Overview

Use of a thermo-module as a soil heat flux sensor

Soil heat flux sensors, The first task was construction of the soil heat flux sensors, The commercial thermo-module has two lead wires of approximately 10 cm, but they are too short for calibration and field experiment, The lead wires were soldered with extension wires of 7 m, the length which is determined based on the maximum distance between

HFP01 heat flux plate

The heat flux in W/m² is calculated by dividing the HFP01 output, a small voltage, by the sensitivity, The sensitivity is provided with HFP01 on its calibration certificate, A typical measurement location is equipped with 2 or more sensors, HFP01 is the world’s most popular sensor for heat flux measurement in the soil as well as through walls and building envelopes,

Soil Sensors

Heat flux, the amount of thermal energy that moves through an area of soil in a unit of time, is measured near the soil surface in three of the soil plots, All soil sensor measurements are made at 0,1 Hz, In addition, photosynthetically active radiation, net longwave radiation, relative humidity, and throughfall precipitation measurements are made in a subset of soil plots near the soil

HFP01-L: Soil Heat Flux Plate

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 surrounding medium, At least two sensors are required for each site to provide spatial averaging, Sites with heterogeneous media may require additional sensors,
