Differential Pressure: Module 1136_0

Post by jsmad »

I am trying to read the pressure from my 1136_0 pressure sensor using the code below (the second line converts the voltage ratio into "inches of H20").

getPressureVoltageRatio = channelPressureSensor.getVoltageRatio()
convertPressureInH2O = (20.073*getPressureVoltageRatio) - 10.037

However, the output gives me a non-zero number when there is no airflow. Is this normal? Do I need to "zero" the reading in the code and is there a native method for doing this or is the best way just to subtract the "zero airflow" output from my above formula?
