Introduction
This manual contains calibration and installation
information for the Moore Industries' Current-toPressure Transmitter (IPT). Along with a description
of the IPT, this manual contains information
regarding instrument air, filtration, applications and
recommendations. Related tables and illustrations
are provided for reference purposes.
This manual contains notes and cautions that must be
observed to prevent equipment damage or minor

Description
Individual IPTs consist of two parts: the transmitter
section and an interlocking pneumatic mounting
block, which snaps onto a rail. Units that are ordered
without a mounting block will clip onto an RIR or SIR
(rack or surface mounted header), which supplies air
to each unit using only one pneumatic supply pipe.
Both mounting blocks and supply headers contain
self-sealing valves. Therefore, the IPT can be
removed and replaced without disturbing the pneumatic connections or causing accidental venting of
the supply or output air.
Operation can be montiored or calibration performed
by using the electrical input and optional pneumatic
output test jacks. A red LED display, which indicates
the presence of an electrical input signal, is also
provided.
Table 1 contains the IPT equipment specifications,
including inputs, outputs, power requirements, and
performance characteristics.
Model Number. The IPT model number describes
the equipment type, functional characteristics, operating parameters, any options ordered, and housing. If
all other documentation is missing, this number is
used to identify equipment characteristics. The model
number for the IPT is located on a label on the side
of the unit.
The IPT is a compact 2-wire current-to-pressure
transmitter that converts a standard process current
signal to a pneumatic output. In its compact aluminum housing, the IPT snaps onto standard mounting
rails or optionally onto a header (RIR or SIR). Because of the extremely low dynamic mass of the
transducer element, the unit can be mounted in any
position and it is also very insensitive to shock and
vibration.
Serial Number. Moore Industries maintains a
complete history on every unit it sells and services.
This information is keyed to the serial number. When
service information is required on the IPT,
it is necessary to provide the factory with this number.
The serial number is located near the model number.

Instrument Air and
Filtration Information
NOTE
For optimum performance, the selection and
use of a good quality air filtration system is
essential. Most users find that it is much less
expensive and troublesome to design a system
that includes good air filtration than deal with
downtime and repairs later.
To assure the maximum service life of an IPT, two
things are important: a clean, dry air supply and a
closed-loop application. Good air quality involves
removing solids, oil and water from the air after
compression. The cleaner the air, the longer the
time before servicing is needed.
Oversizing elements avoids performance abberations
and reduces maintenance time. Redundancy should
be used where possible to avoid shutdown during
maintenance.
Solids: Random solid dirt, such as pipe scale and
rust, is rarely a problem in compressed air instrument
systems. A good filter removes these solids. However, if there is a desiccant dryer in the line, a highefficiency sub-micron filter is recommended to
remove the highly abrasive sub-micron particles
produced by the dryer. A high-efficiency filter is
desirable in any system, and is often a feature of
coalescing-type filters.
Liquid Oil: Liquid oil is the most common problem in
compressed air instrument systems. A coalescing
filter removes sub-micron liquid droplets from the air,
and is usually supplied with an automatic drain.
A coalescing filter works by trapping oil and water
droplets in a bed of microfibers. The droplets run
together at fiber cross-over points, form large liquid
drops, and are forced by air flow to a drain. A filter
system consisting of a general purpose first-stage
filter (about 5 micron) and a high-efficiency coalescing final filter is recommended to obtain contaminantfree air.
The exact location of the first-stage filter is not
important; it can be located just ahead of each final
filter, or a single first-stage filter can be located on a
main line to protect a number of final filters on branch
lines. Each final filter (coalescing) should be located
just ahead of each pressure regulator. In a new plant
installation, an oilless compressor may be used to
eliminate this problem.
Water: The amount of water in an air system de-
pends on temperature, pressure and the relative
humidity of the air. Therefore, this amount varies
widely with geographical location and weather.
Sufficient water must be removed to lower the dew
point of the air to a temperature below ambient. The
dew point (at line pressure) is expressed as the
temperature at which any moisture in the system
begins to condense.
Water may be removed using a number of techniques, including coalescing filters, refrigeration
dryers and desiccant dryers. In addition, a variety of
combinations and modular systems may be used for
special circumstances.
Care must be taken in the selection and location of
the filter, because cooling downstream of the filter can
cause more condensation of water. A coalescing
filter should be installed immediately upstream of the
pressure regulator. This type of filter removes most
of the water before the air enters the regulator. Air
leaving the regulator continues to dry due to the
expansion of the air.
For systems subjected to freezing temperatures, the
portion of the system that runs outdoors should have
a dryer installed. The dryer reduces the dew point
below the lowest expected outdoor temperature. A
desiccant dryer is used with a coalescing filter upstream to keep the desiccant dryer from being
damaged by oil or being overloaded with excessive
condensed water. Another high-efficiency coalescing
filter is recommended downstream of the dryer, to
remove the desiccant fines.

