Thiết bị đọc dây rung cầm tay (Vibrating Wire Analyzer) Campbell Scientific VWA
The Campbell Scientific Vibrating Wire Analyzer (VWA) is field ready and used to quickly measure a sensor, save the data, and communicate the results with custom PDF reports and spreadsheet output. The VWA uses spectral-analysis technology (VSPECT™), which can be helpful for reading sensors in electrically noisy environments. The large color display offers an easy-to-view graphical presentation of the sensor output and operation, and a Project File maintains Site/Sensor information for 40 unique sites with up to 22 sensors per site. Site/Sensor locations are geolocated, allowing the internal GPS to guide a user directly to a sensor location. Site/Sensor and user information can be created or edited on the device or with a computer using the included VwProjects software.
