50 kS/s/channel, Bridge Analog Input, 4-Channel C Series Strain/Bridge Input Module
Overview
The NI-9237 includes all the signal conditioning required to power and measure up to four bridge-based sensors simultaneously. The module provides strain or load measurements with zero interchannel phase delay. It also has 60 VDC isolation and 1,000 Vrms transient isolation, providing high-common-mode noise rejection and increased safety.
You can program the NI-9237 for use with half-bridge and full-bridge sensors with built-in excitation. The four RJ50 jacks provide direct connectivity to most torque or load cells and offer custom cable solutions with minimal tools.

- Product (Part Number)DescriptionRecommended use casesFlexLogger Professional (785748-3501)FlexLogger Professional, Subscription License, Download
Recommended for automated, extensible data logging with NI data acquisition (DAQ) hardware. Automate tests using alarms, triggers, and events, and expand capabilities with plug-ins.
Key Features
- Multichassis synchronization—Synchronize multiple NI chassis for accurate, time-aligned measurements across high channel counts.
- Logging triggers—Start, stop, or segment data recording automatically based on sensor thresholds or other conditions to capture only what matters.
- Events—Respond to specific occurrences during a test, such as activating equipment when a condition is met (for example, start cooling fans when temperature exceeds a limit).
- Automation APIs—Control and monitor FlexLogger from external applications (Python, NI LabVIEW, or NI TestStand), enabling integration into larger automated test systems.
- Calculation channels—Perform real-time math on acquired data (averages, RMS, custom formulas) to track derived measurements as the test runs.
- Plug-ins—Extend FlexLogger with custom LabVIEW or Python plug-ins to integrate third-party hardware, perform custom analysis, or connect to lab systems.
- CAN/LIN logging—Acquire and log automotive network data alongside sensor measurements for complete vehicle or subsystem testing.