IPT
ISA Specifications: The Instrument Society of
America standard ISA-S73, 1975 (ANSI MC11.1-
1975) covers the air quality requirements for instrument grade air for use in pneumatic installations.
The dew point in outdoor installations must be at least
7.8°C (18°F) below the minimum local ambient
temperature. For indoor installations, the dew point
must be at least 7.8°C (18°F) below the minimum
interior temperature or 2°C (35°F), whichever is
greater. Although the ISA standard calls for a 35°F
dew point, this is often unnecessary indoors, and may
be unsatisfactory outdoors under freezing conditions.

Filters that exceed the ISA specification provide very
inexpensive protection. Although the ISA specification calls for particle size not to exceed 3 microns
and oil content not to exceed 1ppm, most filter
manufacturers supply a line of coalescing filters that
remove particles down to sub-micron sizes (often
0.01 micron) while also removing oil to below ISA
1ppm specification (often to 0.01ppm).
* All filters are based on maximum (full) air flow from the IPT.
** These filters do not have sight glasses on the bowls.

IPT
Application Information
The IPT
properly. In a closed loop, it is possible to measure
the controlled variable, to determine if a deviation
from the desired value exists, and to automatically
provide feedback for actuator loading pressure.
The IPT cannot operate in an open loop. An open
loop has inherent limitations that are not consistent
with precise control, such as: long term drift of the
loop dynamics, load fluctuations that require constant
adjustments of the actuator loading pressure, and
quality variations because of inconsistencies between
operating personnel. A controlled variable cannot be
directly measured in an open loop; this prevents
compensating adjustments to the system input. If an
IPT is installed in an open loop, it appears to drift due
to the lack of corrective feedback.
Recommendations
Any approach to providing good instrument air quality
should evaluate the worst case air flow and ambient
temperature of the location. This is required to
determine sizing of the air system elements. A
knowledge of yearly humidity cycles is also important
for this evaluation.
must be
installed in a closed loop to operate
The IPT requires periodic maintenance. The frequency of the service depends on the environment in
which the unit operates and the quality of the instrument air supplied. Service in the field is limited to
visual inspection and cleaning of the input nozzle filter
screen on the IPT and servicing of the compressed
instrument air filtration system. The unit may be
returned to the factory for complete
disassembly, cleaning, and servicing on a periodic
basis.
The use of coalescing filters with retention of 0.01
micron particles and droplets is recommended; they
remove all undesirable traces of oil and water droplets. Proper placement with respect to the
regulator(s) may eliminate the need for dryers, except
when coalescing filters are exposed to freezing
(keeping in mind that the dew point of the purified air
must be kept below worst case ambient).
Figures 1 and 2 illustrate typical non-redundant
systems with multiple branch lines. They both work in
any environment above freezing and differ only in the
placement of the general purpose first-stage filter.
Gages, valves, and differential pressure indicators
(for filter service monitoring) are not shown. It is
recommended that filters with integral service life
indicators or differential pressure indicators be used
to help ensure proper servicing, as well as redundancy to avoid shutdown during servicing.
CAUTION
Before placing IPTs in service, all pneu-
matic lines and mounting blocks or headers
(SIRs or RIRs) should be "blown down" to
purge contamination and condensation
deposited during piping and installation.
Also blow down lines to loads, since all
output air vents back through the IPT, and
there are never filters installed to trap these
contaminants (normally only present at
start-up). It is recommend this be done for
at least an hour, longer if there is evidence
of water or oil coming through.
Figures 1 and 2 differ in the method used to remove
water. The use of a desiccant type dryer (figure 2)
requires upstream filtration to prevent oil contamination of the dessicant, as well as downstream filtration,
to prevent desiccant fines from introducing new
contamination.
The service life of an IPT is directly proportional to the
cleanliness and dryness of its air supply. The small
additional cost of providing high-qulaity air ensures a
longer, more trouble-free service life for the unit.

IPT
Calibration
This section provides information necessary to adjust
and calibrate the IPT. Each unit is calibrated and
checked at the factory prior to shipment. Before
installation, every IPT should be checked by the user
for proper operation. Generally, these checks, which
are specified under Calibration Procedures, require
little or no adjustment.
Adjustments
The IPT has Zero and Span adjustments located on
the front panel of the unit. They are represented
symbolically on the front panel by the following
markings:
represents Zero
represents Span
The type of potentiometer used with these adjustments usually require 22 turns of the shaft to move
the wiper from one end of its range to the other. It is
equipped with a slip clutch at each end to prevent
damage if the adjustment is turned beyond the wiper
stop. Usually a slight change can be felt when the
clutch is at the end of a range (i.e., it is slipping).
However, if this change is not felt, either end can be
reached by turning the shaft 22 turns in the desired
direction. Turning these potentiometers clockwise
causes the related output to increase in quantity or
become more positive; while turning them counterclockwise causes the related output to decrease in
quantity or become more negative.
The Span potentiometer provides an adjustment
range of ±1 percent of full scale.
The Zero adjustment consists of a conical-tipped
machine screw that displaces a torque arm on the
flapper pivot. This controls the gap between the
flapper and the nozzle to establish the zero-air bleed
rate. The adjustment screw provides a control range
of ±3 percent of full scale.

