The 0-5V signal is a proportional signal based on the measurement of the selected output sensor. The voltage out spans the specified gas sensor concentration range.
In summary, 0V = 0ppm and 5V = designated range of sensor.
- With the 0-10ppm high concentration ozone sensor, 0V represents 0ppm ozone and 5V represents 10ppm.
- With the 0-0.5ppm low concentration sensor, 0V represents 0ppm ozone and 5V represents 0.500ppm ozone.
- The 0-0.15ppm ultra low sensor is a bit different. In this case, 0V represents 0ppm ozone and 1.5V represents 0.150ppm ozone.
The resolution of the analog signal is 8 bit.
