STS4-4 Terminal Node

STS4-4 Terminal Node

Our STS4-4 Terminal Node is a 4-channel LAN data acquisition, DAQ, system designed to support a wide array of sensors such as strain transducers, LVDT’s, and accelerometers. Its on-board temperature correction feature makes it ideal for recording structural responses from up to 1,000 data channels for weeks, months, or years.  

Each STS4 node is based on the very reliable ethernet LAN protocol which provides unlimited flexibility in system configuration. Sensors are securely attached the node with terminal blocks and configured and controlled with STS-Live.

BDI STS technology has been the long-standing gold standard for field testing and monitoring because it has been developed by structural engineers specifically for use in difficult field conditions.
