Description
Technical field
The utility model is related to a kind of temperature-sensing element, more particularly to a kind of high stability ceramic platinum thermal resistance temperature-sensing element.
Background technology
Existing ceramic platinum thermal resistance temperature-sensing element is typically penetrated in ceramic skeleton with holes by platinum filament, and the tank powdered frit in hole
Or powdered dielectric is filled up, then end is formed with special glaze sealed knot.Because powder has stronger mobility, therefore
Powdered dielectric vibrations, carry rock or use during, all easily powder is rocked, serious can also send out
The problems such as green powder is leaked, therefore stability in use is relatively low, service life is shorter；And due to platinum filament and powdered dielectric
It is separated, therefore in order to improve the intensity of platinum filament, the diameter of platinum filament can not be too thin.
Utility model content
There is provided a kind of anti-vibration resistance in order to solve defect present in above-mentioned prior art and deficiency for the utility model
By force, stability is good during use, and service life is long, and can reduce on the premise of platinum filament intensity is ensured the straight of platinum filament
Footpath, reduces the high stability ceramic platinum thermal resistance temperature-sensing element of production cost.
The technical solution of the utility model：A kind of high stability ceramic platinum thermal resistance temperature-sensing element, including ceramic skeleton, set
Put the capping in ceramic skeleton one end, some platinum filaments being arranged in ceramic skeleton, the lead that is connected on platinum filament and setting
Dielectric outside platinum filament, the platinum filament is coiled into coils shape, and the dielectric is coated on outside platinum filament and platinum filament one
It is body formed, the dielectric circle of dielectric formation solid-like.
Dielectric is integrally formed by the utility model with platinum filament so that the dielectric of dielectric formation solid-like
Circle so that its anti-vibration resistance is strong, and stability is good during use, and service life is long, and platinum filament is integrally formed with dielectric
Afterwards, good product quality so that it can reduce the diameter of platinum filament as far as possible on the premise of intensity is ensured.
Preferably, the capping is ceramic glaze capping.
This kind of structure improves its sealing.
Preferably, the quantity of the platinum filament is two or four, a diameter of 0.01mm-0.019mm of platinum filament.
This kind of structure reduces the cost of manufacture of platinum filament.
Preferably, the dielectric is that dielectric circle is ceramic glaze, rubber, glass or plastics.
Increase the alternative of its dielectric.
Dielectric is integrally formed by the utility model with platinum filament so that the dielectric of dielectric formation solid-like
Circle so that its anti-vibration resistance is strong, and stability is good during use, and service life is long, and platinum filament is integrally formed with dielectric
Afterwards, good product quality so that it can reduce the diameter of platinum filament as far as possible on the premise of intensity is ensured.
