Overview

 

xStrain is a distributed digitizer for monitoring Wheatstone Bridge sensors in SHM system. It offers an affordable and flexible solution for field/remote acquisition of data from sensors with very low voltage output (mV). xStrain is designed for applications in harsh environments and small places. Size, weight, and cabling are critical design requirements in almost any installation. By taking advantage of the extreme performance and small size, xStrain is able to deliver unprecedented control and acquisition capabilities in a compact, rugged package with extreme industrial certifications and ratings for operation in harsh industrial environments. Temperature ranges of -40° to 55° C (-40° to 131° F) and a variety of international safety, electromagnetic compatibility (EMC), and environmental certifications and ratings are all available with xStrain.

xStrain can be used as standalone digitizer or as a part of daisy chain SHM system. Series of xDAS units can be connected in a network using standard CAT5e cable for easy installation. xStrain can accept various type of sensors required for SHM instrumentation like: strain gauge transducers, load cell sensors, pressure sensors, displacement sensors, etc.