IPT
Calibration Setup
Figure 3 is an illustration of a typical calibration setup,
including optional equipment. To check or calibrate
the IPT, connect the unit as shown in this illustration.
Refer to Calibration Procedures.
Calibration Procedure
There are two options shown in figure 3 for monitoring
the output of the IPT. The input current may be
measured by placing a milliammeter in series with the
input terminals as indicated by M1 or connected
across the electrical test jacks (+T and -T) as indicated by M2.
CAUTION
When measuring the input current using the
electrical test jacks, the milliammeter used
must have an internal impedance of less than
10ý. Even with 10ý internal impedance, the
readings can have a variation of as much as
±.02% of full scale.
1. For zero adjustment, connect an adjustable
current source to the electrical input terminal
block. Set the current input signal to zero percent
(e.g., 4mA for a 3-15 psig unit, 20mA for a 15-3
psig unit or 10mA for 3-15 psig unit with 10-50mA
input).
NOTE
Observe that the red LED indicator on the
front panel is illuminated at 4mA input
current and glows somewhat brighter with
increasing current.
2. Using an air pressure gauge to measure the input
air supply pressure, connect a filtered air supply
to the pneumatic supply port located on the
bottom or rear of the unit.
CAUTION
Coupler must be kept lubricated to prevent
damage to O-rings in test jacks. Teflon lubri-
cant is recommended. If grease is used, keep
out of air passage.
If the unit is not supplied with the output test
jacks, use an air pressure gauge to measure the
output air supply pressure (e.g., read 3 psig for a
3-15 psig unit or 15 psig for a 15-3 psig unit).
CAUTION
To avoid damaging their housings, use a
screwdriver with a head no wider than
0.1 inch (2.54mm) to adjust the Zero-
adjustment screw and Span potentiometer.
CAUTION
The Zero-adjustment screw must not be
backed out to the point where the slotted head
presses against the underside of the front
panel. It can put an excessive stress on the
transducer frame and may disengage the
screw from the flapper tension arm. If this
happens, the IPT must be returned to the
factory for realignment.
4. Any deviation in the output pressure can be
corrected by using the Zero-adjustment screw in
a range of ±3 percent.
5. For the Span adjustment, increase the input
signal to 100 percent (20mA or 50mA).
6. Any deviation in the output pressure (e.g., 15 psig
for a 3-15 psig unit or 3 psig for a 15-3 psig unit),
can be corrected by the Span potentiometer over
the range of ±1 percent.
7. Repeat steps 1 through 6 (as applicable) until no
further adjustments are required.
3. If the unit is supplied with the optional frontaccess pneumatic-output test jack, insert the
pneumatic coupler into the receptacle. This
avoids having to disturb any operating connections or fittings.

