Description
The IP71 transducer converts
a current signal to a proportional
pneumatic output. Using closed-loop
pressure feedback circuitry,
it provides precise, stable
pressure outputs to final control
elements. Immunity to vibration
or mounting position, high toler-
ance to impure air, and low
air consumption make this unit
ideal for demanding applications.
The compact housing, accessible
ports and easy adjustments make
it perfect for constrained spaces.
An integral volume booster provides
high flow capacity, increasing
control speed in critical applications.

Applications
The bimorph piezo actuator encapsulated
in a protective skin provides
defense against humidity and
contaminants often found in
process operating environments.
The IP71 utilizes a nozzle to
control
a pilot pressure to an integral
volume booster. The resultant
output pressure is measured
by a pressure sensor which in
turn provides a feedback signal
to the circuitry. The feedback
circuit compares this signal
to the input signal and self
corrects as necessary, thus
minimizing the effects of variation
in vibration, position, temperature,
and supply pressure. The current
signal flows to the piezo actuator
causing the actuator to move
toward a nozzle. This restricts
the flow of air through the
nozzle and creates back pressure
in the nozzle which acts as
a pilot pressure to an integral
booster relay.
