SDI-LINK (WSDI-M, WSDI-S, WSDI-SIO)
 
SDI-LINK is composed of two parts -- Master Modules that connect to SDI-12 Data Loggers & Slave Modules that connect to SDI-12 Sensors.

FEATURES

  • Sutron’s SDI-Link provides a way for an SDI-12 data recorder to read one or more SDI-12 sensors located up to 1 mile away using un-licensed band radios.
  • The SDI-Link is fully SDI-12 V1.3 compliant and will work with any compliant sensor and data recorder.
  • The extended range of up to 1 mile LOS (line of sight) allows the user to get data from sensors that previously would have required a separate data recorder or long, expensive cables.
  • Able to communicate using SDI-12 or RS-232 mode
  • The SDI-Link comes in a NEMA-4 rated enclosure with built-in antenna that easily mounts outdoors on a wall or pipe.
  • The SDI-Link comes in two basic models – a master (WSDI-M) that connects to the data recorder and a slave (WSDI-S) that connects to sensors.
  • The slave model of the SDI-Link includes a battery charger so all you need to add for a standalone, remote sensor is a battery and solar panel.
