Abstract
The utility model relates to a platinum resistance temperature measurement, which is characterized in that it cuts glass cane (1) to make cage, the platinum filament (2) is wound in slot, two sections of platina shred act as blaster fuse (4) of the resistance measurement and both ends of the platinum filament (2) are respectively welded with platinum blaster fuse (4) embedded in glass cane. The glass cane is sheathed with ceramic tube (3) and both ends of it are sealed with the blend of glass frit and ceramic powder (5), in addition, the gap between glass cane and annular tube is filled with alumina powder.
Description
The utility model relates to a kind of pinpoint accuracy and high strength resistance temperature measurement element, particularly relates to a kind of glass skeleton pottery armouring platinum resistor temperature measuring element.
The thermal resistance thermometric is to utilize the resistance value of metallic conductor to vary with temperature and the characteristic that changes is carried out thermometric.At present both at home and abroad the resistance temperature measurement element mainly contains following four kinds of structures: in (1) ceramic body, the platinum filament around formula, be about to be hung in the ceramic case in two holes or four holes behind the thin platinum filament coiling, the thermal resistance temperature element shock resistance of this structure is relatively poor, (2) ceramic skeleton, platinum filament externally-wound type, be about to thin platinum filament around the ceramic bar outside surface, be coated with glaze and form, the temperature element thermal stability of this structure is relatively poor.(3) glass skeleton, platinum filament externally-wound type are about to thin platinum filament on the glass bar of cutting, the covering glass bushing, and shortcoming is easily to break up, serviceability temperature is limited by glass softening point, generally can only use 500 ℃.(4) mica frame, platinum filament enwinding type, being about to platinum filament forms on the sheet mica sheet, its weak point is influenced by mica heat expansion or high-temperature outgassing, and serviceability temperature generally can only arrive 420 ℃, and is difficult for making miniaturized component.
Fundamental purpose of the present utility model provides a kind of being swift in response, and highly sensitive platinum resistor temperature measuring element particularly provides a kind of glass skeleton core, ceramic package armouring platinum resistor temperature measuring element.
The purpose of this utility model is achieved in that with the cutting glass bar makes skeleton, with diameter is that the platinum filament of 0.02～0.05mm is in groove, two sections platina silks are made the extension line of resistance measurement, with press seal after the welding of thin platinum filament winding in glass skeleton end, the glass skeleton is cleaned annealing, and after the fine tuning resistance, be encapsulated in the ceramic case, two ends glass ceramics micro mist sintering, ring-like slit oxygenation aluminium powder in skeleton and housing, to improve thermo-contact, reduce self-heating effect.
The utility model is because adopt the glass skeleton, ceramic package, so the intensity height, shock resistance is good, and is simple in structure, with low cost.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the synoptic diagram according to the ceramic platinum resistance temperature-sensing element that the utility model proposes.
Describe details in detail below in conjunction with Fig. 1 according to the concrete element that the utility model proposes.
The utility model ceramic platinum resistor temperature measuring element comprises glass bar (1), temperature-sensitive platinum filament (2), ceramic pipe (3), platinum lead-in wire (4), ceramic powder and glass dust potpourri (5) and alumina powder (6).
On glass bar (1), be wound with temperature-sensitive platinum filament (2), twine and adopt double wrap not have sensing method, temperature-sensitive platinum filament two ends respectively with platinum lead-in wire (4) welding of imbedding in the glass bar, molten then imbedding in the glass bar, glass bar overcoat ceramic pipe (3), two ends encapsulate with glass dust and ceramic powder potpourri (5), and be filled with alumina powder (6) at glass bar and sleeve pipe slit, to improve thermo-contact, reduce natural effect, after promptly become applicable platinum resistor temperature measuring element after the annealing.
Claims (2)
1, platinum resistor temperature measuring element, it is characterized in that making skeleton with cutting glass bar (1), platinum filament (2) is in groove, two sections platina silks are made the lead-in wire (4) of resistance measurement, temperature-sensitive platinum filament (2) two ends are drawn with the platinum of imbedding glass bar respectively and are practiced 4) welding, glass bar overcoat ceramic pipe (3), two ends encapsulate with glass dust and ceramic powder potpourri (5), and glass bar and sleeve pipe slit are filled with alumina powder (6).
2,, it is characterized in that wherein the interior platinum filament of groove is a difilar coil according to the platinum resistor temperature measuring element of claim 1.
