Electro­Pneumatic
Transducer

he major issue with the design of electro-pneumatic
transducers is the balance between emissions and

T

uptime. If designed to minimize emissions, then the
device can be prone to plugging, especially if natural gas is
being used as the pneumatic supply.

The Fisher i2P-100 transducer is designed to meet
environmental concerns, but optimized to provide maximum
uptime. It features dual compartments with an “explosive-fluid
seal” to prevent natural gas from migrating to the electrical
conduit. Additional advantages offered by the i2P-100
transducer include corrosion resistance, tolerance to dirty
supply and vibration resistance.

These features give the i2P-100 transducer outstanding ability
to operate safer while improving uptime.

Installation

Each i2P-100 converts a millampere
input signal to a pneumatic signal
to operate a valve actuator,
damper drive or valve positioner.
It can be mounted directly to the
valve actuator case or to a
pipestand or surface.

Approved For Use With
Natural Gas

The i2P-100 transducer is ideal
when using natural gas as the
pneumatic supply, such as in gas
production facilities, compressor
stations and offshore platforms.

Corrosion Resistance

Converter module coils have a
corrosion resistant coating, and all
flexures are gold plated to provide
protection from hostile environments.
Dual compartment housing with an
“explosive-fluid seal” separates the
pneumatic and electronic components.

The features, shown below, give the i2P-100 transducer
outstanding ability to operate safer while improving uptime.

Plug-In Converter

The corrosion resistant, rugged
i2P-100 uses a modular design that
allows for fast replacement of the
converter module.

Vent and
Pipe-Away Vent Capability

When the i2P-100 transducer
exhausts, air is released through
the vent to the atmosphere. When
not exhausting, the vent closes to
prevent water from entering the
instrument. If you need to pipe away
natural gas, simply remove the vent
and screw a 0.25 inch NPT pipe into
the housing.

Relay Assembly

The i2P-100 transducer can produce
output volume up to 8.0 normal
m3/hr (5.0 scfm). Pneumatic tubing
connects to a 0.25 inch NPT female
connection for output pressure.

Replaceable Filter and
Removable Primary Orifice

Particles in pneumatic supply
usually clog nozzles in low-bleed
transducers. This is not so with the
i2P-100. Its 5-micron filter helps
prevent clogging of the orifice,
thereby minimizing the need for
maintenance. The primary orifice
is easy to remove for service to
promote a longer operating life. The
filter and orifice can be accessed
from outside the device, without the
need for a complete strip down and
without removing the cover on the
electronics compartment.
