Abstract
Systems, apparatuses and methods are disclosure for adjusting and/or modifying outputs of sensors based on deadband effects, where sensor adjustments may be based on a value, which may be a constant, such as an error value for the sensor, or a dynamic value. Differential pressure values measured from the output of sensors are compared to the value, and, in response to the comparison, the output of the sensor may be set substantially to zero if the measured differential pressure value is less than the value. Otherwise, the measured differential pressure values are passed through if they are is equal to or greater than the value. Additional techniques employing zero offsets, span adjustment and error scale adjustments are further disclosed.
