PF2A3, Digital Flow Monitor, 1-Color Display, IP40, for PF2A5 Sensors
PF2A3 is a monitor with display for the PF2A5 remote flow sensors. The sensor and monitor can be located up to 3m apart using PF2A5's optional cable. The red 3-digit LED display can show instantaneous or accumulated flow. 2 NPN or PNP switch outputs are included, with an LED indicator for each, located below the display. Units can be switched between L/min or CFM (flow), and L or ft³ (accumulation). A key lockout function can prevent accidental setting changes during operation. A panel mount adapter is standard. PF2A3 is IP40 rated, and CE and RoHS compliant.
- Flow ranges (lpm): 1-10, 5-50, 10-100, 20-200, 50-500 (selectable from PF2A5 ranges)
- Power supply voltage: 12-24 VDC
- Switch output modes: Hysteresis, window comparator, accumulation set point, accumulation pulse
- Accumulated flow range: 999,999 L
- Accuracy: ±5% F.S.
- Repeatablility: ±1% F.S.
