Soil heat flux sensors may consist of several thermocouples whose measurements are averaged, a single thermopile, or a single thermopile with a film heater. These sensors measure the rate of energy transferred through a surface. Data regarding the amount of energy stored in soil as a function of time is used in energy-balance and Bowen-ratio flux systems.
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
