Heat flux sensors measure the rate of energy transferred through a given surface. The sensors can be several thermocouples whose measurements are averaged, a thermopile, or a thermopile with a film heater.
The HFP01, manufactured by Hukseflux, measures soil heat flux, typically for energy-balance or Bowen-ratio flux systems. It outputs a voltage signal that is proportional to the heat flux of the s...read more
The TCAV-L typically provides the average temperature of the top 6 to 8 cm of soil for energy-balance in flux systems. It parallels four thermocouples together into one 24 AWG wire. Each member of a t...read more
