WARNING
Electrical shock
Failure to install covers and ground leads could result in serious injury or
death.
Install all protective covers and ground leads after installation.
1.1 Mechanical installation
Most combustion processes run only slightly negative or positive in pressure,
so that the probe flange is for mechanical mounting only. The probe is not
rated for high pressures. If this is a new installation, Emerson can supply a
weld plate for welding to the flue gas duct.
1.1.1 Install probe
Prerequisites
Ensure all components are available to install the probe.
Procedure
1. If using the optional ceramic diffusion element, the vee-deflector
must be correctly oriented. Before inserting the Rosemount 6888C
probe, check the direction of gas flow in the duct. Orient the vee-
deflector so the apex points upstream towards the flow.
2. If using the standard square weld plate or an optional flange
mounting plate, weld or bolt the plate onto the duct.
The through hole diameter in the stack or duct wall and refractory
material must be at least 2.5 in (64 mm).
3. Insert probe through the opening in the mounting flange and bolt
the unit to the flange.
