PF2A5, Digital Air Flow Sensor, Remote, IP65, 1-500 Lpm
PF2A5 is a digital flow sensor compatible with air and nitrogen. This is the remote version of PF2A7, without a display. The mounting bracket is integrated into the body, while the M12 lead wire is optional. An analog voltage or current output is available. PF2A is IP65 rated, and CE and RoHS compliant. Please consider the PFG digital flow monitor for displaying this sensor's outputs. Also compatible with the PF2A3 and PF2A20 monitors.
- 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 0.5, or-0.05 to 0.75 (flow range dependent)
- Output options: 1-5V or 4-20mA
- Accuracy: ±5% F.S.
- Repeatability: ±1% F.S.

Digital Flow Switch
For Air
Note 1) For digital flow switch with unit switching function. (Fixed SI unit [(l/min, or l, m
3
or m

x 10

)] will be set for switch type without the unit switching function.)
Note 2) Flow rate display can be switched between the basic condition of 0°C, 101.3 kPa and the standard condition (ANR) of 20°C, 101.3 kPa, and 65% RH.
Note 3) Without lead wire.
Note 4) Accumulated flow rate is reset when the power supply turns OFF.
Note 5) Switch output and accumulated pulse output can be selected during initial setting.
Note 6)
Window comparator mode — Since hysteresis will reach 3 digits, keep P_1 and P_2 or n_1 and n_2 apart by 7 digits or more. (In case of output OUT2, n_1, 2 to be n_3, 4 and P_1, 2 to be P_3, 4.)
Note 7) The flow switch conforms to the CE mark.
