Dwyer Series STRA

Features & Benefits

  • Low signal-to-noise ratio.
  • Honeycomb airflow straightening section with 1/2″ opening by 3″ depth.
  • Multiple total and static pressure sensing ports along the length of the element.
  • Factory mounted and pre-piped in a flanged duct section (casing).
  • ±2% accuracy throughout velocity ranges of 100 fpm and over.
  • Standard construction includes galvanized casing and 6063-T5 anodized aluminum flow sensors.
  • Standard airflow stations can be operated (in air) continuously in temperatures up to 350°F or intermittently in temperatures up to 400°F.
  • All airflow stations can be operated in humidity ranges of 0 to 100%.
  • Standard airflow stations have good salt air resistance and are suitable for most HVAC applications.
  • Great for use where turbulent conditions exist
