General Description

Applications

The DSA3200-PTP series pressure scanners are versatile,
all-in-one data acquisition systems. Each DSA3217/3218-PTP is built on a pressure sensor per measurement
channel architecture. Every pressure sensor is uniquely
calibrated over a wide temperature range. All dataacquisition, data conversion and communications tasks arehandled by the integrated A/D converters and processor.
This combination provides easy setup, simple operationand long term reliability.

The DSA3200-PTP series is available in two basic
configurations; the DSA3217-PTP and the DSA3218-PTP.
Both configurations offer the same functionality, but differ inpackaging and intended applications. The DSA3217-PTP
is enclosed in a stainless steel, splash resistant enclosure
intended for most laboratory, educational or other controlledenvironments. The DSA3218-PTP however, is enclosed in astainless steel, splash resistant, shock mounted enclosure
with Swagelok® fittings on all pneumatic connections. It
is intended for applications such as gas turbine testing,flight testing, industrial applications and other more ruggedenvironments.

In addition to the electronics, internal calibration valves areincluded to provide maximum functionality. The valves allow
for several logic states including measurement, isolate,calibrate and purge. In the calibration configuration, eithera known pressure can be applied for a span verification/correction, or the sensors can each be pneumaticallyshorted together allowing for a quick zero offset calibration.
This zero offset calibration feature, in conjunction withthe sensor’s natural stability and repeatability combine toprovide maximum long term accuracy.

Additionally, the DSA3218-PTP series offers an optional
heater or cooling kit, allowing the DSA-PTP to operate in amuch wider temperature range. This allows for year-round
operations in open test cells, close-coupled mounting togas turbine tests, elevated temperatures for Freon testingor any other environment where temperature extremes
will be seen or rapid temperature changes are expected.

Once processed, the DSA-PTP outputs the data in either
ASCII or Binary format over the Ethernet network TCP/IPor UDP. The DSA-PTP can be setup and all configuration
variables can be set over the same Ethernet connection.

Again, the DSA3200-PTP’s features and options offers
support for a wide range of applications and uses. The allin-one packaging makes configuration easy and operations
simple.

The result of the DSA-PTP’s careful design is a complete
package that makes multi-point pressure acquisition tasks
simple. The DSA-PTP’s functionality and flexibility make it
an excellent fit for a wide range of applications.

DSA3217/3218-PTP Features
Calibration ValveThe DSA3217/3218-PTP calibration valve is “Normally Px”
where no control pressures or a loss of control pressuredefaults the valve to the operate (measure) mode. 90
psi control pressure is required to switch the DSA-PTP
calibration valve into purge, calibrate or isolate mode.
Each of these states can be established during a test withmeasurement pressure applied. This flexibility allows theDSA-PTP to be calibrated online with either a zero or multipoint calibration.
An internal solenoid valve is utilized for performingquick zero calibrations without the use of a pressure calibrator. When actuated, the positive sideof the pressure sensor is pneumatically shorted to
the reference manifold, creating a zero differential.
The sensor offsets are then updated and saved in
EEPROM.

or interpolates between planes to correct the pressure
reading. This on-line temperature correction and quick zero
calibration corrects for inherent zero drift and temperaturesensitivity, thus assuring a long-term 6 month accuracy of±.05%FS (typical).

Configurations
DSA3217-PTP and DSA3218-PTP modules can beconfigured to specifically fit each unique application. Awide variety of pneumatic configurations as well as interface
options and environmental options are offered.
Pneumatic Configurations
Standard DSA-PTP modules come with the reference sideof all 16 transducers manifolded to a single reference port.
If the DSA is ordered as a dual-range unit, a reference isprovide for each range. As an option, the DSA can beconfigured with individual reference ports for all 16 channels.
For more flexibility when differential measurements arerequired, both DSA3217-PTP and DSA3218-PTP modules
can be offered in 8 channel “True Differential” configurations
which provides inputs and calibration valves on both sidesof each individual transducer.
Interface Options
DSA3218-PTP modules come standard with 1/8”
Swagelok® fittings. These can easily be substituted with1/16”, 1/4” or 6mm Swagelok® fittings.
Environmental Options
The DSA3218-PTP is designed for rugged environments,
but to supplement this capability the DSA3218-PTP can beoffered with a self-controlled internal heater, or input andexhaust ports for cooling. Depending on the environment,
DSA-PTP modules with heaters can be operated in ambient
temperatures down to -55°C. DSA-PTP modules withcooling kits can be operated to ambient temperatures of80°C, provided sufficient cooling air flow is provided.

As the sensed sensor bridge temperature changes, themicroprocessor selects the appropriate temperature plane▼Sensors - High Accuracy, Long Term Stability
Each DSA3217/3218-PTP silicon pressure sensor isthermally compensated and packaged in its own rugged
field-replaceable housing. The transducers are factory
calibrated over their full pressure and temperature ranges.
The resultant calibration data are stored in a 72 planepressure/temperature look-up table in EEPROM.
