Next generation of Multi Point Pressure Scanning A new range of pressure systems are now available from Evolution Measurement Ltd, representing the next generation of multi-point electronic pressure scanning. The Scanivalve DSA3217-PTP Digital Pressure Scanner, 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, resulting in a network-ready Ethernet pressure scanning module. The DSA3200-PTP series microprocessor compensates for temperature changes and performs engineering unit conversion. It 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 is output in engineering units via Ethernet using TCP/IP, UDP or FTP protocol. Scanivalve offers an optional multi-range calibration, which 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 doesn't exceed 3:1 from highest to lowest range. The DSA3217-PTP is enclosed in a stainless steel, splash resistant enclosure intended for most laboratory, educational or other controlled environments. The DSA3218-PTP however, is enclosed in a stainless 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 rugged environments.
