Jewell offers strain gauge-based sensors for asphalt and concrete. These sensors utilize active elements in the Wheatstone bridge strain circuit and measure the axial strength in pavements and concrete structures in high frequency dynamic conditions. Structural Health Monitoring of Concrete Foundations, Dams, Tunnels and Bridges Our CSG can be used in bridges to evaluate…
Dynamic asphalt strain gauges measure axial strain in flexible pavement under high frequency (dynamic) conditions. Utilizing four active elements of a Wheatstone bridge circuit, this gauge compensates for temperature, and rejects bending strain, 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.
Strain Gauge Technology Strain gauges are electrical devices used to measure the strain on the object to which they are bonded. On a fundamental level, strain gauges consist of a variable resistor whose resistance value changes when a force is applied to the material resulting in strain. As a result of this simple – yet…
Selecting the Right Sensor for Your Application Jewell Instruments manufactures high precision inertial sensors that incorporate Force Balance, MEMS or Electrolytic sensor technology. How to select the right sensor technology for a specific application generally depends on several factors. WHICH SENSOR TECHNOLOGY IS BEST? Selecting the right sensor technology might be seem like a daunting…
