Strain, Pressure, and Force Measurement Hardware

Strain, pressure, and force input modules are key components in automated test systems because they allow for the measurement of mechanical properties directly from sensors. The input modules work by powering bridge-based sensors with a stable excitation voltage, then amplifying and filtering the small electrical signals they produce for accuracy. The conditioned signals are converted from analog to digital so the test system can process them, and finally, the data is sent to NI software like LabVIEW or FlexLogger for visualization, logging, and analysis.

When selecting strain, pressure, and force measurement input hardware, engineers consider key factors including sensor compatibility, excitation capability, measurement accuracy, channel count, sampling rates, and easy integration with test system software. Built-in signal conditioning, environmental durability, and scalability for future needs are also important differentiators among products.

NI strain, pressure, and force measurement products offer several advantages for automated test systems. They combine excitation, signal conditioning, data acquisition, and digitization in one integrated solution, reducing setup complexity. These products deliver high accuracy and low noise for reliable measurements, and scale easily from a few channels to large systems. NI hardware also works with LabVIEW and FlexLogger right out of the box, making it simple to configure tests, visualize data, and automate analysis. This integration saves time, improves consistency, and helps engineers turn sensor data into actionable insights.
