Model ASG-3000-HT Asphalt Strain Gauge

Dynamic asphalt strain gauges measure axial strain in the flexible pavement under high frequency (dynamic) conditions. 

Utilizing four active elements of a Wheatstone bridge circuit, this gage compensates for temperature, rejects bending strain (may also be configured to measure bending and reject axial strains), and compensates for lead resistance providing a sensor that is easily adaptable to most data acquisition systems without requiring additional signal conditioning.

This low-modulus, ruggedized sensor is built to withstand the high temperature and vibratory rolled compaction required for asphalt placement. 

Each sensor is individually calibrated and supplied with fabrication Quality-Control documentation.
