AST Modules

Embedded Strain, Acceleration, Temperature

The Geodaq AST structural monitoring module is designed for embedment in concrete providing a complete measurement solution in a single robust housing. Each AST module includes a temperature compensated full bridge electrical resistance strain sensor, one 3-axis low-g accelerometer, and one high resolution temperature sensor. Optional versions available for fully isolated signal returns and overvoltage protection up to +/- 40 volts. The AST integrated measurement system provides the perfect solution for dynamic and static structural monitoring applications like drilled shaft testing and concrete pavement health monitoring. Fully conditioned analog output for easy integration with most data acquisition systems. Applications include drilled shaft testing, structural columns and pavements.
