why 4-20 mA signal is preferred over a 0-10V signal
Answer Posted / satishpatel
generally in a transister some amount of voltage is
required for turning it on. this voltage is the cutin
voltage. up to this voltage the exists a nonlinerity in its
charecteristics. beyond this cutin voltage the char. of
transister is linear. this nonlinear region lies between 0-
4ma,beyond 4ma it linear. this is why 4-20 ma range is used.
