensors have good interchangeability, ensuring the consistency and comparability of data during multi-point measurement. At the same time, the sensor has electrical isolation function, which can resist complex interference conditions on site, ensuring the stability and accuracy of data transmission. 5. Soil conductivity sensors are widely used in many fields. It is suitable for water-saving agricultural irrigation, greenhouses, flower and vegetable planting, grassland pastures, soil rapid testing, plant cultivation, scientific experiments, underground oil transportation, gas pipeline anti-corrosion monitoring and other fields.
