National Instruments offers a wide variety of pressure measurement solutions ranging from simple, secure Wi-Fi devices to high-channel rack-mountable systems. You can integrate all NI pressure measurement systems with other measurements and sensor types because of the modular design. Software options are available for configuration-based loggers as well as full programming environments.
Pressure measurements are one of the fastest growing types of physical measurements. You can make pressure measurements in various mediums using different channel counts. Depending on the desired accuracy, range, and expense, you have several sensor options for measuring pressure. National Instruments offers a wide variety of devices for you to choose from to make pressure measurements.
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.
NI CompactDAQ is a portable, rugged data acquisition platform that integrates connectivity and signal conditioning into modular I/O for directly interfacing to any sensor or signal. Use NI CompactDAQ with NI LabVIEW software to customize how you acquire, analyze, present, and manage your measurement data. National Instruments provides programmable software, high-accuracy measurements, and local technical support to ensure you meet your exact measurement application requirements from research to development to validation.
NI CompactRIO combines an open embedded architecture with small size, extreme ruggedness, and hot-swappable industrial I/O modules, and is powered by the LabVIEW reconfigurable I/O architecture. Each system contains an FPGA for custom timing, triggering, and processing with a wide array of available modular I/O to meet any embedded application requirement.
The NI PXI platform provides a variety of chassis, controller, and module options that give you the power to create a measurement system that meets your application’s specific needs. The platform is recommended for highly accurate pressure measurements. The NI PXIe-4330 has an accuracy of up to 0.02 percent and the NI PXIe-4331 can sample up to 102.4 kHz. These solutions can scale to thousands of pressure measurement channels for large applications.
