Overview
The FW3 is a Type E thermocouple with a 0.003 in. diameter. It measures atmospheric temperature gradients or fluctuations with research-grade accuracy. The FW3 is compatible with most Campbell Scientific data loggers, and it is often used in eddy-covariance systems.
Key Advantages
High accuracy for temperature-gradient and eddy-covariance applications
Technical Description
The FW3's small mass eliminates the need for a solar radiation shield. It consists of a type E thermocouple with a connector. The connector attaches the thermocouple to a data logger via the FWC-L cable.
Type E thermocouples are comprised of a chromel wire and a constantan wire joined at a measurement junction. A voltage potential is generated when the measurement end of the thermocouple is at a different temperature than the reference end of the thermocouple. The magnitude of the voltage potential is related to the temperature difference. Therefore, temperature can be determined by measuring the differences in potential created at the junction of the two wires.
Benefits
- High frequency response suitable for eddy-covariance applications
- Extremely small diameter virtually eliminates solar loading
- Well-suited for temperature gradient measurements
