STS4: The latest in proven structural testing technology


The new STS4 from BDI is the world’s only data acquisition system that has been designed by structural engineers for structural testing. This next-generation wireless system is rugged, highly efficient, and now supports long-term monitoring applications. Once you see how much time this system saves you in the field, you won’t use anything else!


The STS4 is smaller, lighter, and will make your testing operation even more efficient:

  • No programming required—Our STS-LIVE software is very easy to use!
  • STS4 Base Stations have wireless repeater capabilities, increased range, and POE support.
  • Hardware and software can now support long-term monitoring projects.
  • Efficient power saving modes for longer battery life.
  • Increased sensor voltage input ranges and programmable excitation voltages.
  • Auto-temperature compensation support for sensors with thermistors.
  • Compatible with existing STS-WiFi hardware and WinSTS Software.
  • STS4 Extension Nodes: Communication and power for up to 16 data channels at a much lower cost than a full STS4 system.
