Abstract
A method for facilitating field replacement of sensors is presented. The replacement sensor's transfer function need only be measured, not adjusted, and the signal-processing unit's transfer function need only be adjusted, but not measured, to achieve simple field-replacement of sensors. With this method simple calculations and adjustments, typically expedited by means of a computer program, can be made in the field when sensor replacement is required. By way of the presently disclosed method sensor cost and size are not increased since no normalization techniques or components are required.
