Sutron SatLink3

SatLink3 is a data logger with a built-in satellite transmitter that is especially designed for hydrometry, meteorology, and environmental monitoring.

The SatLink3 (SL3) provides a cost-effective way to measure, log, calculate, and transmit data from remote locations around the world. The unit monitors 32 independent measurements of most hydrological, meterological, environmental, or related sensors. SL3 has built in support for all CGMS satellites including GOES, Eumetsat, Insat, and MTSAT for operation anywhere. Most often used directly connected to sensors and transmitting data on a user-set schedule, the SatLink3 has options for cellular and Iridium communications. 

Satlink3 builds upon Sutron's 30 years' experience providing reliable satellite communications. Satlink3 does everything Satlink2 did with the following enhancements:

  • Expanded measurements from 16 to 32
  • Improved analog accuracy and additional analog channels
  • Expanded SDI capacity with 2 independent SDI-12 inputs
  • Optional cell/Iridium modems to redundant
