What is the difference between pneumatic and electro
pnematic positioner?
Answer Posted / jeetu chaudhary
The only difference between Pneumatic Positioner
and Electropneumatic Positioner is the
electropneumatic (i/p) converter unit in the
electropneumatic
positioner to convert the electric signal from the
controller into a
proportional pneumatic signal.
These positioners use a flapper-nozzle system, which
operates
according to the force-balance principle. They can be
applied
for both normal and split-range operation.
