250-40561 MAS-1 Soil Moisture Sensor

MAS-1 Soil Moisture Sensor 4-20mA

$330.00

Ships in 5 - 7 business days from time of order.

Model: 250-40561

The 250-40561 MAS-1 Soil Moisture Sensor offers a standard 4-20 mA output that is common with PLCs, Irrigation controllers and Data Loggers. 5M (16ft)) Cable lenght is standard, custom cable length up to 250ft)

The MAS-1 determines volumetric water content (VWC) by measuring the dielectric constant of the media using capacitance/frequency domain technology. The sensor uses a 70 MHz frequency, which minimizes salinity and textural effects, making the MAS-1 accurate in almost any soil or soil-less media. Factory calibrations are included for mineral soils, potting soils, and rockwool.

The MAS-1 delivers research-grade accuracy at a price that makes large sensor networks economically practical. You can adequately characterize your site with sensors at multiple depths and locations, even if you're on a tight budget.

    • Interface: standard 4-20 mA analog transmitter

    • Supply voltage: 12-32 Vdc continuous

    • Output current: 4-20 mA

    • Overvoltage protection: Yes

    • Settling time: 4 seconds

    • Wiring:

      • Red Wire: (+) supply

      • Black Wire: (-) output

      • Shield: not connected

    • Sensor Type: Volumetric Water Content (VWC)

    • Range: 0-100% VWC typical

    • Resolution: Depends on current measurement (data aquistion) device

    • 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.

    • Output: 4-20 mA current proportional to VWC
