Hazardous Area Oxygen System for High Temperatures
The EXGP is a high temperature zirconia oxygen probe and interface unit used with the 4680 Series instrument. It is certified for use in petrochemical plants, refineries, chemical plants and Zone 1 hazardous areas. The EXGP Probe (process temperatures 600° to 1400°C) comprises a ceramic detector housed in a protective sheath. A thermocouple is fitted within the probe to enable the process temperature to be monitored and provide automatic temperature compensation. The sheath material may be either aluminous porcelain (recommended for oxidizing atmospheres) or Incoloy 800 (recommended for reducing atmospheres) for use at maximum temperatures of 1250°C (2282°F) and 1000°C (1832°F), respectively. Special sheaths are available for use up to 1400°C (2552°F).
