SECTION 2: INTRODUCTION
General Description
The Digital Sensor Array (DSA) is a stand-alone electronic
pressure scanner which can accept up to 16 pneumac
inputs. The module is specically designed for use in
applicaons where long calibraon intervals, simple
operaon, and high accuracy pressure measurements are
required. Each DSA incorporates 16 discrete, temperature
compensated, piezoresisve pressure sensors, a 24-bit
Analog-to-Digital converter and RTD per sensor, and a
microprocessor. Each pressure sensor is characterized
over pressure and temperature. This informaon is stored
in EEPROM memory and enables the module to directly
output temperature corrected pressure data in engineering
units.
The sensors within each DSA5000 series module are
arranged in groups of eight (8). Each block of eight (8) sen-
sors has its own calibraon valve. This calibraon valve has
four (4) modes of operaon and allows the DSA module to
perform measurement, calibraon, and purge funcons.
The four (4) modes are:
• Measurement
• Calibrate
• Isolate
• Purge
The calibraon valve is operated using an externally sup-
plied control pressure and three (3) normally closed,
internal solenoids which are controlled digitally in the DSA
soware. A single control pressure source of 90-120 psi
control pressure is required to properly operate the inter-
nal valves. The DSA calibraon valve ulizes “Normally Px”
valve logic where the valves default to measurement mode
when no control pressures are applied or when all integral
solenoids are o (closed).
Module Overview
The DSA5000 is a highly customizable 16 channel pressure
scanner that can be customized to t and adhere to many
dierent applicaons and requirements. All pneumac and
hardware conguraons will operate using the same so-
ware commands, and oer temperature corrected pressure
data output directly in engineering units.
The DSA5000 base is an aluminum, splash resistant enclo-
sure that provides electronic connecons and open-thread
pneumac connecons. The DSA can be congured in any
of the following pneumac conguraons:
• Standard or Common Dierenal, 16Px
• Dual Range, Standard Dierenal, 16DR
• True Dierenal, 8DPx
• Individual Reference, 16IR
• Dual Range, True Dierenal, 8DDR
• Absolute, 16APx
• Dual Range Absolute , 16ADR
All DSA modules will have isolated channel inputs for each
transducer installed. Most pneumac conguraons will
also include pneumac connecons (when applicable) for:
• Calibraon port, CAL
• Reference port, REF
• Purge Supply port, PRG
• Control Supply port, CTL Supply
Each DSA is installed with three (3) internal pneumac sole-
noids. These solenoids orchestrate the applicaon of the
control pressure supply, which can place the DSA into one
(1) of the four (4) modes. These solenoids are controlled
digitally from the DSA’s internal soware using soware
commands.
The pneumac inputs on the DSA5000 base model are
5/16”x24 female thread matching the SAE J1926-1 stan-
dard. The SAE J1926-1 is equivalent to ISO 11926-1 for
5/16”x24 o-ring sealing, straight thread ngs. While
these threaded ngs are standard, Scanivalve allows the
user to select the pneumac terminaon of these ports
with a DSA5000 Fing Kit. These ng kits can be installed
into the female threaded ngs and can provide one of
the following terminaon opons:
• Bulged Stainless Steel Tubulaons
• Brass and Stainless Steel Compression Fings
• Scanivalve’s Quick-coupler 063 Fing
Individual ngs or ng kits can be purchased sepa-
rately to have an assortment of opons on hand for quick
changes or a variety of pneumac connecons per module.
As an opon, no ngs or ng kit can be supplied with
a DSA to allow a user to install their own ngs using the
5/16”x24 female threads.
In addion to the dierent pneumac input opons,
DSA5000 modules can be congured with a Quick-Dis-
connect (QD) input header. This QD input header opon
creates a removable header for all pressure inputs chan-
nels 1 through 16. This allows all plumbing to the Px input
measurement ports to be disconnected at one me and
swapped with another module or header. This is ideal for
pre-plumbing models or test arcles without the DSA5000

