美国GLOBAL WATER水位传感器WL400

准确可靠的水位压力传感器设计用于远程监测和记录地下水抽水和污泥测试、雨水洪水分析和径流以及地表水灌溉渠、溪流和河流测量中的水位和压力数据。

美国global water水位传感器WL400概述:

Global Water 的 WL400 水位传感器可为各种应用(包括恶劣环境中的应用)提供高精度的水位测量。投入式压力传感器具有动态温度补偿系统,可在较宽的温度范围内进行高精度测量。水位传感器很容易适应所有数据记录器、遥测、监控设备和显示器。

 

从 3 到 500 英尺的水位变化有多种深度范围可供选择。

美国global water水位传感器WL400主要特征:

传感器与大多数监控设备兼容

高精度水位测量

不受泡沫、风或雨的影响

湿湿换能器消除了通气管问题

自动气压和温度补偿

精心打造,可支持 3 英尺至 500 英尺的深度

可以测量液位和温度

水位传感器的浸入式压力传感器采用船用级环氧树脂完全封装,因此水分永远不会泄漏或沿通气管向下流,从而导致漂移或液位传感器故障(与其他压力传感器一样)。水位传感器使用独特的、高度灵活的硅膜片连接水和传感元件。这种硅膜片可保护水位传感器的电子设备免受潮气影响,并为每个传感器提供出色的线性度和极低的滞后。潜入式压力传感器的设计消除了与金属箔隔膜相关的问题,金属箔隔膜会随着时间的推移而起皱和拉伸,从而导致漂移、线性和滞后问题。由于连接的通风电缆,水位传感器还具有自动气压补偿功能。它由不锈钢微筛盖保护,几乎不可能被淤泥、泥浆或淤泥污染。水位传感器的设计非常适合所有盐水应用,包括潮位监测、浮船坞等。

 

每个潜水压力传感器都有一个与水深成线性关系的两线制 4-20 mA 输出信号。操作水位传感器需要 10 至 36 VDC 电压,以便可以使用普通 12 VDC 电池系统操作水位传感器。4-20 mA 信号从潜水压力传感器到测井设备的传输距离可达 3,000 英尺。一旦电缆出水,普通的双绞线或电气延长线可以拼接到通风电缆上。4-20 mA 信号可通过 125 欧姆电阻器上的电流信号转换为 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.
