National Instruments 781345-01 8-Channel PXI Strain/Bridge Input Module
The National Instruments 781345-01 is an 8-channel PXI Express Strain/Bridge Input Module. It is also known as the PXIe-4331 unit. It is designed for high-speed data acquisition and precise signal conditioning. This module is ideal for dynamic measurements of strain, load, and pressure that makes it suitable for high-density measurement systems. This NI 781345-01 features 24-bit delta-sigma ADCs with analog prefiltering that ensure accurate and reliable data acquisition across all channels.
The 781345-01 supports simultaneous sampling that allows for precise synchronization and timing across multiple inputs. Each channel of this module is equipped with software-selectable bridge completion modes like full, half, and quarter-bridge configurations. The module also supports shunt calibration along with internal and external calibration options to ensure measurement accuracy.Programmable excitation voltages per channel, ranging from 0.625 V to 10 V, cater to diverse sensor requirements. This input module includes features such as remote sensing and short-circuit protection to enhance measurement reliability. The NI 781345-01 offers extensive filtering capabilities that include antialiasing and digital filters, to minimize noise and improve signal quality. It has a FIFO buffer size of 1,023 samples that enables efficient data transfer through Direct Memory Access (DMA) or Programmed I/O. The module supports a wide range of sampling rates, from 1 S/s to 102.4 kS/s, which allows users to tailor the data acquisition process to their specific needs. The 781345-01 module is designed for robust performance.It operates within an ambient temperature range of 0 °C to 55 °C and can withstand storage temperatures as low as -40 °C.
The module is built to meet stringent safety and electromagnetic compatibility standards that ensure reliable operation in various industrial and laboratory environments. With a compact 3U PXIe form factor, the 781345-01 integrates seamlessly into PXI Express or PXI Express hybrid slots. The overall dimensions and weight of this module are 16 cm × 10 cm (6.3 in. × 3.9 in.) and 152 g (5.3 oz). This Express strain/bridge input module can be installed at the maximum altitude of 2000 MSL. But the commissioning should be done by a highly qualified person. For more details, you can consult the 781345-01 user manual.
