      How to Order

      A typical order number consists of the model number, pressure range, pressure unit, output and mounting connection.

      Model Type Output Signal FSO Pressure Range Calibration Pressure
      880 D = Differential or Gage* 4-20mA; Two-wire 0…..0.25″WC to 5″WC Customer designated exact FSO
      1…..>5″WC to 13″WC
      2…..>0.5PSI to 1PSI
      3…..>1PSI to 5PSI
      4…..>5PSI to 15PSI

      * With a gage application, one of the two ports is vented to atmosphere
