D6F-PH5050AD3

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)

RoHS Compliant

D6F-PH MEMS Differential pressure Sensor

Characteristics/Performance

Note: 1. At standard atmospheric pressure (1013.25 hPa)

Note: 2. Dry gas must not contain large particles, e.g., dust, oil, or mist.

Note: 3. Type D6F-PH is based on thermal flow principle. Air flow is needed to measure the differential pressure.

Typical characteristic of air flow by differential pressure is below.

Note: 4. The zero point tolerance and span tolerance are independent uncertainties and add according to the principles of error propagation.

Note: 5. With no condensation or icing.

Note: 6. Please call us about functions, such as fault detection, temperature check, Vdd check, threshold value setup.
