Sensaphone FGD-0090 Soil Moisture Sensor

Sensaphone FGD-0090 Soil Moisture Sensor The FGD0090 is a 4-20mA soil moisture sensor. The FGD-0090 operates by measuring the dielectric constant of the soil using capacitance/frequency domain technology. The sensor comes with factory calibrations for mineral soils, potting and soils and rock wool. *Note: 24VDC power supply (such as FGD-0070) required FGD-0090 Soil Moisture Sensor Specifications Dimensions: 3.5 x .27 x .7 x | 89mm x 18 mm x 7mm Operating Temperature Range: -40° to 140°F | -40° to 60°C Accuracy: ±6% VWC with generic calibration for supported growing media up to 65% VWC, above which accuracy lessens. Increased accuracy can be achieved with a medium-specific calibration. 4-20mA output Scale: 0 - 100% Note: Element Tolerance to IEC 60751 edition 2.0, par 5.1.2 Settling Time: 4 seconds FGD0090 Soil Moisture Sensor Includes 1 x FGD0090 Soil Moisture Sensor FGD0090 Soil Moisture Sensor Support Cut Sheet
