NI 9235/9236 Measurement System
8 Ch Quarter-Bridge Module for USB, Ethernet, and Wi-Fi
- Bundle includes measurement module and 1-slot NI CompactDAQ chassis
- USB, Ethernet, and 802.11 Wi-Fi connectivity
- 24-bit, simultaneous ADCs
- 10 kS/s/ch dynamic strain measurements
- Built-in voltage excitation for quarter-bridge sensors
- 120 Ω strain gage measurements with the NI 9235
The NI 9235/9236 Measurement System measures 8 quarter bridge channels at 10 kS/s with 24-bit resolution, sending data to a host PC over USB, Ethernet or 802.11 Wi-Fi.
Measurement Bundle Overview
The hardware for an NI CompactDAQ single measurement bundle consists of a USB, Ethernet, or 802.11 Wi-Fi chassis and one of the over 50 NI C Series measurement-specific modules. These small rugged bundles are ideal for portable or distributed measurements.
Chassis
The chassis controls the timing for the module and handles communication with the PC over the USB, Ethernet, or 802.11 Wi-Fi bus. Additionally, all NI CompactDAQ chassis include four counter/timers that you can access through a digital I/O module like the NI 9401.
Module
NI 9235 and NI 9236 quarter-bridge strain gage modules are designed for higher-channel-count, dynamic strain measurement systems based on NI CompactDAQ, CompactRIO, or other compatible C Series hardware. With eight simultaneous channels per module, you can make more measurements with a smaller, more channel-dense system. Simultaneous sampling is important in higher speed acquisitions for which you need to compare results from different locations at a particular instant in time, such as impact tests.
For a bridge-based module with a higher sampling speed or the ability to implement full-, half-, and quarter-bridge measurements, try the NI 9237 C Series simultaneous bridge module.
