Description
Technical field
The invention belongs to probe technologies field, particularly relate to the making method of the TDS probe of a kind of band temperature detecting function.
Background technology
Total dissolved solid (TDS, TotalDissolvedSolids) refers to the total amount of the solid being dissolved in the water, and unit of measure is partspermillions or mg/Lmilligram/Liter, and physical significance is be dissolved with how many milligrams of total dissolved solids in 1 premium on currency. Popular says, TDS value represents solute foreign matter content in water, and TDS value is more big, illustrates that the foreign matter content in water is big, water quality inferiority; Otherwise, TDS value is more little, and foreign matter content is little, and water quality is good.
At present, the application of TDS sensing probe is very wide, but traditional TDS induction probe is all the induction of simple direct type, there is certain defect: 1) the TDS detection probe profile in market is various, installs inconvenience; 2) there is difference because market water temperature uses, often have temperature contrast, but TDS water quality detection can be existed very big-difference by temperature contrast, situation detection drift occurring or surveying by mistake.
Based on this, for solving the problems of the technologies described above, need now the making method providing the TDS of a kind of band temperature detecting function to pop one's head in badly to produce TDS probe.
Summary of the invention
It is an object of the invention to: for the deficiencies in the prior art, and the making method that the TDS providing a kind of band temperature detecting function pops one's head in, the TDS probe made by this making method can gather TDS and temperature value simultaneously, then carries out analyzing compensation, thus improves the accurate degree of detection water quality.
For achieving the above object, the present invention adopts following technical scheme:
A making method for the TDS probe of band temperature detecting function, comprises the steps:
A, getting out draw point, by the rounding polishing of draw point two ends, centre carries out annular knurl process, is then inserted by draw point and molds mould in draw point in mould;
B, get out thermistor, thermistor is filled with adhesive curing in draw point on mould;
C, getting out wire rod and junctor, described draw point and described thermistor are all electrically connected with junctor by described wire rod;
The junction of D, described draw point, described thermistor and described wire rod is by the thermal shrinkable sleeve seal of tube;
E, get out shell, shell is sheathed on described draw point and described thermistor.
As a modification of the present invention, described draw point adopts titanium or titanium alloy material.
As a modification of the present invention, described thermistor is arranged with iron Buddhist actor playing a supporting role pipe.
As a modification of the present invention, the shell in step e is single shaping by injection mold so that outer casing forming rear casing circular arc face does not have spue line.
As a modification of the present invention, shell and thermistor in step e are tightly connected by the mode of shaping filling or epoxy resin filling.
As a modification of the present invention, the wire rod in step C is first welded on draw point, and then welds with thermistor pin.
As a modification of the present invention, in the draw point in steps A, the front end of mould is provided with venting hole.
The useful effect of the present invention is: the TDS of the band temperature detecting function produced by aforesaid method is popped one's head in when test analysis, it is possible to gather TDS and temperature value simultaneously, then carries out analyzing compensation, thus improves the accurate degree of detection water quality.
Accompanying drawing explanation
Fig. 1 is the structural representation that the method for the present invention makes TDS probe.
Fig. 2 is the sectional view that the method for the present invention makes TDS probe.
Embodiment
Below in conjunction with embodiment and Figure of description, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
As shown in Figure 1 and 2, the making method of the TDS probe of a kind of band temperature detecting function, comprises the steps:
A, getting out draw point 1, by the rounding polishing of draw point 1 two ends, centre carries out annular knurl process, is then inserted by draw point 1 and molds mould 2 in draw point in mould;
B, get out thermistor 3, thermistor 3 is filled with adhesive curing in draw point on mould 2, after fixing, can guarantee that thermistor 3 vitreum is not damaged;
C, getting out wire rod 4 and junctor 5, draw point 1 and thermistor 3 are all electrically connected with junctor 5 by wire rod 4;
D, draw point 1, thermistor 3 are sealed by pyrocondensation sleeve pipe 6 with the junction of wire rod 4;
E, get out shell 9, shell 9 is sheathed on draw point 1 and thermistor 3.
Above-mentioned steps A ensure that draw point 1 shaping fixing after not slidably, and draw point 1 spacing and draw point 1 length are ensured, size is accurate.
Preferably, draw point 1 adopts titanium or titanium alloy material, can the detection data of efficiently and accurately, draw PPM value accurately, and then judge the purity of water. By experiment and market validation, titanium or titanium alloy material uses stable, and image data is accurate, avoids surveying situation by mistake, more accurately and safety.
Preferably, thermistor 3 being arranged with iron Buddhist actor playing a supporting role's pipe 8, iron Buddhist actor playing a supporting role's pipe 8 has excellent chemical stability, erosion resistance, stopping property, height lubricate the not feature such as viscosity, electrical insulating property and good anti-ageingization endurance.
