Abstract
The utility model relates to a ceramic platinum thermal resistance thermometer of temperature measuring or wire instrument sensors widely used in the industries of chemical industry, machinery, metallurgy, etc., and comprising a platinum wire 4 and a lead out line 1. The utility model is characterized in that the platinum wire penetrated into the inner bore 9 of a ceramic framework 2, and heat conducting fins 3 are fixed out of the external wall of the ceramic framework. The utility model has the advantages of simple and compact structure, low cost, little platinum wire pollution, long service life, good thermal transport property, etc.
Description
The utility model relates to a kind of ceramic platinum resistance thermometer sensor, thermometer that is widely used in industrial thermometrics such as chemical industry, machinery, metallurgy or line gauge sensor.
As everyone knows, China's platinum-resistance thermometer element is manufactured with the mica frame structure, glass skeleton structure, ceramic skeleton structure, and membrane type (thick film or film) resistance.But in the industrial platinum resistance product was used, a kind of was that glass, pottery or membrane type resistive element are placed the armouring sleeve pipe of having filled magnesia powder, makes the armoured Pt thermal resistance thermometer.Another kind accounts for very large-tonnage remaining mica platinum resistance element is placed in the various pillars, makes the platinum-resistance thermometer of fabricated construction.Mica frame platinum resistance loosely organized, platinum filament exposes, and easily cause platinum filament to pollute, and the platinum resistance ceiling temperature that mica frame is made is lower, (generally in 450 ℃).Resistance to shock is poor.Thereby have influence on the serviceable life of resistance thermometer, and the various glass that will produce now, pottery, membrane type constant resistance place and make assembled platinum resistance thermometer sensor, thermometer in the resistance pillar of fabricated construction, also exist and much be difficult to the making defect that overcomes, as existing said elements, all be columniform, volume is less, and element can not paste tightly mutually with the pillar inwall, it is bad to cause heat to transmit, air conducts heat in the tube, and thermal resistance is bigger, and it is less to add element, vibration in pipe, poor seismic behavior.Abroad have earlier said elements to be made into armouring resistance, place in the assembled resistance pillar again, the platinum-resistance thermometer of the various assembly structures of making (problem that also has poor thermal conduction) is though the feasible cost of manufacture that increased widely is not suitable for China's national situation.
The purpose of this utility model is exactly a kind of simple in structure, compact, pollutions is little, resistance to shock good, heat transmission is got well ceramic platinum resistance thermometer sensor, thermometer of design.
The purpose of this utility model realizes by following structure, pottery platinum resistance thermometer sensor, thermometer, include platinum filament, extension line, it is characterized in that: platinum filament is through in the endoporus of ceramic skeleton, at the intrinsic conducting strip of ceramic skeleton outer wall, the utility model is conducted heat by the conducting strip of platinum filament by ceramic skeleton and its outer wall, thereby has following advantage:
1, simple in structure, compact, easy to make, cost is lower.
2, platinum filament is in ceramic skeleton, and is pollution-free.
3, conducted heat by conducting strip, heat is transmitted better, and friction, and easy to use, the life-span is longer.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of 1 figure is to cut-open view;
Among the figure, 1. extension line 2. ceramic skeletons, 3. conducting strip, 4. in around the formula platinum filament, 5. fixture, 6. dome, 7. platform, 8. groove, 9. endoporus
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model includes platinum filament (4), and extension line (1) is characterized in that: platinum filament is through in the endoporus (9) of ceramic skeleton (2), at the intrinsic conducting strip of ceramic skeleton outer wall (3); The outer porcelain tube clamping of extension line is for convenience installed, and can be provided with platform (7) at the skeleton front end; On the skeleton of platform rear portion, can be provided with dome (6), endwisely slip to prevent porcelain tube; Gu Daorepianchu has the groove (8) that cooperates with conducting strip on skeleton, to increase the stability of fastening conducting strip, as shown in Figure 2, can establish 2 or 4 endoporus on the money of the making pottery skeleton.
Claims (6)
1. a ceramic platinum resistance thermometer sensor, thermometer includes platinum filament (4), and extension line (1) is characterized in that: platinum filament is through in the endoporus (9) of ceramic skeleton (2), at the intrinsic conducting strip of ceramic skeleton outer wall (3).
2. ceramic platinum resistance thermometer sensor, thermometer as claimed in claim 1 is characterized in that: at the ceramic skeleton front end platform (7) is arranged.