IPT
Installation
Installation of the IPT is divided into three phases:
mounting, electrical connections, and pneumatic
connections. In most cases, it is easier to mount the
IPT before completing the electrical and pneumatic
connections.
Mounting
Individual IPTs consist of two parts: the transmitter
and the mounting block. Units without a mounting
block snap onto a header. IPTs with a mounting
block are rail mounted. When mounting the IPT,
ensure that the unit is mounted in an area free of
dust, moisture, and corrosive elements. Figure 4
shows the mounting dimensions for both mounting
styles.
CAUTION
It is recommended that mounting blocks and
headers be purged of any debris prior to
mounting the IPT. Insert a small diameter,
blunt tip probe into the fitting and unseat the
ball-check valves for a few minutes with the
filtered instrument air supply in operation.
Rack- or surface-mounted IPTs should be ordered
with a Moore Industries' rack-mounted header (RIR)
or a surface-mounted header (SIR). This eliminates
the need for an interlocking mounting block and rail.
5, 10 or 15 units can be snapped onto one header,
allowing multiple units to receive supply air from one
supply pipe. To mount an IPT onto a header, push
the unit into place until the retaining lever snaps up
flush beneath the handle. To remove an IPT, press
down on the retaining lever and lift the unit out by the
handle.
NOTE
Check valves in the headers prevent the loss of
supply or output air during mounting or removal
of IPTs.
Rail-mounted IPTs must use a pneumatic mounting
block. Pneumatic mounting blocks are 1.39 inches
wide. Using a 0.17 inch wide gage between blocks
provides a uniform spacing in a minimum rail length.
Electrical Connections
There are two terminals on the IPT for connecting
input current. The connections can be front access
or rear access.
Both the front and rear access electrical terminals are
compression screw sockets that accept 22 to 14
AWG hookup wire. To complete these connections,
use a slotted screwdriver with a head approximately
0.125 inch (3mm) in width to secure the wire leads to
the IPT. The screws tighten down, which provides
electrical contact between the wire and the terminal.
Loosen each screw prior to inserting the wire being
terminated. Strip and then tin the end of each wire
with 60/40 solder. Then, while holding the uninsulated end of the wire in place, tighten the screw of the
corresponding terminal.
The Removable Terminal Block (RTB) option adds a
2-piece wire connector to the IPT. This alows the
input wiring to be unplugged without the use of tools,
while maintaining polarity. The plug has screw-clamp
connections and accepts 22 to 14 AWG wire. The
wire should be stripped 0.5 inch (12.7mm).
Pneumatic Connections
Supply air must be clean, dry instrument air. It is
recommended that all particles larger than 1 micron
be removed. Use of 1/4 inch tubing allows sufficient
air for one unit. When using RIR or SIR headers, up
to 30 IPTs may be run from a 3/4 inch NPT pipe
without degrading performance, provided the air
supply pressure is sufficient. Output tubing should be
1/4 inch, though larger tubing may be desirable for
exceptionally long runs. Purge the output tubing and
the controlled device before connecting to the IPT or
RIR/SIR.
CAUTION
Output air cycles back through the IPT.
Contamination in the output line or
controlled device may easily enter and
damage the IPT.
Page 14
Page 15
Page 16
Page 14
IPT
Maintenance
Because instrument air continuously flows through
IPT passageways, the air lines must be kept clean.
Depending on the purity of the air supply, the filter
and two internal orifices of the IPT assembly must be
cleaned at regular intervals to maintain specified
performance. The two orifices should be cleaned at
least once a year. Initial random checks can help
establish a satisfactory maintenance interval geared
to the user's air supply purity.
The supply air filter screen should be removed and
flushed with trichloroethance (TCE) and then air dried
before replacement.
1. Remove the IPT from the mounting block by
pressing down on the locking lever and pulling
straight out to disengage the pneumatic fittings.
2. To remove the supply air filter screen, first slide
the nozzle retainer clip to the right and then pull
the nozzle out of the main body.
3. Remove the filter screen and flush with TCE and
air dry before reinstalling.
4. Slide the nozzle back into the main body.
3. Without pulling the wires loose on the printed
circuit board attached to the front panel, slide out
the front panel.
4. Remove the screw on the bottom of the front
panel to free the printed circuit board.
5. Insert a blade screwdriver between the rear panel
and the IPT. Separate the rear panel from the
IPT.
6. Squeeze and slide back the clamp from the
tubing barb and pull the tubing from the tubing
barb (only on units with optional test jacks).
To access the orifices in the IPT, remove the bottom
mounting screw and the two screws at the rear of the
unit. The orifices are located in the subassembly.
See figure 6.
CAUTION
Use care not to damage the rubber
gaskets between the subassemblies.
Clean the orifices with a 0.004 - 0.005 inch diameter
steel wire. Push the wire through the hole. Refer to
figure 7 for orifice locations.
To clean its orifices, the IPT assembly must be
removed from the extruded aluminum case. To
remove the assembly, proceed as follows:
1. Remove the 6 screws securing the right side
cover and remove the cover.
2. Remove the bottom 4 screws securing the left
side cover and remove the cover. Turn the unit
over. The test point connector and the test point
jack are now free.

IPT
Troubleshooting
Many components of the IPT have been thermally
aged, tested, and selected using a computer-aided
design program. This usually makes field repair
unnecessary. It is therefore recommended that any
unit found to be performing below specifications be
returned to the factory in accordance with the instructions found on the back cover of this manual.
If a problem is suspected with the IPT, review the
following steps:
1. Make sure that all connections are clean and
tight.
2. Verify that bench instruments used to take
measurements have the proper range and
accuracy and are currently certified.
3. Check that the bleed-air port (located in a slot on
the left side panel) is not restricted.
4. Using a test jumper, connect one end to the metal
case and the other end to an "IN" terminal while
observing the output pressure. The output
pressure should not change.
5. If a change in the relationship between the input
and the output occurs, try to correct it by readjusting the Zero and Span controls.
6. If the response time lengthens or if the span
drops, this may indicate a blockage due to air
supply contamination. Clean the orifices and the
supply air filter as described in the Maintenance
section.
