  • Page 90: Filtering

    • Rectangular window The W-4510 transmitter has a sample rate of about one sample/second, but process variables generally change measurably on the order of minutes. Electrical and source noise occur on the order of seconds, so they can be filtered out with a low pass filter, leaving only the change in the process variable in the signal.

  • Page 91: Damping

    (in engineering units) between successive samples. This enables the W-4510 to respond immediately to large step changes while filtering the smaller variations in the signal caused by noise and normal process variations. To turn off the fast cutoff filter, set the value to zero.
