Whether you are making strain measurements in a lab or rugged remote location, NI has the right measurement platform for your application. National Instruments has software options for quickly logging data to disk as well as for full programming environments for complex system architectures. With NI modular hardware and flexible software, you can create a strain measurement system that meets the specific and unique needs of your application.

Choosing a Strain Sensor and Measurement Device

Strain gages are fundamental sensing devices that function as the building blocks of many other types of transducers, including pressure, load, and torque, used extensively in structural test and monitoring applications. Even though strain gages are common, they are one of the most difficult types of sensors from which to condition and acquire reliable data. National Instruments offers a wide variety of devices for you to choose from to perform strain gage and bridge-based sensor measurements.

How-To Documents and Tutorials

The how-to guide for most common measurements provides information about making common sensor and signal measurements. Each of the following documents covers the operating principle for the corresponding signal/sensor and offers guidance on how to make that type of measurement. These documents help you understand what you need to know to quickly make your desired measurement.

Benefits of Using NI for Strain Measurements

  • Integrated signal conditioning and connectivity for resistive foil strain gages and bridge-based sensors to maximize your measurement accuracy and performance
  • Flexible virtual instrumentation gives you the ability to customize NI measurement hardware to meet the unique requirements of your strain measurement application
  • Fiber Bragg grating (FBG) optical strain gage measurement capabilities equip your system for harsh environmental requirements or distributed measurements over long distances
