D6F-PH0025AD2
D6F-PH0025AMD2
Measurement conditions: Power supply voltage of 3.3 ±0.1 VDC, ambient tem-
perature of 25±5°C, and ambient humidity of 35% to 75%.
Differential pressure conversion formula: Dp = (Op - 1024) / 60000 × 250
Dp = Differential pressure, Op = Output

Measurement conditions: Power supply voltage of 3.3 ±0.1 VDC, ambient tem-
perature of 25±5°C, and ambient humidity of 35% to 75%.
Differential pressure conversion formula: Dp = (Op - 1024) / 60000 × 100 - 50
Dp = Differential pressure, Op = Output
D6F-PH5050AD3
D6F-PH5050AD4
D6F-PH5050AMD4
Measurement conditions: Power supply voltage of 3.3 ±0.1 VDC, ambient tem-
perature of 25±5°C, and ambient humidity of 35% to 75%.
Differential pressure conversion formula: Dp = (Op - 1024) / 60000 × 1000 - 500
Dp = Differential pressure, Op = Output
Note. Change of gas density affects the sensor output.
Change of atmospheric pressure is compensated by the following formula.
Dpeff = Dp × (Pstd / Pamb)
Dpeff: Effective differential pressure
Dp: Differential pressure of the sensor output
Pstd: Standard atmospheric pressure (1013.25 hPa)
Pamb: Actual ambient atmospheric pressure (hPa)
