Overview
The FW05 is a Type E thermocouple with a 0.0005 in. diameter. It measures atmospheric temperature gradients or fluctuations with research-grade accuracy. The FW05 is compatible with most Campbell Scientific data loggers, and it is often used in eddy-covariance systems.
Key Advantages
High accuracy for eddy-covariance applications
Technical Description
The FW05 has the smallest diameter of our fine wire thermocouples. Because of this, it experiences the least amount of solar loading, but is also the most fragile. The thermocouple's small mass eliminates the need for a solar radiation shield.
The FW05 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.
A reference temperature measurement is required for thermocouple measurements. The temperature sensor built into many of our data loggers' wiring panel typically provides this measurement.
Benefits
- High frequency response suitable for eddy-covariance applications
- Extremely small diameter virtually eliminates solar loading
- Well-suited for measuring atmospheric temperature flux

Connector Cable for Fine-Wire Thermocouples
One FWC Connector Cable is required for each FW05 ordered. A 20-ft lead length is recommended for most applications.

Data Logger Considerations
The thermocouple connects to the data logger via the FWC cable. One differential analog input per sensor is required.
Reference Temperature Measurement
A reference temperature measurement is required. Options for measuring the reference temperature include:
- Thermistor built into the CR800, CR850, CR1000, CR3000, or CR5000 wiring panel
- PRT built into the wiring panel of the CR9050 or
- CR9051E input module for the CR9000X Measurement and Control Datalogger
- PRT built into the wiring panel of the CR723T input card for the CR7 Measurement and Control Datalogger
- CR10XTCR thermistor that connects to the CR10X wiring panel
Carrying Case
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.
