Description
The IP81 Explosion proof current
to pressure transducer produces
a pneumatic output that is directly
proportional to a current input
signal. A closed loop pressure
feedback control system provides
a highly accurate, stable air
pressure output for the operation
of actuated valves. The unit
can mount in any position and
is insensitive to vibration.
Its compact housing and easily
accessible ports and adjustments
make setup and installation
simple. An integral volume booster
provides high flow capacity,
which increases control speed
in critical applications.
This
compact I/P transducer delivers
reliable high performance for
the toughest applications in
the most hazardous environments.
The IP81 converts an electrical
current signal to a stable,
pneumatic output to actuate
valves. Its NEMA 4X (IP65) housing
is designed for both intrinsically
safe and explosion proof operation.
Advanced circuitry includes
electronic feedback control
for superior vibration protection
and highly accurate output.
With flow rates up to 12 SCFM
(20m /hr), the IP81 has the
muscle to drive large valves
and actuators. It is very economical
to operate, consuming only 0.05
SCFM (0.11m /hr), which is especially
important in natural gas applications.
Its small footprint can fit
into tight spots. An optional
mounting kit lets you mount
it directly on a valve, wall,
panel, or 2” pipe. And
since the IP81 is position insensitive,
it provides even more freedom
in mounting and connecting to
valves and instruments. Easy
access Zero and Span adjustments
make bench or field calibration
quick and easy.

For
operating versatility, you can
choose direct, reverse, and
split range modes. A piezoelectric
bimorph actuator and surface
mounted electronics are conveniently
mounted on a removable control
manifold that allows easy maintenance.
The IP81 can be out of the box
and up and running quickly.
Whether designing a new control
system or upgrading an old one,
the IP81 is the best unit for
the job. It is a great combination
of performance and value. contact
Action Instruments today and
one of our application specialists
will be happy to discuss your
needs.
The
IP8 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 control circuitry.
The feedback circuit compares
this signal to the input signal
and self corrects as necessary,
thus minimizing the effects
of vibration, position, temperature
and supply pressure. The current
signal flows to the piezo actuator
causing it to bend toward the
nozzle. This restricts the flow
of air through the nozzle and
creates back pressure in the
pilot pressure chamber. This
back pressure acts as a signal
pressure which in turn controls
the pressure at the output.
