Modular Data-Logging Systems

With National Instruments modular data-logging systems, you can mix and match modules for different measurements types to build a customized data-logging system.

PC-Based or Stand-Alone

NI modular data-logging systems are either PC-based, which require connection to a PC, or stand-alone, which operate independently of a PC.

NI CompactDAQ

NI CompactDAQ is a modular, PC-based measurement system for USB or Ethernet. NI CompactDAQ consists of a chassis, modules, and a PC. The functionality of the device is defined by software running on the PC.

NI CompactRIO

NI CompactRIO is a modular, stand-alone measurement system that features a real-time processor and high-performance field-programmable gate array (FPGA). NI LabVIEW code can be deployed to the FPGA to control the functionality of the device so it can operate independently of a PC.

Mix and Match Sensor Types

Traditional data loggers include fixed configurations for measuring different sensor types. Using the NI C Series platform, you can build a flexible system to connect to any sensor type. Currently, you can choose from more than 50 C Series modules for different measurements including thermocouple, voltage, resistance temperature detector (RTD), current, resistance, strain, digital (TTL and others), accelerometers, and microphones. Because the modules contain built-in signal conditioning for extended voltage ranges or industrial signal types, you can usually connect wires directly from the C Series modules to your sensors.

Programmable With LabVIEW

You can program NI modular data-logging systems with custom functionality using NI LabVIEW, a graphical programming environment used by millions of engineers and scientists. Featuring intuitive graphical icons and wires that resemble a flowchart, LabVIEW makes it easy to take measurements from any sensor. Simply drag and drop controls and graphs to create custom user interfaces, and graphically wire together function blocks to define your own software functionality for logging data, alarming, triggering, reporting, and analyzing real-time data.
