Deskripsi
Sensor cerdas kelembaban tanah ini mempunyai desain dua lapis untuk pemasangan yang mudah. Sensor ini mengintegrasikan Sensor ECH2O ™ EC-5 yang terbukti di lapangan dan A / D 12-bit. Memberikan akurasi ± 3% dalam kondisi tanah, dan ± 2% akurasi dengan kalibrasi. Pembacaan disediakan langsung dalam kadar air volumetrik. Sensor ini dirancang untuk menjaga sensitivitas rendah terhadap salinitas dan efek tekstur.
Fitur
- Mengukur volume tanah sebesar 0,3 liter
- Volume pengukuran yang lebih kecil untuk digunakan dalam wadah atau pengukuran pada berbagai kedalaman
- Sirkuit frekuensi tinggi (70 MHz) memberikan akurasi yang baik bahkan di tanah dengan salinitas tinggi dan berpasir.
- Kompatibel dengan Onset stand-alone dan Weather Station berbasis web
Spesifikasi
Measurement Range
In soil: 0 to 0.550(m³/m³)
Extended range: -0.401 to 2.574 m³/m³ (full scale)
The sensor is capable of providing readings outside the standard volumetric water content range. This is helpful in diagnosing sensor operation and installation. See User Manual for additional information.
Accuracy: ±0.031 m³/m³ (±3.1%) typical 0 to 50°C (32° to 122°F); ±0.020 m³/m³ (±2%) with soil specific calibration.
This is a system-level accuracy specification and is comprised of the ECH2O probe’s accuracy of ±0.03 m³/m³ typical (±0.02 m³/m³ soil specific) plus the smart sensor adapter accuracy of ±0.001 m³/m³ at 25°C (77°F). There are additional temperature accuracy deviations of ±0.003 m³/m³ / °C maximum for the ECH2O probe across operating temperature environment, typical <0.001 m³/m³ / °C. (The temperature dependence of the smart sensor adapter is negligible.)
Resolution: 0.0007 m³/m³ (0.07%)
Soil probe dimensions: 89 x 15 x 1.5 mm (3.5 x 0.62 x 0.06 in.)
Weight: 180 grams (6.3 oz)
Decagon ECH2O probe part No.: EC-5
Sensor operating temperature: 0° to 50°C (32° to 122°F).
While the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F) and up to 75°C (167°F), the soil moisture data collected at these extreme temperatures is outside of the sensor’s accurate measurement range.
Volume of influence: 0.3 liter (10.1 oz)
Sensor frequency: 70 MHz
Bits per sample: 12
Number of data channels: 1
Note: A single smart sensor-compatible HOBO logger can accommodate 15 data channels and up to 100 m (328 ft) of smart sensor cable (the digital communications portion of the sensor cables)
Measurement averaging option: No
Cable length available: 5 m (16 ft)
Length of Smart Sensor network cable: 0.5 m (1.6 ft)
– The CE Marking identifies this product as complying with all relevant directives in the European Union (EU)
