should be ordered to connect the CSAT3H heater controller box to the other data acquisition
system. One end of the cable is a 3-pin IP67 military connector that connects to the controller
box; the other end is a pigtail with brown, white, and black wires that connects to the computer.
This cable comes at a set length of 15 ft.
CSAT3H heater controller power cable (CSAT3HCBL3-L)
A CSAT3HCBL3-L must be ordered to provide 24 VDC power to the CSAT3H heater controller
box. This cable is ordered to a specified length ranging from 1 to 30 feet. The cable has a 2-pin
IP67 military connector on the end that connects to the controller box, and a red- and black-
wired pigtail that connects to the 24 VDC power supply. Because the length of this cable has a
shorter maximum length than the CSAT3HCBL1-L, it is recommended that the CSAT3H controller
box be located close to the 24 VDC power supply.
4.2.3.2 FW05 thermocouple
The FW05 is a Type E thermocouple with a 0.0127 mm (0.0005 in) diameter (
(p. 11)).
The thermocouple measures atmospheric temperature fluctuations and may be used with the
CSAT3BH 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
CSAT3BH.

NOTE:
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.
4.2.3.3 FWC-L cable
The FWC-L is a cable with connector that is compatible 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
