2.3.7.2 Sample gas exhaust
A sample gas exhaust port is provided for installation with a process oxygen sampling system. Gas must
be directed from the sample exhaust port to a suitable vent source that does not apply significant
backpressure on the sampling system. The unit can be installed in-line with any Neutronics Inc. process
sampling system.
Enclosure (chassis)
The chassis (Figure 5) is manufactured of specially coated stainless steel. It is designed to provide a
general level of protection against mechanical damage from the local environment. It is also an important
component of the electrostatic discharge (ESD) shielding design. Since the Model 7100E is a flush
mounted module, the portion of the instrument housed in the chassis will be located behind the control
panel or embedded within the customer equipment enclosure. The enclosure is general purpose (IP20)
and is not watertight.
