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 transducers 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.
