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.

This geotechnical MEMS tiltmeter is available in uniaxial and biaxial configurations. It presents a robust and rugged design for outdoor geotechnical use, but with the benefit of low-cost MEMS technology and ±5VDC, 0-5 VDC, or 4-20 mA output signals. It is an effective tilt sensing solution for platform leveling/positioning, structural monitoring, construction monitoring, industrial machinery positioning, radial gate measurement & control.
The 750-150 tiltmeter is a high-performance, single-axis tilt sensor with the same specifications as the 750-100, but housed in a larger, more ruggedized, with an IP66 enclosure. The fluid damped mechanism delivers superior noise rejection in high shock and vibration environments as well as excellent output stability. Units are available with a 6-pin connector, pin-terminals, or a wired connection option. Available outputs include 0-5V and 4-20mA. Custom input ranges, filters, and temperature compensation are also available on request.
