  • Page 11: Chapter 1 System Overview

    SYSTEM OVERVIEW Sensor Operations Designed for fast response in a Continuous Emissions Monitoring System, the sensor provides continuous measurement of oxygen. A sample is directed from the process stream to the analyzer and then returned to the process. A portion of this gas rises past the oxygen measuring cell and returns to the primary loop.
  • Page 12 Sensor Basic Elements of the Sensor The WDG-V series analyzer consists of the following basic systems: The Plumbing  All inlet and outlet tubing (cell housing), the oxygen cell, the oxygen cell fit- ting. The Measuring System  The oxygen cell interconnecting wiring, and control electronics. The Temperature System ...

  • Page 14 The Oxygen Measuring Cell The sensing element itself is a closed-end tube or disk made from ceramic zir- conium oxide stabilized with an oxide of yttrium or calcium. Porous platinum coatings on the inside and outside serve as a catalyst and as electrodes. At high temperatures (generally above 1200°F/650°C), oxygen molecules coming in contact with the platinum electrodes near the sensor become ionic.
  • Page 15 where R and F are constants, T is absolute temperature, and O and O are the oxygen partial pressures on either side of the cell. For measuring oxygen in non-combustibles gases, the calibration of an analyzer is obtained from the formula: 20.9% E = A * T * Log AT = 45.78 at 650°C...
  • Page 16 Temperature Sensors There is one tightly controlled temperature zones in the WDG-V . The Oxygen Cell Temperature. Cell Temperature The Oxygen cell is controlled to 680°C. The cell temperature is measured by a dual, Type K thermocouple. A dual thermocouple is used for self check of the cell temperature.