present, or for changing modules without having to change
plumbing.
For pressure measurement applicaons where the ambi-
ent temperature around the DSA is to extend below the
temperature compensated range of the DSA module, the
DSA can be equipped with internal heaters to regulate the
internal temperature. This provides measurement stability
when the module is subjected to temperatures below 0°C
in ight test, wind turbines, or other sub-zero applicaons.
For pressure measurement applicaons where a high shock
or vibraon environment is a consideraon, the DSA5000
can be equipped with a Shock Mount Kit. The shock mount
kit can be removed or installed in the eld. This shock
mount’s base plate matches the footprint and mounng
layout of the legacy DSA3218. This makes the shock mount
a great opon if replacing legacy DSA3218s in the eld.
DSA5000 Pneumatic Configurations
The DSA5000 is available in 7 basic pneumac congura-
ons.
DSA5000 Standard 16Px
The DSA5000 Standard 16Px module provides 16 channels
of the same pressure range sensors. These 16 pressure
transducers are congured into two (2) groups of eight (8)
each. Each group of eight (8) transducers shares a common
calibraon valve and a common reference manifold. Single
range modules e the two reference manifolds together,
and the two calibraon valves together internally to pro-
vide the user with a single reference and a single calibraon
port. In this conguraon, all pressure values provided by
the sensors will be a ‘dierenal’ pressure value between
the Px Inputs and the common reference port. If the
common reference port is le open to atmospheric pres-
sure, the pressure values at the Px ports will be a ‘gauge’
measurement value. Figure 2.1 depicts the top panel of a
DSA5000 Standard 16Px.

DSA5000 Dual Range 16DR
The DSA5000 Dual Range 16DR module is available as a
dual pressure range module, oering eight (8) channels
of one pressure range and eight (8) channels of a dier-
ent pressure range. Like a standard DSA5000, each group
of eight (8) transducers share a common calibraon valve
and a common reference manifold. However, in dual range
modules the reference manifolds and the calibraon valves
are not ed together internally, and a separate reference
and calibraon port are provided on the top of the module
for each range. These ports are labeled CAL H and REF H
(high, channels 9-16), and CAL L and REF L (low, channels
1-8). Standard conguraon will place the lower pressure
range in the “low” side, channels 1-8. This can be altered at
the customers request. Figure 2.2 depicts the top panel of a
DSA5000 Dual Range 16DR module.

DSA5000 True Differential 8DPx
For true dierenal pressure measurement applicaons,
the DSA5000 can be congured with eight (8) true dier-
enal pressure transducers. They are arranged into two (2)
groups of four (4) transducers. Each transducer will have
a discrete input for the posive and negave side of the
transducer for a true dierenal pressure measurement
between two points. Like the DSA5000 Standard 16Px, each
group of transducers has a dedicated calibraon valve that
allows the input pressures to be blocked o during any
calibraon, including a zero oset calibraon (CALZ). In
calibrate mode, the reference ports will all be manifolded
to a single reference port. Figure 2.3 depicts the top panel
of a DSA5000 True Dierenal 8DPx module.

DSA5000 Individual Reference 16IR
For true dierenal pressure measurement applicaons
where the internal calibraon valve is not required to
control the reference pressure, the DSA5000 Individual
Reference 16IR provide two (2) discrete inputs for each
sensor (posive and negave), and 16 channels total (32
total inputs). A calibraon valve is provided for each group
of eight (8) sensors; however, unlike the DSA5000 Stan-
dard 16Px or True Dierenal 8DPx modules, a separate
reference port is provided for all sixteen (16) transducers
which are not controlled by the internal calibraon valves.
This means that a zero oset calibraon (CALZ) must be
performed with no pressure applied to the module, and
calibraons must be performed using an external manifold
to e all reference ports together. Figure 2.4 depicts the
top panel of a DSA5000 Individual Reference 16IR module.
NOTE: The Individual Reference 16IR cannot be congured
with the Quick-Disconnect (QD) header opon.

