The model DSA3217 is versatile and one of our more popular
pressure scanners. It measures up to 16 gas pressures in many
applications. These applications include wind tunnel test for
buildings, aerospace and automotive aerodynamic tests, gas turbine
testing, compressor testing as well as other turbomachinery tests,
flow measurement across an orifice, wind turbine aerodynamic
validations, etc. Available options include a common
reference pressure or individual reference. For applications that
require a more rugged pressure scanner, Scanivalve's
DSA3218 may be a viable option.
The DSA3200 series pressure acquisition systems represent the
next generation of multi-point electronic pressure scanning. Model
DSA3217 Digital Sensor Array, incorporates 16 temperature
compensated piezoresistive pressure sensors with a pneumatic
calibration valve, RAM, 16 bit A/D converter, and a microprocessor
in a compact self contained module. The result is a network-ready
Ethernet pressure scanning module.
The microprocessor compensates for temperature changes and
performs engineering unit conversion. The microprocessor also
controls the actuation of an internal calibration valve to perform
on-line zero and multipoint calibrations. This on-line calibration
capability virtually eliminates sensor thermal errors with a long
term system accuracy of ±.05% FS (5 psi & up).
Pressure data are output in engineering units via Ethernet using
TCP/IP protocol.
Scanivalve offers an optional multi-range calibration. This
allows the DSA modules to have multiple pressure ranges. The
calibration valve and transducers are manifolded in groups of 8.
The user can specify up to 3 pressure ranges within that group of 8
as long as the ratio for all 3 full scale ranges doesnt exceed 3:1
from highest to lowest range.
