The STS4 Core Data Logger is a ruggedized custom-built industrial computer that is designed to facilitate data acquisition in the harshest of environments. The core data loggers are field-proven to provide continuous and reliable operation for structural monitoring applications. The core data loggers are preconfigured to run the STS-CORE application that processes all raw data from our distributed data acquisition hardware. An STS4 Core Data Logger is typically delivered along with a turn-key structural monitoring system.


  • STS-CORE OS controlling Windows 8 Embedded StandardTM
  • Intel Atom processor with 2 GB RAM
  • 128 GB Solid State Drive (expandable)
  • Two Intel Gigabit Ethernet interface cards
  • +12v DC operation, 10w max operating power
  • STS-MONITOR application for system configuration
  • Ambient operation temperature -40 ͦ to +85 ͦC
  • Convection cooling requires no internal or external cooling fans in operating temp range
  • Humidity 5 to 95% non-condensing
  • Vibration resistant
  • Custom device drivers for third party hardware


  • TREND DATA: Captures statistical readings at a lower data rate for the purposes of viewing long-term trend data.
  • EVENT DATA: Captures higher-speed blocks of data based on a triggered threshold, typically from one or more sensors. Data is recorded pre- and post-trigger and customizable.
  • RAINFLOW: Captures stress cycle counts and binned into user defined stress ranges using ASTM E 1049-85
  • LIVE-LOAD: The system can be configured to run live-load tests, essentially a means to capture real-time data at the user-definead sample rate.
  • FREQUENCY: Raw data can be processed into the frequency domain and recorded. Frequency modes can be binned similar to RAINFLOW mode or used to calculate cable forces.
