Abstract
The utility model discloses a platinum resistance temperature sensing element, it includes the platinum silk and with the lead-out wire that platinum silk two ends are connected, the platinum silk is in nonrust steel casing pipe, nonrust steel casing pipe's two ends are equipped with the head, the filler has still been put to nonrust steel casing pipe. The filler is magnesium oxide powder. Adopt above-mentioned technical scheme, the utility model discloses a platinum resistance temperature sensing element has eliminated the drawback that leads to by the skeleton owing to having left out the skeleton of making by materials such as pottery, glass, mica, consequently has that the shock resistance is good, temperature measurement scope receives wide advantage, makes the line footpath of platinum silk also eliminate certain restriction simultaneously.
Description
Technical field
The utility model relates to a kind of platinum resistance temp-sensing element, and a kind of element that is used for platinum resistance thermometer sensor, of more specifically saying so belongs to the temperature instrument Instrument technology field.
Background technology
Platinum resistance thermometer sensor, is to utilize the resistance value of platinum filament to change this ultimate principle design and making along with variation of temperature, resistance value R during by 0 ℃ (℃) size be divided into 10 ohm (calibration number for Pt10) and 100 ohm (calibration number be Pt100) etc., temperature-measuring range is-200-850 ℃.Platinum resistance thermometer sensor, has thermopair and two kinds of technological merits of thermistor concurrently and overcomes its shortcoming.
The platinum resistance temp-sensing element is the core of platinum resistance thermometer sensor,, existing platinum resistance temp-sensing element comprises temperature-sensing element skeleton, the platinum filament on the skeleton and the extension line that is connected with platinum filament two ends, and common temperature-sensing element skeleton is made by materials such as pottery, glass, micas.When making the platinum resistance temp-sensing element, around ceramic skeleton, the glass skeleton forms through complicated processes on the framves such as mica bone again by platinum filament.Therefore above-mentioned platinum resistance temp-sensing element exists the deficiency that shock resistance is poor, temperature-measuring range is restricted because its skeleton is made by materials such as pottery, glass, micas, simultaneously because platinum filament around the process technology limit of skeleton, makes the line footpath of platinum filament also be subjected to certain limitation.
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides that a kind of shock resistance is good, temperature-measuring range is wide, to the unrestricted platinum resistance temp-sensing element in line footpath of platinum filament.
For achieving the above object, the utility model is by the following technical solutions: a kind of platinum resistance temp-sensing element, it comprises platinum filament and the extension line that is connected with platinum filament two ends, described platinum filament is in the stainless steel sleeve pipe, two ends of described stainless steel sleeve pipe are provided with end socket, also are equipped with filling material in the described stainless steel sleeve pipe.
Described filling material is a magnesium oxide powder.
Adopt technique scheme, platinum resistance temp-sensing element of the present utility model is owing to omitted the skeleton of being made by materials such as pottery, glass, micas, eliminated the drawback that causes by skeleton, therefore have that shock resistance is good, temperature-measuring range is subjected to wide advantage, make the line footpath of platinum filament also eliminate certain restriction simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model platinum resistance temp-sensing element.
Among the figure: 1-platinum filament, 2-extension line, 3-stainless steel sleeve pipe, 4-end socket, 5-filling material.
Embodiment
As shown in Figure 1, platinum resistance temp-sensing element of the present utility model, it comprises platinum filament 1 and the extension line 2 that is connected with platinum filament two ends, described platinum filament 1 is in stainless steel sleeve pipe 3, two ends of described stainless steel sleeve pipe 3 are provided with end socket 4, and described extension line 2 passes one of them end socket 4.Also be equipped with filling material 5 in the described stainless steel sleeve pipe 3.Described filling material 5 is magnesium oxide powders.
