Figure 7 - Attaching wire coil to binding posts
Once the coil is attached to the binding posts, note the %Carbon displayed on the CAT-100. The
% Carbon should be as close to 0.83 as possible, or within the range of .83 ±. 03. In order to
increase the %C, increase the Coil Factor. In order to decrease the %C, decrease the Coil
Factor.
Preparing the Insertion Rod with Steel Wire Coil
The wire coil is designed to be placed in the testing atmosphere with the use of a metal
insertion rod that can be purchased from SSi. The parts of the insertion rod, shown in Figure 8,
are as follows:
• Shaft. A long metal shaft supports the working end of the insertion rod (where the wire
coil is housed) and allows the rod to span the length of a typical furnace access conduit.
• Threaded port connector. The port connector is designed to attach to, and provide a tight
connection with, the access port on a furnace.
• Protective cage. The protective cage provides housing for the wire coil when the coil is
attached to the insertion rod.
• Rod screw. The rod screw, which screws into the shaft through the protective cage,
helps keep the protective cage in place on the insertion rod.
