National Instruments PXIe-4330 PXI Strain/Bridge Input Module

The PXIe-4330 (Part Number: 781346-01, 194953D-02L) is a high-performance Strain/Bridge Input Module from National Instruments. The built-in ADC has the resolution of 24-bits. The NI PXIe-4330 Strain/Bridge Input Module offers eight analog input channels. The module makes use of the simultaneous mode of operation for the sampling of signals. The instrument offers exceptional throughput and high accuracy. It also incorporates synchronization capabilities, which makes it suitable for critical industrial requirements that need high accuracy. The PXIe-4330 Strain/Bridge Input Module incorporates digital filters implemented separately for each channel in use. They enable the user to reduce or remove the noise from the signal under test.

The PXIe-4330 module has a FIFO buffer size of 1,023 samples. The data transfers on this module are carried out through programmed I/O and direct memory access. The frequency sample rate of the device is 1 S/s to 100 S/s for the increment of 1 S/s. The sample rate for the 100 S/s increment is from 100 S/s to 25.6 kS/s. The CMRR value for NI PXIe-4330 Strain/Bridge Input Module is 85 dB.

The National Instruments PXIe-4330 module offers three different bridge completion modes: full, half, and quarter modes of operation. The user can select any of the modes per channel through software. It also offers software selectable shunt calibration per channel. The values offered for the calibration are 33.333 kΩ, 50 kΩ, and 100 kΩ. The maximum tolerance is 0.1%. It has the stability of 10 ppm/℃, which helps achieve the high measurement accuracy for NI PXIe-4330 Strain/Bridge Input Module.
