Description
The STS4-4 Wireless Intelliducer Node is a rugged 4-channel wireless Data Acquisition node typically used for diagnostic live-load testing projects. The long battery life and ruggedized design makes this hardware ideal for use in harsh field conditions.
The STS4-4 Wireless Intelliducer Node has 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.
