  • Outputs for static-load or vibration measurements
  • Simple, low-cost wiring using RJ-45 telecom connectors
  • Measure all excitation voltages on the fly
  • Include temperature and displacement measurements
  • Locate remote unit up to 1000 feet from test system
  • Up to 6144 static channels supported by a single-mainframe VXI system
The Increasing Need for Strain and Bridge Measurements

In today's competitive marketplace innovative new materials and processes continue to expand the performance envelope of products ranging from cell phones to aircraft. Increased fuel efficiency, longer service life, less maintenance, lower cost, and improved manufacturability are all driving forces behind these efforts. Additionally, our world is full of structures that must be periodically evaluated to ensure key performance criteria are met.

Material test and performance qualification can encompass a wide variety of measurements including strain, load, pressure, and displacement. The challenges associated with this will depend on the specific application and can range from several channels for a small test article, to thousands of channels for a large structure, to many widely distributed channels that must be synchronized. Furthermore, as test demands vary so can the requirements placed on instrumentation.

New Test Requirements Increase Demands on Instrumentation

VTI has become the industry leader in bridge and strain measurements delivering complete solutions for a wide range of applications. Our precision instrumentation has a proven, fielded history of performance and durability throughout the world. There has been widespread adoption of our products for use in critical structural and fatigue test applications including next generation commercial and military aircraft qualification, power generation, transportation safety, and industrial structures.

Previous generations of instrumentation were not required to deliver the level of quality or precision measurement capability, or adhere to the levels of compliance and accuracy, that new materials being developed for reduced structural overhead, lower weight, and improved strength require. Today’s instrumentation must provide reliable data, first time, every time. We realize that this is true regardless of the application or unique measurement challenges that must be addressed.

Various applications will place greater emphasis on different selection criteria, so a one-size-fits-all instrumentation approach will certainly result in unwanted compromise. This is why VTI designs flexible, scalable solutions that can be optimized to meet specific application requirements.
