Campbell Scientific Fine Wire Thermocouples - FW3, FW1, FW05
Typically used to measure atmospheric temperature gradients or fluctuations.
The small mass of the thermocouple is less susceptible to solar loading; therefore, a radiation shield is not required. One differential analog input per sensor is required.
Features
FW3 is 0.003" in diameter, FW1 is 0.001", FW05 is 0.0005"
Extremely small diameters virtually eliminate solar loading
Type E thermocouples - typical output is 60 µV/°C
Typically used to measure atmospheric temperature flux with research-grade accuracy
