e.Handling the Hazardous Area Oxymitter DR
The Hazardous Area Oxymitter DR is designed for industrial applications. Treat each component of the system with care to avoid physical damage. Some probe components are made from ceramics, which are susceptible to shock when mishandled.
f.System Considerations
Prior to installing your Hazardous Area Oxymitter DR, make sure you have all the components necessary to make the system installation. Ensure all the components are properly integrated to make the system functional.
NOTE
Retain the packaging in which the Hazardous Area Oxymitter DR arrived from the factory in case any compo- nents are to be shipped to another
site. This packaging has been de- signed to protect the product.
After verifying that you have all the compo- nents, select mounting locations and deter- mine how each component will be placed in terms of available line voltage, ambient temperatures, environmental considera- tions, convenience, and serviceability. A typical system installation is illustrated in Figure
Instrument air for reference is optional for most applications. Ambient air will passively diffuse into the inside of the probe in suffi- cient quantity for an accurate measurement. Instrument air is required for applications where the ambient air at the probe location may not contain the typical 20.95% O2. An example would be an installation into a positive pressure flue gas duct which has many leaks into the surrounding air.
If the calibration gas bottles will be perma- nently connected, a blocking valve or check valve is required next to the calibration fit- tings on the termination housing.
