Abstract
The invention relates to a soil thermal flux sensor for measuring soil energy balance and soil layer heat conductivity, including a body (1). An inner groove (5) for storing a thermopile (2) is arranged on the body (1). The outer lateral of the thermopile (2) is equipped with a cover plate (3). The thermopile (2) consists of two serial monomers. One end of the body (1) is equipped with a conductor (4). The body (1) is made of a material made from polytetrafluoroethylene with corrosion resistance and insect resistant performances. The thermopile arranged in the body comprises a plurality of serial monomers. The soil thermal flux sensor of the invention has the advantages of high measurement sensitivity, good stability and corrosion and insect resistance.
Description
Technical field
The present invention relates to a kind of meteorological measuring set, particularly a kind of and data acquisition unit is used, can accurately measures a kind of soil heat flux sensor of the energy equilibrium and the edaphic pyroconductivity of soil.
Background technology
Traditional disposable soil heat flux sensor because body is a rubber, is easy to be stung damage by ant, mouse and damage, because the internal electrical thermal reactor adopts winding mode, monomer electric heating heap two output voltage is not only made inconvenient, and poor stability, influenced measuring accuracy.Energy equilibrium and edaphic pyroconductivity confidence level to research soil are lower.
Summary of the invention
Task of the present invention is to provide a kind of and corrosion-resistantly, pest-resistant stings, easy to make, highly sensitive soil heat flux sensor.
The technical solution of soil heat flux sensor of the present invention is: body is made by corrosion-resistant, the pest-resistant polytetrafluoroethylmaterial material of stinging, the inside of body has the groove of placing thermoelectric pile, thermoelectric pile in the body is by two or more together monomer series-connected, and the cover plate press seal is on thermoelectric pile.
Body one end of soil heat flux sensor of the present invention has a hole of wearing lead, and seals admittedly with epoxy resin.
Beneficial effect of the present invention is: the energy equilibrium of measured soil and edaphic pyroconductivity highly sensitive, good stability, corrosion-resistant, pest-resistant stinging.
Description of drawings
Fig. 1 is the external structure synoptic diagram of soil heat flux sensor of the present invention.
Fig. 2 is the structural representation of 2 thermoelectric pile series connection of soil heat flux sensor of the present invention.
Embodiment
Fig. 1 is the external structure synoptic diagram of soil heat flux sensor of the present invention.Wherein, 1 is body, and 3 is cover plate, and 4 for drawing the hole of lead from thermoelectric pile.Fig. 2 is a soil heat flux sensor structural representation of the present invention, wherein in the body 1 inside groove 5 is set, and is used to deposit the thermoelectric pile 2 of two series connection, uses cover plate 3 press seal thermoelectric piles 2.Described body 1 is corrosion-resistant, pest-resistant polytetrafluoroethylmaterial material manufacturing of stinging.Soil heat flux sensor adopts thermoelectric pile to measure thermograde, and heat flux sensor receives heat radiation, and with the form output of voltage, voltage is proportional to thermoflux.
Thermoelectric pile 2 in the soil heat flux sensor of the present invention can for two monomer series-connected, also can use for monomer series-connected more than 2 together, can obtain higher sensor measurement sensitivity.Because thermoelectric pile 2 adopts winding mode, like this, voltage is exported from an end, has improved stability.
Claims (3)
1. soil heat flux sensor, comprise: body (1) is characterized in that: body (1) is gone up to be provided with and is deposited the inside groove (5) of thermoelectric pile (2), and the outside of thermoelectric pile (2) is provided with cover plate (3), described thermoelectric pile (2) is by 2 monomer series-connected compositions, and an end of body (1) has lead (4).
2. soil heat flux sensor according to claim 1 is characterized in that: body (1) adopts polytetrafluoroethylmaterial material to make.
