GENERAL SPECIFICATIONS (Cont.)
Ease of Installation
Rotatable Topworks allows transmitter installation in
tight places, allows indicator to be positioned in
preferred direction, and eases field retrofit.
Two Conduit Entrances offer a choice of entry
positions for ease of installation and self-draining of
condensation regardless of mounting position and
topworks rotation.
Wiring Guides and Terminations provide ease of
wire entry and support, plenty of space to work and
store excess wire, and large, rugged screw terminals
for easy wire termination.
Environmental Protection
Transmitter is dusttight and weather resistant per
IEC IP66 and provides the environmental and
corrosion resistant protection of NEMA® Type 4X.
Electronics Housing and Housing Covers
Housing has two compartments to separate the
electronics from the field connections. The housing
and covers are made from low copper, die-cast
aluminum alloy with an epoxy finish, or from 316 ss.
Buna-N O-ring seals are used to seal the threaded
housing covers, housing neck, and terminal block.
Electronics Module
Printed wiring assemblies are conformally coated for
moisture and dust protection.
Electrical Terminations
Field wires enter through 1/2 NPT, PG 13.5, or M20
threaded entrances, as specified, on either side of
the electronics housing. Wires terminate under
screw terminals and washers on terminal block in
the field terminal compartment as shown in Figure 2.
Unused threaded field wire entrance is plugged to
insure moisture and RFI/EMI protection.

Figure 2. Field Terminal Connections
Three- or Four-Wire Connections
Transmitter is supplied with a 4-wire terminal block,
with the two negative terminals connected internally.
This means that the transmitter can be wired with
either three wires for wiring economy, or four wires
for maximum accuracy. For relatively short wiring
runs having low resistance, 3-wire connections can
be used to minimize wiring costs. However, a voltage
drop in the common lead carrying the power supply
current will cause an error in the 1 to 5 V dc signal.
For wiring runs with high resistance due to long
lengths (or other reasons), or for maximum
accuracy, a 4-wire connection may be used to
provide input-output isolation. With 4-wire
configurations, voltage drop in the power supply loop
will have minimal effect on measurement.

Optional External Zero Adjustment
An external pushbutton (Figure 3) mechanism is
isolated from the electronics compartment and
magnetically activates an internal reed switch
through the housing. This eliminates a potential leak
path for moisture or contaminants to get into the
electronics compartment. This zero adjustment can
be disabled by a configuration selection.
Optional Transmitter Mounting Bracket Sets
Numerous mounting bracket set options are offered
to accommodate almost any mounting configuration
required. See Dimensions-Nominal section.

GENERAL SPECIFICATIONS (Cont.)
Configuration and Calibration Data, and
Electronic Upgradeability
All factory characterization data, and user
configuration and calibration data are stored in the
sensor. This means that the electronics module may
be replaced, with one of like type, without the need
for reconfiguration or recalibration. Although module
replacement can affect accuracy up to 0.20% of
span, this error can be removed by an mA trim
without application of pressure.
Pressure Seals
Pressure seals are used with GPIDP Transmitters
when it is necessary to keep the transmitter
isolated from the process. A sealed system is used
for a process fluid that may be corrosive, viscous,
subject to temperature extremes, toxic, sanitary
or tend to collect and solidify.
Changing module types (from one protocol to
another) may require reconfiguration and
recalibration, as well as a different terminal block,
but all factory characterization data is retained.
Optional Custom Configuration (Option -C2)
For the transmitter to be custom configured by the
factory, the user must fill out a data form. If this
option is not selected, a standard default
configuration will be provided; for example:

GPIDP DIFFERENTIAL PRESSURE TRANSMITTERS (Figure 7)
Wide Rangeability
Five DP range sensors cover measurement
spans from 0.125 kPa to 21 MPa (0.5 inH2O to
3000 psi). This high turndown capability means that
most differential pressure applications are satisfied
with only these five ranges, simplifying your spare
transmitter and spare parts requirements.
Sensor Corrosion Protection
Choice of 316L ss, Co-Ni-Cr, Hastelloy C, Monel,
Gold-Plated 316L ss, and Tantalum materials. High
corrosion resistance of Co-Ni-Cr (TI 037-078)
means long service life without extra cost for exotic
materials. See TI 37-75b for process applicability
with Co-Ni-Cr and other wetted parts materials.

Process Connectors
Removable, gasketed process connectors allow a

For very corrosive chemical processes, 1/2 NPT
pvdf inserts are installed in the HI- and LO-side
316 ss covers when a traditional structure is used,
and used as the process connectors.
GPIDP Transmitter Structures
GP:50 offers these transmitters with a traditional
structure, and two low profile structures (LP1 and
LP2). A brief description follows.
TRADITIONAL STRUCTURE (FIGURE 8)
This structure uses a design where the process
connections are at 90° from the transmitter
centerline. Vertical and horizontal mounting are
provided for sensor cavity venting and draining.
LOW PROFILE STRUCTURE LP1 (FIGURE 9)
This structure provides process connections that
are in line with the transmitter centerline. It is
compact, and its light weight is ideal for direct
mounting to process piping or manifold. An
optional adapter plate (Options -P1 to -P8), shown
in Figure 10 with the LP2, is offered for mounting to
a Coplanar™ manifold. Sensor cavity venting and
draining is provided for both vertical and horizontal
installations.
LOW PROFILE STRUCTURE LP2 (FIGURE 10)
This structure, as with the LP1, is an in-line design
which can be direct or bracket mounted. It is used
for vertical installations, and can also be installed
on existing Coplanar manifolds using an adapter
plate (Options -P1 to -P8). Sensor cavity venting
and draining are also provided.
