The NI PXI-4220 is a full-featured data acquisition module with dual 16-bit inputs for quarter-, half-, and full-bridge sensors, such as strain gages, load cells, and pressure sensors. Bridge configuration, excitation, amplification, and filtering are fully programmable per channel. In addition, the PXI-4220 provides simultaneous-sample-and-hold capability to eliminate phase delay between channels. Each input channel of the module includes a 9-pin D-Sub connector for easy connection to bridge sensors, and programmable shunt and null calibration circuitry to improve measurement accuracy by eliminating gain and offset errors.
In addition, the PXI-4220 is designed to work with the NI LabVIEW graphical system design platform and NI-DAQmx driver and measurement services software. In LabVIEW, you can use the DAQ Assistant to configure the module and acquire data through a menu-based window, eliminating the need to manually program the device.
Reduce your setup time and total cost of ownership, and get a system you can use out of the box with National Instruments system assurance programs. System assurance programs include:
Installation and integration test of all individual hardware
Courtesy installation of system driver sets and application development environments
Three-year warranty and calibration coverage
Custom documentation plus a custom restore and startup utility
This service is only available for PXI, NI CompactRIO, and NI Compact FieldPoint systems.
National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:
Significant cost savings compared to individual repair incidents
Fault location, diagnostics, and repair by NI any time the system product fails
All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications
NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.
Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
