Overview

The GRANITE™6 DAQ is a powerful core component for your complete data-acquisition system. The GRANITE 6 provides fast communication, low power requirements, built-in USB and Wi-Fi, modular design, and high analog input accuracy and resolution. It uses universal (U) terminals to allow a connection to virtually any sensor—analog, digital, or smart. The multipurpose DAQ is also capable of measuring static vibrating wire measurements.

GRANITE 6 2D (DXF)

Technical Description

The GRANITE™6 provides extreme measurement versatility, has multiple communications options, processes sensor responses to engineering units, performs calculations, generates alarms, and controls external devices. Data are stored in onboard, nonvolatile memory awaiting transfer to the end user via direct or remote access. The GRANITE™6 can generate real-time or event-driven data tables. These data can be further processed with high-level math functions and statistical summaries such as averages, standard deviations, and rainflow histograms.
