PFMB, Digital Air Flow Sensor, 2-Color Display, IP40, 2-200 Lpm

PFMB7201 is a digital flow sensor compatible with air and nitrogen.  Its thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage.  Dimensions and weight have been reduced dramatically compared to the legacy PF2A.  The 3-digit LED display can be red or green, changing when a set point is reached.  Either instantaneous or accumulated flow can be shown.  Options include inline or bottom piping entry, cable connector type, a manual flow adjustment valve, and panel or bracket mounts.  Two outputs are available, including two switch signals, or a switch and analog signal.  PFMB is IP40 rated, and C-UL-US, CE and RoHS compliant.

  • Flow range (lpm): 2-200
  • Port sizes: 1/4 (Rc, NPT, G) or ø8 one-touch fitting
  • Rated pressure range (MPa): 0 to 0.75
  • Output options: NPN/PNP, 1-5V, 4-20mA
