Pressure Volts

25 kPa (-0.75 bar) approx. 0.48
50 kPa (-0.50 bar) approx. 0.95
100 kPa (±0 bar) approx. 1.9
125 kPa (0.25 bar) approx. 2.4
150 kPa (0.50 bar) approx. 2.8
175 kPa (0.75 bar) approx. 3.3

Pressure expressed in kPa refers to absolute pressure, i.e. 100 kPa corresponds to barometric pressure. When checking the pressure sensor using a pressure/vacuum pump, slightly lower voltages may be obtained it this is done at high altitudes, 5 V power supply.
