General Description
The DSA3200/3300-PTP series pressure acquisition
systems represent the next generation of multi-point
electronic pressure scanning. Model DSA3207/3307PTP Digital Sensor Array, incorporates 2 to 16 temperature compensated media isolated piezoresistive
pressure sensors.
All data acquisition, data conversion and communications tasks are handled by the integrated A/Dconverters and processor. This combination provides
easy setup, simple operation and long term reliability. The result is a network ready intelligent pressure
scanning module for “all media” service.
The microprocessor compensates for environmental
temperature changes and performs engineering unit
conversion. Pressure data outputs the data in either
ASCII or Binary format over the Ethernet network
TCP/IP or UDP. The DSA-PTP can be setup by theuser and all configuration variables can be set overthe same Ethernet connection.

Applications
The DSA3207/3307PTP Digital Sensor Array is a rugged design for use with turbine and diesel engine test
applications or any liquid measurement application.
It is ideal for industrial pressure measurement wherelong calibration intervals are required and temperatures can vary greatly. An optional heater kit is available for temperatures down to -20° C.

DSA3207PTP/Base with
8 ea. Sensor packs
DSA firmware allows for liquid head correction andonline rezeroing of the pressure sensors.
There are 3 configurations listed below available formeasuring liquids:• Gauge measurement (wet/dry)• Absolute measurement (wet)• Differential measurement (wet/wet)

DSA3207-PTP - Gauge & Absolute (wet/dry)
This model contains a stainless steel diaphragm
isolating the measurement side of each pressuretransducer from the media. The back side of thegauge transducer must be dry. This design also
contains a bleed valve per transducer for venting gas
bubbles from the input lines. These individual bleedvalves also allow for back filling the DSA input lines.

DSA3307-PTP - Differential (wet/wet)This model contains 2 to 16 single sensing element
pressure transducers that are
isolated from the media on both sides by a 316L
stainless steel diaphragm.
It is used in applications for measuring flow orwhen measuring high line low differential liquidmeasurements.

ISO 9001:2015 CERTIFIEDDSAModule
On-line Sensor Compensation
Calibration
Each DSA3207/3307-PTP piezoresistive pressure
sensor is isolated from the media to be measured
by a stainless steel diaphragm and body. This pressure sensor package is rugged and field replaceable.

Gauge & Absolute (wet/dry)
Model DSA3207-PTP contains a stainless steel diaphragm isolating only the measurement side of thepressure transducer, the backside must be dry. This
design also contains a bleed valve per sensor.

Differential (wet/wet)
Model DSA3307-PTP contains a single sensing
element pressure transducer that is isolated fromthe media on both sides by a 316L stainless steel
diaphragm. A shunt-purge valve is installed toprovide flow between the positive and negative
pressure inputs and allow gas bubbles to be purged
from the system.

The pressure sensors are factory calibrated overtheir full pressure and temperature ranges. The
calibration result data is stored in a 60 planepressure/temperature look-up table in memory. A
re-zero calibration can be performed on demand.
Each pressure sensor’s offset is then updated andsaved in flash memory.
As the sensor bridge temperature changes, the microprocessor selects the appropriate temperatureplane or interpolates between planes to correct thepressure reading. This on-line calibration correctsfor zero drift and liquid head pressure, thus assuring a long term 6 month accuracy.
Each pressure input channel is isolated and independent. Up to 8 pressure ranges can be incorporated into one module. In addition, each pressure
input channel can be a different fluid.

Each DSA-PTP module has a unique, factory set,MAC address. The IP address of the DSA-PTP
module is user configurable.

Communications
The DSA3207/3307-PTP module interfaces directly
to a host via Ethernet connection. Scanivalve’s free
configuration utility software for LabVIEW® Runtime
is designed to assist a user in establishing communications and configuring the DSA-PTP module.

ment Kit includes the Configuration Utility softwareand examples to assist a user in the setup of thesystem. An OPC driver is also available.

Additionally, a Software Development Kit is available
for users who want to write their own detailed dataacquisition program in LabVIEW®. This Develop-Specifications
