Is it possible to electrically isolate HART transmitters?

Yes, when using the HART D6C 52500, a 2-wire measuring transducer can be fed and operated by means of HART communication. The 4 - 20 mA measured value with the modulated HART signal is conveyed smoothly over the isolating distance; HART communication is bi-directional, i.e. it is transported in both directions across the electrical isolation.
