SDI-Link Wireless Bridge

    • 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.
    • Fully SDI-12 V1.3 Compliant
    • Full 2 way SDI-12 Communication
    • Always on ready for SDI-12 Communication
    • Up to a mile in range Line of Sight (LOS)
    • Multiple Slaves can connect to Master Node
    • Slave has built in Solar Regulator for stand alone use
    • Any project with long cable runs
    • Quick deployment gages
    • Bridge locations to locate DCP off of the bridge
    • Any project where you might have a large number of sensor concentrated in a small geographic area as with Rough River Project
    • As with Tom Bigbee, when the cost of running new cable and conduit is cost prohibitive
    • Any project where cable is not possible, such as over a body of water
