PF2A7, Digital Air Flow Sensor, 2-Color Display, IP65, 1-500 Lpm

PF2A7 is a digital flow sensor compatible with air and nitrogen.  This is a legacy sensor, with refreshed feature sets offered by the newer PFMB and PFMC sensors.  The 3-digit LED display can show either instantaneous or accumulated flow.  The mounting bracket is integrated into the body, while the M12 lead wire is optional.  2 switch outputs are included, with an LED indicator for each located below the display.  PF2A is IP65 rated, and CE and RoHS compliant.

  • Flow ranges (lpm): 1-10, 5-50, 10-100, 20-200, 50-500
  • Port sizes (Rc, NPT, G): 1/8, 1/4, 3/8, 1/2 (flow range dependent)
  • Rated pressure range (MPa): -0.05 to 0.75
  • Output options: 2 PNP or NPN
  • Accuracy: ±5% F.S.
  • Repeatablility: ±1% F.S. or ±2% F.S. (flow range dependent)
