Why Should You Use a Vibrating-Wire Data Logger?

在这次短暂的采访中，乔什·棕色，基础设施集团的市场产品经理，分享了使用振动线数据记录器的一些好处，例如CRVW3 3通道振动线Datalogger。杰希被博客编辑器的罗宾德斯林格采访了。

Interview Q&A

什么是使用的振动线数据记录器？

You might not know this, but vibrating-wire sensor technology has been around since 1899. Since then, the use and application of vibrating-wire sensors has grown significantly. Today, these sensors are recognized as an industry standard in dam and levee monitoring, geotechnical monitoring, and structural health monitoring. Campbell Scientific is committed to helping these industries be successful by obtaining the best vibrating-wire measurement possible. So, what did we do? We designed vibrating-wire data loggers that use our patented VSPECT^®测量技术，多种通信选项和多种形式因素。

One example of a Campbell Scientific vibrating-wire data logger is the CRVW3. We built the CRVW3 with our dam and levee monitoring customers in mind. But really, the measurement reliability and the breadth of vibrating-wire technology make it suitable for many different applications where you need geotechnical measurements.

What makes you excited about the CRVW3?

关于CRVW3有很多理由对CRVW3兴奋。CRVW3是坚固设计的完整包装。另外，部署很容易。这使其成为您预期恶劣条件的简单安装。CRVW3也适用于您的人员在现场有限的情况下或它们具有最小的仪器体验。

With a CRVW3, you can expand your data acquisition network without having to do extensive site work. For example, by using the CRVW3 you are able to decrease trenching efforts by locating the data acquisition system closer to the measurement locations, and you don’t have to install expensive communication or power infrastructure. Because it’s a three-channel data logger, the CRVW3 gives you adequate measurement density, while minimizing your overall equipment needs and cost.

使用CRVW3内置无线电，您可以在监控网络中无线通信。这有助于您最小化广泛损坏的潜力 - 例如，由电涌或照明撞击引起。

We really hope users around the world will take advantage of the CRVW3’s design for their vibrating-wire measurements. Like all of our products, this data logger is backed by the Campbell Scientific reputation for measurement quality.

CRVW3如何与其他产品不同？

Earlier, I mentioned VSPECT^®。这是专利的VSPET^®measurement technology that our vibrating-wire data loggers use. VSPECT^®technology uses spectral analysis techniques to filter noise caused by things like transmission lines, generators, pumps, long cable lengths, and degraded sensor signals. To further eliminate measurement noise, you can configure the CRVW3 to only “listen” to the specified frequency range of the sensors.

CRVW3还使用我们的Pakbus通信协议，因此您可以轻松地将其添加到您的坎贝尔科学产品网络中。配置CRVW3后，它将在其他CRVW3S的网络中自动发现在现场的其他CRVW3或聚合站。当您添加或删除测量节点时，此自动发现功能使监控网络能够自我修复，或者即使当其他节点丢失与网络通信时，即使丢失。此外，每个CRVW3在与聚合站站或远程数据收集站点的通信丢失或中断的情况下存储其自己的数据。

您如何使用CRVW3与其他Campbell Scientific产品？

您可以使用CRVW3作为独立产品，或者您可以在较大的无线电链接网络中使用它作为一个组件。您应该知道，当您使用无线电链接网络时，所有组件必须使用相同的射频。为了帮助您，我们提供了几种不同的无线电选项，因此您的CRVW3可以与其他坎贝尔科学产品沟通。此外，我认为你会发现使用我们的网络计划软件将使您的配置更简单。

As your measurement needs expand, you can network the CRVW3 with your other Campbell Scientific stations. Then you can measure a variety of parameters related to weather monitoring, power, lightning warning, slope stability, and flow.

CRVW3和CRVW3-NE之间有什么区别？

I’m glad you asked. The CRVW3 is factory integrated with a power supply and a weatherproof enclosure. TheCRVW3-NEhas the same electronics as the CRVW3, but it doesn’t have an enclosure and battery. So, with the CRVW3-NE, you can select your own enclosure and battery.

Is the CRVW3 new?

We released the CRVW3 about three years ago and followed it up with the CRVW3-NE about a year later. We’ve had positive feedback from our customers about these products, and we’d like more people to learn about them. We are confident in the capability of our vibrating-wire data loggers, and we look forward to helping customers incorporate them into their monitoring solutions.
