SG-Link-200-OEM

Embeddable Wireless Strain/Analog Sensor Node, 2-Channel.

Contact us for details
Description

The SG-Link-200-OEM is a small wireless node with 2 analog input channels, ready for OEM integration. It includes onboard PGA, filtering, and high-resolution ADC for precise measurement of a large range of sensor types including strain gages, load cells, pressure transducers, and accelerometers.

Additionally, a digital pulse input channel allows easy integration to a hall effect sensor for reporting RPM or pulse count. The versatility and small form factor make the SG-Link-200-OEM easy to integrate into many applications.

 

Use Cases

Equipment Condition Monitoring

Small form factor and wide input range make it easy to embed wireless sensing into many applications.

Low power requirements enable long-term monitoring under battery power.

Test and Measurement

End-to-end data acquisition system reduces the time and cost of testing.

Remotely configure and collect data from a network of nodes in real time using SensorConnect.

Easily write your own custom software using the open source MicroStrain Communication Library (MSCL).

Impact and Event Monitoring

Event-Driven sampling allows for reporting only the data of interest around a predefined event.

User configurable pre- and post-event duration allow you to see the data that led up to the event, and how the data progressed back to normal conditions.
