AG Measurematics manufactures multi-channel strain measurement and data acquisition systems for structural health monitoring, static & dynamic load testing, and geotechnical instrumentation — with 24-bit resolution, up to 512 channels, and full bridge excitation support.
Key Specifications
Structural Instrumentation
Strain measurement is fundamental to structural engineering — from monitoring the health of bridges and dams to verifying the load-carrying capacity of new structures. Accurate, reliable strain data underpins every critical engineering decision.
AG Measurematics manufactures a complete range of strain measurement instruments — from portable single-channel indicators to 512-channel scanning systems for major infrastructure projects. All systems feature 24-bit ADC resolution, multiple bridge configurations, and field-proven reliability.
System
SMS-DL Series
Multi-channel strain gauge data loggers with 24-bit ADC resolution for long-term structural health monitoring. Battery-backed operation with SD card and USB data transfer.
SMS-DSI Series
High-speed strain measurement instruments for dynamic load testing, impact analysis, and vibration studies. Real-time display with peak capture and waveform recording.
SMS-512 Series
Large-scale multi-channel strain scanning systems for bridge load testing, dam monitoring, and structural testing of buildings and infrastructure. Up to 512 channels with sequential or simultaneous scanning.
Transducers & Cables
Complete range of strain gauge-based transducers (load cells, pressure cells, earth pressure cells, piezometers) and accessories for field and laboratory applications.
