Overview

Connectivity

The National Instruments USB-9237 combines performance and

portability by making the NI 9237 C Series module compatible with the

bus-powered USB carrier for C Series modules. This module is ideal for

laptop applications because the USB port on the laptop powers all

acquisition and sensor excitation.

The USB-9237 uses four standard RJ50 connectors for rapid sensor

connection. You can add an RJ50 connector to any sensor using a

crimping tool, making sensor removal and insertion as easy as

connecting a PC to a network. For screw-terminal connectivity, the

NI 9949 accessory kit converts from RJ50 to 10 screw terminals. RJ50

cable kits are available in quantities of four 2 m cables and one 10 m

cable. For custom sensor wiring, cable kits are available with an RJ50

connector on one end and 10 signal wires on the other.

High-Speed Measurements

The NI USB-9237 module can take measurements at up to 50 kS/s on

four channels simultaneously and continuously stream the data back

over a Hi-Speed USB interface to serve applications from static load

or fatigue testing to high-speed fracture tests.

Software

The USB-9237 is shipped with the standard NI-DAQmx bundle that

includes Measurement & Automation Explorer (MAX) for conﬁguration

and testing; LabVIEW SignalExpress LE for out-of-the-box measurements,

logging, and data display; and an API/driver for languages such as

LabVIEW, ANSI C, C#, Visual Basic .NET, Visual Basic 6.0, Measurement

Studio, and LabWindows/CVI.

Sensor Compatibility

With full-, half-, and quarter-bridge completion, the USB-9237 can

measure a variety of load, force, and torque cells as well as some

pressure transducers and most strain gages.¹

Safety Isolation

• 30 V of overvoltage protection

• 60 V of CAT I channel-to-earth ground isolation

• 1000 V of transient withstand isolation

¹Quarter bridge requires accessory.
