PFMB, Digital Air Flow Sensor, 2-Color Display, IP40, 5-2000 Lpm

PFMB, Digital Air Flow Sensor, 2-Color Display, IP40, 5-2000 Lpm

PFMB 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 4-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 cable connector type, and bracket mount.  Two outputs are available, including two switch signals, or a switch and analog signal.  PFMB is IP40 rated, and CE and RoHS compliant.

  • Flow range (lpm): 5-500, 10-1000, 20-2000
  • Port sizes (Rc, NPT, G): 1/2 or 3/4 (flow range dependent)
  • Rated pressure range (MPa): 0 to 0.8
  • Output options: NPN/PNP, 1-5V, 4-20mA
  • Accuracy: ±3% F.S.
  • Repeatability: ±1% F.S.
