Pressure Measurements Architecture
A virtual instrument consists of an industry-standard computer (PC) or workstation equipped with application software, hardware such as plug-in boards, and driver software, which work together to perform the functions of traditional measurement devices and instruments. With National Instruments pressure measurement solutions, you can take advantage of the analysis power and connectivity of your PC to develop a custom pressure measurement system that meets your exact application needs, while still giving you the flexibility to change the system as your application evolves.
Software
Software is an important component of any pressure measurement system. Whether your application requires simple data logging and monitoring or advanced analysis and control capabilities, choosing the right software package is essential.
Measurement Hardware
Measurement hardware determines your system’s physical capabilities – channel count, signal and sensor types, sampling rate, accuracy, portability, ruggedness, and more. The main hardware components for a pressure measurement system are signal connectivity, signal conditioning, and the digitizer. Depending on your application requirements, some of these components may be combined into a single unit.
Pressure Sensors
Pressure sensors should be selected based upon operating environment, desired measurement range, size, accuracy and cost. The output and connectivity will vary among the pressure sensor types but any of them can be easily integrated into a National Instruments pressure measurement system due to the flexibility of virtual instrumentation.
