Therefore integration is simplified by avoiding complex analogue circuitry.

0.5 to 4.5V Pressure Sensor Output Example

for example a Ratiometric pressure sensor with a range of 0-10Bar and the supply

Supply voltage = 5V

0Bar = 0.5V = 10%

10Bar=4.5V =90%

Pressure Range

• 1-300 Bar
• Custom ranges and units available
