Network Cabling
One WET150 can be read with a WET150 Meter.
Multiple WET150s need a GP2 or other SDI-12 controller.
These Delta-T extension cables are terminated in M12 thumb-screw
connectors, male at one end, female at the other. Cables can be joined
together to extend runs, or can be connected via a T-piece to branch the
network and to connect to sensors. An advantage of the M12 connector
system is that it is quick and easy to build and modify SDI-12 networks.
Later if a network fails due to a faulty sensor or damaged cable, it is easy to
isolate sections by temporarily disconnecting whole network branches or
individual sensors to trace the fault.
M12 connectors on cables and the WET150 are waterproof to an IP
rating of IP68, but must be screwed together tightly to form this
waterproof seal. Failure to sufficiently tighten the thumb-screw / collar
may allow water ingress into the cable or sensor, leading to premature
failure which is not covered by warranty.
M12 plugs with screw connectors are available for adding other sensors to
the SDI-12 network.
