Little Sensors, Big Ideas

Introduction

Fast, small, and rugged, the new HS-Link 100KHz high speed wireless node delivers the versatile MicroStrain wireless sensing platform to applications that require speed. With maximum sample rates up to 100 kHz, and support for most types of analog sensors, including accelerometers, strain gauges, load cells, & pressure sensors, the node includes full strain gauge conditioning and programmable offset.

The node is designed to log data to internal memory and upload wireless data to a host computer once logging is complete. Data is collected during periodic, user definable sampling sessions, at rates up to 100 kHz. Burst data are temporarily stored in a sample buffer (125,000 data points) and are then transferred to non-volatile, internal flash memory.

The bi-directional RF communications link can trigger logging from 70 meters (up to 100 m possible), or request that stored data be transmitted to the host PC for data acquisition and analysis.

The node’s scalable system architecture and programmable sensor interface enables a large network of nodes to simultaneously store dynamic data with node-to-node synchronization of ±4 μseconds.
