Includes built-in radio
概述
The AVW216 is a vibrating-wire analyzer module that includes an internal 2.4 GHz spread-spectrum radio for wireless communication in many countries worldwide. With this vibrating-wire analyzer module, your data logger can measure vibrating-wire strain gages, pressure transducers, piezometers, tiltmeters, crackmeters, and load cells. These sensors are used in a wide variety of structural, hydrological, and geotechnical applications because of their stability, accuracy, and durability.

详细说明
AVW216采用振动线谱分析技术（VSPERT®）。vspect.®observes the incoming sensor signal, performs a Fourier transform and a spectral analysis (transforming the time series into individual sinusoidal components in the frequency spectrum), and determines the sensor frequency by identifying the largest signal in the acceptable range while filtering out environmental and electrical noise.
The AVW216 analyzer module also provides many self-checking diagnostics such as vibrating-element signal strength, signal-to-noise ratio, vibrating-element signal decay ratio, and incorrect signal response. These diagnostics can be running in the background to give continual feedback of the condition for each sensor.
AVW216通常将其数据发送到连接到数据记录器的RF416扩频无线电。AVW216也可以直接连接到数据记录器。

额外的兼容性信息
Sensors
The AVW216 Vibrating-Wire Spectrum Analyzer Module allows our data loggers to measure vibrating-wire strain gages, pressure transducers, piezometers, tiltmeters, crackmeters, and load cells.
Communications
AVW216的内部扩频无线电可以将数据传输到其他AVW216分析仪模块，RF416扩频无线电和RF432扩频无线电。AVW216没有透明模式，因此其内部无线电不能与RF415无线电通信。
外壳考虑因素
The AVW216 requires a desiccated, non-condensing environment. A Campbell Scientific enclosure is recommended when the analyzer module is in the field. The AVW216 has built-in keyhole flanges for mounting to an enclosure backplate.
功率考虑因素
AVW216通常由数据记录器的电源供电。

-
不可以。AVW206，AVW211或AVW216不能与其他AVW200系列模块通信。
-
-
The AVW200-series modules are not required, but they do reduce the chance of erroneous readings by filtering electrical noise that is sometimes present.
-
AVW200系列模块需要2秒，以从每个传感器获取测量值。AVW200系列模块维修两种AM16 / 32B多路复用器，每个都有16个振动线传感器，需要大约64秒获取数据。
-
两个可能的原因如下：
- TheSerialopen（）指令尚未添加到数据记录器代码中。
- 正确的Pakbus地址设置尚未在AVW200指令中使用。
-
Yes, using a null modem cable.
-
Two multiplexers, each with a maximum of 16 or 32 sensors per multiplexer, can be attached. If temperature measurements are excluded from each sensor, 32 sensors are possible.
-
The AVW200 must be wired directly to the data logger via a cable.
AVW206，AVW2011和AVW216具有内置的扩频无线电，调谐到不同的频率，允许数据记录器通过适当的无线电链路与远程AVW设备通信。
