Overview

nnnn

The NI 9235/9236 Measurement System measures 8 quarter bridge channels at 10 kS/s with 24-bit resolution, sending data to a host

nnnn

PC over USB, Ethernet or 802.11 Wi-Fi.

nnnn

Measurement Bundle Overview

nnnn

The hardware for an NI CompactDAQ single measurement bundle consists of a USB, Ethernet, or 802.11 W-Fi chassis and one of

nnnn

the over 50 NI C Series measurement-specific modules. These small rugged bundles are ideal for portable or distributed

nnnn

measurements.

nnnn

Chassis

nnnn

The chassis controls the timing for the module and handles communication with the PC over the USB, Ethernet, or 802.11 W-Fi bus.

nnnn

Additionally, all NI CompactDAQ chassis include four counter/timers that you can access through a digital I/O module like the NI 9401.

nnnn

Module

nnnn

NI 9235 and NI 9236 quarter-bridge strain gage modules are designed for higher-channel-count, dynamic strain measurement

nnnn

systems based on NI CompactDAQ, CompactRIO, or other compatible C Series hardware. Wth eight simultaneous channels per

nnnn

module, you can make more measurements with a smaller, more channel-dense system. Simultaneous sampling is important in

nnnn

higher speed acquisitions for which you need to compare results from different locations at a particular instant in time, such as impact

nnnn

tests.

nnnn

For a bridge-based module with a higher sampling speed or the ability to implement full-, half-, and quarter-bridge measurements, try

nnnn

the NI 9237 C Series simultaneous bridge module.
