PROCESS DEVICE WITH SAMPLING SKEW
First Claim
1. An industrial process device for monitoring or controlling an industrial process, comprising:
- a first input configured to receive a first plurality of samples related to a first process variable;
a second input configured to receive a second plurality of samples related to a second process variable;
compensation circuitry configured to compensate for a time difference between the first plurality of samples and the second plurality of samples and provide a compensated output related to both process variables.

Abstract
An industrial process device for monitoring or controlling an industrial process includes a first input configured to receive a first plurality of samples related to a first process variable and a second input configured to receive a second plurality of samples related to a second process variable. Compensation circuitry is configured to compensate for a time difference between the first plurality of samples and the second plurality of samples and provide a compensated output related to at least one of the first and second process variables. The compensated output can comprise, or can be used to calculate a third process variable. The third process variable can be used to monitor or control the industrial process.

14. A method for use in an industrial process device for compensating for time difference between two process variables comprising:
-
receiving a first plurality of samples related to a first process variable; receiving a second plurality of samples related to a second process variable, wherein there is a time differential between the samples of the first and second process variables; compensating for the time difference between the first plurality of samples and the second plurality of samples; providing an output related to a third process variable as a function of a compensated value of first process variable and the second process variable. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
