The thermocouple connects to the data logger via the FWC cable. One differential analog input per sensor is required.
A reference temperature measurement is required. Options for measuring the reference temperature include:
The FW/ENC Carrying Case is required to ship our FW05 thermocouples. It holds up to four thermocouples. Thermocouples returned to Campbell Scientific for repair without this case will be shipped to the customer in a new case and the account charged accordingly.

Measuring the thermocouple with an accuracy of 0.01°C is difficult, if not impossible, because of polynomial errors, voltage errors, and potential temperature gradients across the data logger terminal strips.
Most Campbell Scientific data loggers can measure a thermocouple without any external signal conditioning. Therefore, a dedicated module is not required.
No. The fine-wire thermocouples were designed to measure ambient air temperature.
The FW05 has a frequency response that is adequate for the eddy-covariance flux application.
Sensible heat flux is defined as the covariance of vertical wind and temperature fluctuations, measured with fast-response sensors. For more information, refer to a micrometeorology textbook.
