A source of instrument air is optional at the oxygen probe for reference air
use. Since the unit is equipped with an in place calibration feature, provisions
can be made to permanently connect calibration gas bottles to the oxygen
probe.
If the calibration gas bottles will be permanently connected, a check valve is
required next to the calibration fittings on the integral electronics.
This check valve is to prevent breathing of the calibration gas line and
subsequent flue gas condensation and corrosion. The check valve is in
addition to the stop valve in the calibration gas kit.
NOTE:
The electronics is rated Type 4X (IP65) and is capable of operation at
temperatures up to 65°C (149°F).
Retain the packaging in which the Rosemount Two-Wire In-Situ Oxygen
Analyzer arrived from the factory in case any components are to be shipped
to another site. This packaging has been designed to protect the product.
