Common Configurations for Strain/Pressure/Force/Load Data Logging

National Instruments offers a wide range of measurement system options to log data from strain gages or other bridge-type sensors. These sensors might also include pressure, load, or force. Some options for strain-logging systems are listed below.

Each data-logger configuration contains a description and a parts list. The parts list includes the measurement hardware - signal connectivity, signal conditioning (if required), digitizer, and other necessary items. The list also includes a recommended software package for that application and common options for each configuration.

If you do not see a system that meets your data-logging application needs, contact a National Instruments sales representative to help you configure a customized system for your specific application.

High-Accuracy, Desktop 32-Channel Strain Gage Data Logger
This system measures up to 32 strain gage or other bridge-type sensors with sensor connectivity through screw terminals on the front-mounting terminal block.

Isolated Strain Gage Data Logger
This data logger includes the digitizer, signal conditioning, and sensor connectivity necessary to complete a 44-channel strain gage (or other bridge-type sensor) data-logging system with the plug-and-play ease of a USB connection to your computer.

Low-Cost Strain Gage Data Logger
This system is ideal for portable applications. It uses the NI SCC signal conditioning system, a PCI data acquisition board, and a PC for a data logger capable of logging up to 16 quarter-, half-, or full-bridge strain gage (or other bridge-type sensor) channels. This modular system is recommended for use when application needs might expand beyond basic strain measurements.

Distributed Strain Gage Data Logger
The NI Compact FieldPoint modular distributed I/O system is ideal for measurements that must be distributed from the computer. This system provides up to 32 channels of half- or full-bridge strain gage inputs and comes in a rugged, industrial-grade package that is excellent for installation in harsh environments.

High-Channel-Count Strain Gage Data Logger
This high-density, high-accuracy strain measurement system features up to 288 channels and direct screw-terminal connectivity. With this modularity, you can easily expand as your application needs change.

Rugged, Industrial 64-Channel Strain Gage Data Logger
Choose the NI PXI platform for your data logging application if you want a compact, clean, rack-mountable system suitable for more industrial environments. This system is designed to measure up to 64 strain gage or other bridge-type sensors with sensor connectivity through screw terminals on the front-mounting terminal block.

Portable 16-Channel Strain Gage Data Logger
This system uses the NI SCC signal conditioning system, a PCMCIA data acquisition device, and a laptop.
