Contact/ ma/ Wireless Application
(OP)
I have an application. I have a device that has an 4 to 20ma output, and a contact closure. I would like to be able to transmit these two signals to two different recievers. The receiver would be able to output the contact closure as well as the 4 to 20 ma signals.
One receiver would be located 1200ft from the transmitter and the other one 3600ft from the transmitter.
Any ideas if such a device exists?
Thanks.

There are wireless RS232 modems that can be purchased if you can get to a "data stream" situation. You could use this if your meters and sensor can be had in a serial data output format. Generally these are bidirectional point to point and you are really talking unidirectional point-to-many.

Wheels within wheels / In a spiral array
A pattern so grand / And complex
Time after time / We lose sight of the way
Our causes can't see / Their effects.
