For an Instrumentation Engineer, is there any effect on
Instruments of safety zones like zone0, zone1, zone2.
As an instrumentation Engineer, what we have to consider or
remember while working in these areas.( zones 0,1,2).
generally transmitter power supply having some range(12v to
35v) but the out put(4-20 mA) must same for given input.If
we vary the power supply voltage then output mA also to be
change according to V=IR. Is there any voltage regulator
in the transmitter ?
