What is the main difference between capacitive and resistive soil moisture measurement? Capacitive Soil Sensor detects changes in soil dielectric permittivity, offering better accuracy and corrosion resistance. Resistive sensors use conductive plates and are more prone to drift due to soil impurities and electrolysis. 2. Why is 316L stainless steel preferred in probe manufacturing? 316L stainless steel exhibits superior anti-corrosive and anti-oxidation properties, essential for longevity in saline, alkaline, and wastewater-impacted soils, and is internationally recognized by ASTM and ISO materials standards. 3. What testing standards are used to ensure Soil Sensor reliability? Comprehensive calibration and testing are conducted with reference to ISO 11277, GB/T 22314, ANSI/ASABE performance benchmark tests, and NIST-traceable calibration solutions to guarantee traceability and repeatability. 4. How should a Soil Sensor be installed for optimal performance? Install vertically, ensuring the probe is fully in contact with undisturbed soil, away from rocks and voids. Depth recommendation: 7–15cm for irrigation control, 20–60cm for field profiling. Use IP68-rated waterproof connectors for long-term outdoor deployment. 5. What output options are available for integration? Soil Sensor supports RS485 (Modbus RTU), 4-20mA, 0-5V analog, as well as wireless LoRa, Zigbee, NB-IoT in advanced models, allowing straightforward integration with PLCs, SCADA, and IoT platforms. 6. How is long-term sensor drift minimized? Advanced probe materials resist oxidation while fully potted electronics prevent moisture ingress. Periodic in-field “single-point” recalibration (every 24 months) is facilitated. Our multi-layer conformal coating meets MIL-STD-810F for added reliability. 7. What warranty and support are offered? All Soil Sensor units come with 3-year standard warranty (optionally 5), lifetime technical support, and global on-site commissioning services.