DSA5000 Dual Range, True Differential 8DDR
For true dierenal pressure measurement applicaons
where two pressure ranges are required, the DSA5000 Dual
Range, True Dierenal 8DDR provides two (2) ports for
each sensor, and 8 channels total (16 total inputs). They are
arranged into two (2) groups of four (4) transducers. Each
group can be of a dierent pressure range. A calibraon
valve is provided for each group of four (4) sensors. Similar
to the True Dierenal module, each group of transduc-
ers has a dedicated calibraon valve that allows the input
pressures to be blocked o during any calibraon, includ-
ing a zero oset calibraon (CALZ). In calibrate mode, the
reference (negave inputs) will be shorted to a single refer-
ence port per group. Like the Dual Range 8DR module, the
common ports are labeled CAL H and REF H (high, channels
5-8), and CAL L and REF L (low, channels 1-4). Standard con-
guraon will place the lower pressure range in the “low”
side, channels 1-8. This can be altered at the customers
request. Figure 2.5 depicts the top panel of a DSA5000 Dual
Range, True Dierenal 8DDR module.
NOTE: The Dual Range, True Dierenal 8DDR cannot be
congured with the Quick-Disconnect (QD) header.

DSA5000 Absolute 16APx
The DSA5000 Absolute 16APx module can be used for abso-
lute pressure measurement when equipped with absolute
pressure transducers. A calibraon valve is provided for
each group of eight (8) sensors (no reference port). All six-
teen (16) transducers are ed a single calibraon port. An
absolute module will provide pressure values as an abso-
lute value. Figure 2.6 depicts the top panel of a DSA5000
Absolute 16APx pressure module.

DSA5000 Dual Range Absolute 16ADR
The DSA5000 Dual Range Absolute 16ADR module can be
used for absolute pressure measurement, oering eight (8)
channels of one pressure range and eight (8) channels of a
dierent pressure range. Like a standard absolute DSA5000,
each group of eight (8) transducers share a common cali-
braon valve. However, in absolute dual range modules
the calibraon valves are not ed together internally, and
separate calibraon ports are provided on the top of the
module (no reference ports). They are labeled CAL H (high,
channels 9-16)and CAL L (low, channels 1-8). Standard con-
guraon will place the lower pressure range in the “low”
side, channels 1-8. This can be altered at the customers
request. Figure 2.7 depicts the top panel of a DSA5000 Dual
Range Absolute 16ADR pressure module.

DSA5000 Quick-Disconnect (QD) Header
DSA5000 modules can be ordered with the Quick-Discon-
nect (QD) header opon. When this opon is added, the
DSA5000’s input connecons will be on a single, removable
header that can be quickly separated from the DSA5000.
This allows for quick test setup changes or module swaps,
and minimizes both me and leak liabilies.
Figure 2.8 - Quick Disconnect (QD) Header
This opon works great for applicaons where:
• Plumbing from the test arcle or model must be
done prior to installaon of the pressure module.
Plumbing can be xed to the removable header, and
installed on the module when ready for tesng. This
allows the module to be stored in a safe locaon
when working with models or test arcles prior to
tesng.
• Module changes are required oen, whether
switching pressure ranges using the same inputs,
or when changing out modules for roune main-
tenance or calibraons. Modules sent to the
calibraon lab will typically not require the remov-
able input header which can stay xed to the test
arcle.
• Modules are shared between mulple facilies.
Plumbing from dierent test xtures can remain in
place with separate headers and modules can easily
be moved from one test staon to another. This also
benets facilies that use dierent input ngs.
For instance: 1/8” Compression ngs in Area A,
and 0.063” Tubulaons at Area B. Each header can
be equipped with the appropriate input ng kit.
The Px inputs on the header retain the same 5/16”x24
female threads, and each ng can be installed with any
variety of available ngs. The QD header opon is avail-
able for all pneumac conguraons except individual
reference (16IR) or true dierenal, dual range (8DDR)
modules. Figures 2.8 through 2.12 show the top view for
the QD header conguraon opons.
Separate QD input headers can be purchased separately to
supplement the one provided with a purchased module. A
blank QD header can be purchased to cover the input ports
on the DSA for storage, transport, and protecon. A blank-
ing adaptor can also be purchased to cap the QD header.
