Could anyone give me the best option to log the motor amps of 3 units, and to log a pressure reading (3x compressors and constant pressure).
I wish to be able to download to a pc and produce graphs,data from a 7 day period, the logging intervals must be no more than 20 sec.
I am fully confused at all the options available.
I sp[oke with Pico tech, the envirmon starter kit seems ok to log the amps but how do I log the pressure ? Would I need to power any of the transducers or would this be auto fed from log box, I am expecting to use a 4-20ma transducer.... I think
