4-20ma wireless system
4-20ma wireless system
(OP)
Hi There,
I am looking for a small DC (1.5-12v)powered 4-20ma wireless system. I need to transmit the current signal from about 30m away from my DC powered display. It only needs to be a one way transmit. There is no computer involved in any way. It is a simple loop circuit that I would like to have the cables removed.
Any ideas chaps? I noticed another topic that mention soemthing aout the Phoenix wireless stuff, but it looks quite big and the ability to supply that power / current is a worry.
Thanks in advance.
Ben

2) Banner Engineering does analog in/analog out, with some mapping function in software.

Thanks for that. I have seen the Phoenix before, but it is too large and the power demands are too high. I loke the look of the Banner stuff, but I fear it may be the same.
Do you think I could converter 4-20ma to 0-1v or 0-5v and use a simple AM/FM TX/RX?
RE: 4-20ma wireless system
Banner's stuff runs on 10-30V dc, so 12Vdc is doable. They've also got battery packs that will run the transmit side. The receiver/gateway side should be line powered through a power supply.
