I am a mechanical/hydraulics engineer with an application which may be
more suited to you guys' expertise. What I want to do is transmit a
signal from a remote (up to 5km) device through a long piece of steel
pipe. The remote device incorporates a sensor which produces a simple
signal (on/off) which I would like to detect remotely. Is this feasible
to transmit a sigal (electrical or sound) without any signal boosters
etc.? If this is in no way feasible I have other solutions but this
would make a real neat, simple and cheap solution. Your advice/help is
much appreciatd.
Acoustic transmission seems like a possibility, and you can do a
preliminary test with a hammer, a contact probe stethoscope (or just an
ear to the pipe) and a couple of cell phones. Where is the pipe located
anyway?
