STS4-4 Node

Overview

The STS4-4 nodes are 4-Channel data acquisition devices with 4 analog and 4 temperature inputs per node. They are the 4th generation design based on our experiences over 25 years of structural testing and data acquisition designed specifically with our experience in mind.

There are four models to choose from depending on the application. A fully rugged outdoor version with intelligent sensor support (Intelliducer), and wireless or wired Ethernet communication options. A more economical version intended for monitoring applications where the nodes will be housed in outdoor enclosures or simply used in a laboratory application.
