Engineered specifically for strain, load, and pressure measurements, it combines high-resolution data acquisition with integrated signal conditioning in a single PXI Express slot. The PXIe-4330 is the industry-standard choice for engineers who prioritize absolute measurement accuracy and long-term stability in structural test cells and laboratory environments.<\/p>\n<h3 data-path-to-node=\"5\">1. High-Resolution 24-Bit Delta-Sigma Architecture<\/h3>\n<p data-path-to-node=\"6\">The PXIe-4330 is built around a <b data-path-to-node=\"6\" data-index-in-node=\"32\">24-\u0431\u0438\u0442\u043d\u044b\u0439 \u0434\u0435\u043b\u044c\u0442\u0430-\u0441\u0438\u0433\u043c\u0430 \u0410\u0426\u041f<\/b> per channel, providing exceptional dynamic range and noise rejection.
