TP01 thermal properties sensor
Suggested use
A typical TP01 is part of a meteorological surface flux measurement system in which also wind, humidity, soil heat flux, soil temperatures at different depths and net radiation are measured. TP01 then serves to improve the estimate of the so-called storage term, which is used to model thermal heat transport in the soil. Measurements with TP01 are often combined with soil temperature profile measurements with sensor model STP01 and measurements with heat flux sensor model HFP01SC. Soil thermal properties change as a function of depth, in particular close to the soil surface. A typical measurement location is equipped with sensors at several depths. For good spatial averaging at least 2 sensors (> 5 m apart) should be installed at every depth. Hukseflux has equipped several testbeds in the electrical power industry, to monitor dryout, thermal runaway and thermal stability around mockup high-voltage power lines. Here the capability to perform a crude measurement of thermal diffusivity is an important feature, for modelling behavior under dynamic loads.
