BDI - Model STS4 -Structural Testing System
Our Structural Testing System, the STS4, is the world’s only data acquisition system that has been designed by civil engineers expressly for structural testing. Intelligent sensors, Li-Ion battery power, wireless communication, and rugged design makes this system highly efficient and extremely easy to deploy on challenging projects.

4-Channel Wireless Nodes
Rugged four-channel data acquisition units powered by long-lasting Li-Ion batteries and utilize standard wireless network communication protocol.
Wireless Base Stations
Ruggedized network hubs generate the wireless network for the STS4 nodes and the user’s computer. Multiple Wireless Base Stations can be linked.
Intelliducers
Plug & Play feature dramatically reduces the time and effort required to track sensor cabling and associated settings.
Automatic Load Position Indicator
Tracks the position of the applied live load (e.g. test truck or train) during the load testing phase.
STS-LIVE
Allows the user to immediately initiate the system and begin testing with very little configuration required, while also giving the user some powerful tools.
- Automatically detects and configures STS4 hardware for Intelliducer sensor support
- Quickly configure sample frequencies, test durations, and other data acquisition parameters
- View recorded data in real time
- Adjust sensor excitation voltages and gains stages
- STS-Live automatically detects and supports STS4 Automatic Load Position Tracker (STS4-ALPT)
- Automatic zeroing option
- Seamlessly supports multiple Wireless Base Stations (STS4-WBS)
- Temperature compensation for sensors equipped with thermistors
- Real-time data filtering
- Control the Standby, Snooze, and Sleep power-saving modes
- TDMS data format allows easy importation into STS-VIEW, STS-CFA, or spreadsheet
- Designed for Windows®?10 and newer Operating Systems
- Import raw data files directly into STS-VIEW
- Supports CSI data files
- Process your data by applying different gage/correction factors and offset methods to either specified sensors or entire data files
- Remove data spikes and noise from data using the filtering feature that allows the user to graphically compare the original and filtered responses
- Compute and display neutral axis locations for flexural members
- Compute average responses from single and groups of sensors to calculate axial forces
- Data can be compared to computed responses calibrated from BDI’s WinSAC and Strand7 structural analysis software to visually evaluate the accuracy of a structural model
- Run an FFT on a given sensor output to evaluate the structural member’s frequency content
- Generate envelope files to determine the minimum and maximum responses from each sensor
- Extract processed data to a text file or spreadsheet complete with a sensor legend and envelope information
- Data decimation options can be used to reduce file size
- Merge multiple data files into one file
- Efficiently measure cable forces in the field
- Acceleration measurements used to determine in-situ cable forces
