Each sensor uses a solid-state transducer with a flexible silicon \u003cem\u003ewet\/wet\u003c\/em\u003e diaphragm, encapsulated in a 304L stainless steel housing (approx. 13\/16\" diameter) and finished with marine-grade epoxy so moisture can never work its way in and cause drift. A stainless steel micro-screen cap keeps silt, mud, and sludge from fouling the sensing element.\u003c\/p\u003e\n\n\u003cp\u003eThe WL400 outputs a two-wire 4–20 mA signal (convertible to 0.5–2.5 VDC across a 125 ohm resistor) that can run up to 3,000 ft to your logging device, so it drops easily into virtually any datalogger, telemetry system, monitor, or display. A vented cable provides automatic barometric pressure compensation, and a dynamic temperature-compensation system holds accuracy across a broad temperature range.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eWL400 submersible pressure transducer with 304L stainless steel housing\u003c\/li\u003e\n  \u003cli\u003eMolded-on, waterproof vented cable in the length you select (barometric compensation built in)\u003c\/li\u003e\n  \u003cli\u003eIntegrated \u003cstrong\u003etemperature\u003c\/strong\u003e measurement output\u003c\/li\u003e\n  \u003cli\u003eConfiguration\/calibration \u003cstrong\u003esoftware\u003c\/strong\u003e\n\u003c\/li\u003e\n  \u003cli\u003eQuick reference guide and factory calibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAccuracy of ±0.1% FS (full scale); ±0.2% over a 35°–70°F range\u003c\/li\u003e\n  \u003cli\u003eWet\/wet silicon diaphragm for excellent linearity and very low hysteresis\u003c\/li\u003e\n  \u003cli\u003e4–20 mA output; signal transmits up to 3,000 ft\u003c\/li\u003e\n  \u003cli\u003eAutomatic barometric compensation via vented cable\u003c\/li\u003e\n  \u003cli\u003eMarine-grade epoxy encapsulation and stainless micro-screen cap resist fouling and moisture\u003c\/li\u003e\n  \u003cli\u003e10–36 VDC supply; operating range −40° to +185°F\u003c\/li\u003e\n  \u003cli\u003eSix pressure\/level ranges (0–3, 0–15, 0–30, 0–60, 0–120, 0–250 ft) and cable lengths up to 500 ft\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThe WL400 is used for remote monitoring and recording of water level and pressure in a wide variety of settings, including:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eGroundwater level and well-depth monitoring\u003c\/li\u003e\n  \u003cli\u003ePump tests and aquifer\/sludge testing\u003c\/li\u003e\n  \u003cli\u003eSurface water flow, stream and river gauging, irrigation canals\u003c\/li\u003e\n  \u003cli\u003eTank, tide, and floating-dock level monitoring (including saltwater)\u003c\/li\u003e\n  \u003cli\u003eStormwater, flood analysis, and run-off studies\u003c\/li\u003e\n  \u003cli\u003ePipe flow and general water pressure measurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eConfiguration Guidance\u003c\/h3\u003e\n\u003cp\u003eSelect the \u003cstrong\u003epressure range\u003c\/strong\u003e that covers the maximum water level change expected for your application (not necessarily the total water depth) — choosing the smallest suitable range yields the best accuracy.
