準確可靠的水位壓力傳感器設計用于遠程監(jiān)測和記錄地下水抽水和污泥測試、雨水洪水分析和徑流以及地表水灌溉渠、溪流和河流測量中的水位和壓力數(shù)據(jù)。

美國global water水位傳感器WL400概述

Global Water 的 WL400 水位傳感器可為各種應用（包括惡劣環(huán)境中的應用）提供高精度的水位測量。投入式壓力傳感器具有動態(tài)溫度補償系統(tǒng)，可在較寬的溫度范圍內進行高精度測量。水位傳感器很容易適應所有數(shù)據(jù)記錄器、遙測、監(jiān)控設備和顯示器。

從 3 到 500 英尺的水位變化有多種深度范圍可供選擇。

美國global water水位傳感器WL400主要特征：

傳感器與大多數(shù)監(jiān)控設備兼容
高精度水位測量
不受泡沫、風或雨的影響
濕濕換能器消除了通氣管問題
自動氣壓和溫度補償
精心打造，可支持 3 英尺至 500 英尺的深度
可以測量液位和溫度
水位傳感器的浸入式壓力傳感器采用船用級環(huán)氧樹脂完全封裝，因此水分永遠不會泄漏或沿通氣管向下流，從而導致漂移或液位傳感器故障（與其他壓力傳感器一樣）。水位傳感器使用獨特的、高度靈活的硅膜片連接水和傳感元件。這種硅膜片可保護水位傳感器的電子設備免受潮氣影響，并為每個傳感器提供出色的線性度和極低的滯后。潛入式壓力傳感器的設計消除了與金屬箔隔膜相關的問題，金屬箔隔膜會隨著時間的推移而起皺和拉伸，從而導致漂移、線性和滯后問題。由于連接的通風電纜，水位傳感器還具有自動氣壓補償功能。它由不銹鋼微篩蓋保護，幾乎不可能被淤泥、泥漿或淤泥污染。水位傳感器的設計非常適合所有鹽水應用，包括潮位監(jiān)測、浮船塢等。

每個潛水壓力傳感器都有一個與水深成線性關系的兩線制 4-20 mA 輸出信號。操作水位傳感器需要 10 至 36 VDC 電壓，以便可以使用普通 12 VDC 電池系統(tǒng)操作水位傳感器。4-20 mA 信號從潛水壓力傳感器到測井設備的傳輸距離可達 3,000 英尺。一旦電纜出水，普通的雙絞線或電氣延長線可以拼接到通風電纜上。4-20 mA 信號可通過 125 歐姆電阻器上的電流信號轉換為 0.5 至 2.5 VDC。

Accurate and reliable Water Level pressure transducer designed for remote monitoring and recording of water level and pressure data in groundwater pumping and sludge tests, stormwater flood analysis, and run-off, as well as surface water irrigation canals, streams, and river gauging.

Overview
Global Water's WL400 Water Level Sensor provides highly accurate water level measurement for various applications, including those in severe environments. The submersible pressure transducers have a dynamic temperature compensation system, enabling high accuracy measurements over a wide temperature range. The water level sensor is easily adapted to all dataloggers, telemetry, monitoring equipment, and displays.

Multiple depth ranges are available from 3 to 500 feet of water level change.

Key Features:
Sensor compatible with most monitoring equipment
Highly accurate water level measurements
Not affected by foam, wind, or rain
Wet-wet transducer eliminates vent tube concerns
Automatic barometric pressure and temperature compensation
Well-built to support depths of 3ft to 500 ft
Can measure level and temperature
The Water Level Sensor's submersible pressure transducer is fully encapsulated with marine-grade epoxy so that moisture can never leak in or work its way down the vent tube to cause drift or level sensor failure (as is the case with other pressure sensors). The water level sensor uses a unique, highly flexible silicon diaphragm to interface between water and the sensing element. This silicon diaphragm protects the water level sensor's electronics from moisture and provides each sensor with exceptional linearity and very low hysteresis. The design of the submersible pressure transducers eliminates the issues associated with metal foil diaphragms, which tend to crinkle and stretch out over time, causing drift, linearity, and hysteresis problems. The water level sensor also has automatically barometric compensation due to the attached vent cable. It is protected by a stainless steel micro-screen cap, making fouling with silt, mud, or sludge virtually impossible. The water level sensor's design is great for all saltwater applications, including tide level monitoring, floating docks, etc.

Each submersible pressure transducer has a two-wire 4-20 mA output signal linear with water depth. From 10 to 36 VDC is required to operate the water level sensor so that the level sensors can be operated from common 12 VDC battery systems. The 4-20 mA signal can run up to 3,000 ft from the submersible pressure transducer to the logging device. Common twisted pair or electrical extension cord wire may be spliced to the vented cable once the cable is out of the water. The 4-20 mA signal may be converted to 0.5 to 2.5 VDC by dropping the current signal across a 125-ohm resistor.
