National Instruments PXI-4351 High precision data acquisition module

The National Instruments PXI-4351 is a high-precision data acquisition module based on the PXI bus standard, mainly used for measuring signals such as temperature and voltage. Supports multiple types of temperature sensors, such as thermocouples, resistance temperature probes (RTDs), and thermistors, to measure temperature data with high precision. It also supports multiple temperature measurement channels and can perform multi-point measurements simultaneously. By using advanced temperature sensors and measurement technology, coupled with a 24 bit Δ - ∑ ADC, high-precision temperature and voltage measurements can be carried out to ensure the accuracy and reliability of data.
