When two dissimilar metals are joined at two junctions, and
these junctions are subjected to different temperatures, a
potential difference develops across these junctions. This
gives rise to flow of current between two junctions. (As
per Seebeck). Voltage Difference induced, V= Seebeck Const*
(Temp difference) between the two junctions.
This is because the two dissimilar metals behave
differently to the temperature difference, thereby inducing
current flow in the loop.

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 ?

In split range control, we will control 2 outputs with time interval. Eg :(with 4-20 ma signal, for 4-12 ma we are operating one control instrument like valve & for 12-20ma we are operating other control instrumet (other valve). If we get a signal of 15ma to first instrument (Valve 1), what will happened to the first valve, and if we get signal above 20 ma to 2 valve what will happened ?
