One FW05 can be operated per IRGASON, but it is recommended to have three spares, as they break easily. The FW05 is a 0.0005 in. diameter, type E thermocouple mounted on a stainless-steel bayonet. The FW/ENC carrying case is required.
An FWC-L Connector Cable is required for the FW05. An extra four feet should be ordered, as this length of cable should be bundled inside the enclosure to minimize heat conduction on the terminal strips. The remaining cable length should be long enough to travel up the mast, across the crossarm, and to the IRGASON.
The 10080 Thermocouple Cover is placed over the Omega-brand thermocouple connectors and is used to mount the connectors to the side of the CSAT3 or to the 30217 mounting bracket of the IRGASON. It also minimizes temperature gradients across the connectors.
