A pressure measurement system uses a sensor that converts pressure into voltage according to the transfer function Vp = 0.5 √p. This voltage is then converted into a standard current range is then converted into a standard current range as used in process industries. As the pressure varies from 0 to 100 psi, the current varies. The correct transfer equation which coverts voltage to current is
1
\({V_p} = \sqrt {\frac{5}{3}\left( {I - 5} \right)} \)
2
\({V_p} = \frac{5}{4}\sqrt {\left( {I - 4} \right)} \)
3
\({V_p} = \frac{5}{3}\sqrt {\left( {I - 5} \right)} \)
4
\({V_p} = \sqrt {\frac{5}{4}\left( {I - 4} \right)} \)
