Hi There,
I have a simple 4-20ma curcuit. Sensor - Cable - LCD display. I would like to remove the cable and use some type of wireless system to transmit the data from the sensor to the LCD. It must be dc powered - 1.5-9v at the sensor end and 1.5-18v at the LCD end. Range of about 30-50m. Does anyone have any ideas. I saw some of the phoenix stuff, but it looks to big and the voltage / current requirements are a worry.
If also at the sensor end there could be the abilty to switch on a relay from a signal generated at the LCD end, that would be great.
Thanks in advance.
Cheers, ben
