Detailed Description

这AVW216uses vibrating-wire spectral-analysis technology (VSPECT®). VSPECT®观察传感器信号,执行傅立叶变换和光谱分析(将时间序列转换为频谱中的单个正弦组件),并通过在可接受范围内识别最大信号,同时滤除环境和电气噪声来确定传感器频率。

AVW216分析仪模块还提供了许多自我检查诊断,例如振动元素信号强度,信号噪声比率,振动元件信号衰减比和不正确的信号响应。这些诊断可以在后台运行,以提供每个传感器的状况的连续反馈。

这AVW216typically transmits its data to an RF416 spread-spectrum radio that is connected to the data logger. The AVW216 can also be connected directly to the data logger.

Additional Compatibility Information

传感器

AVW216振动线频谱分析仪模块使我们的数据记录仪可以测量振动线应变量表,压力传感器,压电仪,倾斜度,裂纹器,饼干和负载电池。

通讯

这AVW216's internal spread-spectrum radio can transmit data to other AVW216 analyzer modules, RF416 spread-spectrum radios, and RF432 spread-spectrum radios. The AVW216 does not have a transparent mode, and therefore its internal radio cannot communicate with the RF415 radio.

Enclosure Considerations

AVW216需要一个干燥的,非调节的环境。当分析仪模块在现场时,建议使用坎贝尔科学围栏。AVW216具有内置的钥匙孔法兰,用于安装在外壳背板上。

Power Considerations

这AVW216is typically powered by the data logger's power supply.

经常问的问题

AVW21612

展开全部Collapse All

  1. 不。An AVW206, AVW211, or AVW216 is not capable of communicating with other AVW200-series modules.

  2. 这AVW216uses a 50 mW radio, and the AVW206 and AVW211 use 100 mW radios. If a radio with a higher output is desired, consider using theRF450with theAVW200。RF450在1 W处传输,这是AVW设备中收音机功率的10倍。

  3. 不需要AVW200系列模块,但是它们确实通过过滤有时存在的电噪声来减少错误读数的机会。

  4. It takes 2 s for the AVW200-series modules to acquire a measurement from each sensor. An AVW200-series module servicing two AM16/32B multiplexers, each with 16 vibrating-wire sensors, requires approximately 64 s to acquire data.

  5. Two probable causes are the following:

    • SerialOpen()instruction has not been added to the data logger code.
    • 这correct PakBus address setting has not been used in the AVW200 instruction.
  6. 每个多路复用器最多有16或32个传感器可以连接两个多路复用器。如果从每个传感器中排除温度测量值,则可能有32个传感器。

  7. AVW200必须通过电缆直接连接到数据记录仪。

    这AVW206, AVW2011, and AVW216 have built-in spread-spectrum radios tuned to different frequencies that allow the data logger to communicate with a remote AVW device through an appropriate radio link.
