Absolute pressure sensor
ABSOLUTE PRESSURE SENSOR REFERENCE CHART
| Power supply, pin 3 | V | 5 |
| Ground, pin 2 | ||
| Voltage on | Pin 4 | |
| 25 kPa (-0.75 bar) | V | approx. 0.5 |
| 50 kPa (-0.50 bar) | V | approx. 1.0 |
| 75 kPa (-0.25 bar) | V | approx. 1.5 |
| 100 kPa (±0 bar) | V | approx. 2.0 |
| 125 kPa (0.25 bar) | V | approx. 2.5 |
| 150 kPa (0.50 bar) | V | approx. 3.0 |
| 175 kPa (0.75 bar) | V | approx. 3.5 |
| 200 kPa (1.00 bar) | V | approx. 4.0 |
Pressure given in kPa is absolute pressure, i.e. 100 kPa corresponds to atmospheric pressure at sea level.
When checking pressure sensor with pressure/vacuum pump, a somewhat lower voltage may be obtained when measuring at high altitudes.
