5.2.3.2 FW05 Thermocouple
The FW05 is a Type E thermocouple with a 0.0127 mm (0.0005 in) diameter
). The thermocouple measures atmospheric temperature
fluctuations and may be used with the CSAT3B to directly calculate sensible
heat flux. Larger size fine-wire thermocouples, such as the FW1 and FW3,
which are more robust but have slower response times, may also be used with
the CSAT3B.
FIGURE 5-7. FW05 thermocouple
Users requiring fine-wire thermocouples for atmospheric
temperature measurements should consider their data logger
choice. The CR6 data logger is not optimal for taking fine-wire
thermocouple measurements. For help in choosing the best data
logger when fine-wire thermocouples are required, contact
Campbell Scientific.
5.2.3.3 FWC-L Cable
The FWC-L is a cable with connector that mates with the connector on a
FW05, FW1, or FW3 fine-wire thermocouple. The other end of the cable has
pigtail wires to wire to a pair of differential voltage channels on a data logger.
The –L denotes the length of cable in feet, which can be designated at the time
of ordering.
