Hi All - The project has a signal that would be stationary but the DAQ will move. Distance will be less than or equal to 1000 meters, and could be much less but nominally 500 m. I don't like wireless and prefer to use actual signal wire however that might not be an option. Can anyone recommend a cheap robust NEMA 4X wireless transmitter and receiver for a 4-20 mA signal appropriate for an industrial/agricultural site? Looking at Omega Engineering something like the zED-P Series or ZW-ED Series except I don't like the web server - I just want simple, easy to use, easy to support and troubleshoot. Is the 2.4 GHz IEEE 802.15.4 transmitter the best option for the price and distance or can someone recommend a different protocol/technology? Is 900 MHz better for longer distances like this? Outside the US, is 900 MHz a problem where 2.4 GHz is unregulated? Would you say the Wireless HART transmitter from Phoenix Contacts pn RAD-WHA-1/2NPT - 2900100 is the 'industry standard' and a good default option? Or any other thoughts/comments?
Thanks in advance.
