Wireless Analog Input Node
The SG-Link
-200 is a 3-channel wireless sensor with a rugged, weatherproof
®
enclosure. It includes onboard PGA, filtering, and a high-resolution ADC for
precise measurement of a large range of sensor types including strain gauges,
load cells, pressure transducers, and accelerometers. The SG-Link-200
is ideal for both test and measurement and long term condition monitoring
applications.
Use this document to deploy the SG-Link-200 for data collection. This includes
electrical wiring, mounting the device, and using SensorConnect software to
configure the node, start sampling, and display data.
