Abstract
Provided is a resistance thermometer for an end surface, belonging to the technical field of resistance thermometers. The resistance thermometer comprises a compensation lead (1); and is characterized in that the end of the compensation lead (1) is welded with a film component (5), a protection tube (6) sleeves the film component (5), a spring (4) and a hollow bolt (3) sleeve the compensation lead (1), one end of the spring (4) is connected with the film component (5), the other end of the spring (4) is connected with the hollow bolt (3), the outer ring of the hollow bolt (3) is connected with a nut, and a connecting position of the protection tube (6) is sealed with sealant so that the film component (5) therein is sealed. The resistance thermometer for the end surface can be tightly connected with an object to be measured, improves the measuring velocity and precision, and can satisfy the requirement of precise use.
Description
Technical field
End face thermal resistance, belongs to thermal resistance technical field, be specifically related to one can with the close-connected thermal resistance of testee end face.
Background technology
Thermal resistance is the most frequently used a kind of Temperature Detector in middle low-temperature space, and Thermistor Temperature Measurement is that the resistance value based on metallic conductor increases this characteristic with the increase of temperature and carries out thermometric.At present, traditional thermal resistance product, due to the restriction of its contour structures, cannot with testee close contact, make its thermometric reliability poor, cause measuring thermotonus slow, measurement result is inaccurate, cannot meet the request for utilization that measurement result is required to more accurate user.
Summary of the invention
?the technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of and can closely be connected with measured object, improve measuring speed and precision, meet the end face thermal resistance of accurate request for utilization.
The utility model solves the technical scheme that its technical matters adopts: this end face thermal resistance; comprise compensating wire; it is characterized in that: described compensating wire termination welding thin-film component; thin-film component is set with protection tube outward; spring and hollow bolt are enclosed within compensating wire outer ring; spring one end connects thin-film component, and the other end connects hollow bolt, and hollow bolt outer ring is connected with nut.Can make thin-film component and protection tube closely near testee by spring force, hollow bolt can be threaded with testee simultaneously, makes to measure more quick and precisely, and spring plays the effect of becoming flexible of preventing.
The junction of described protection tube seals by sealing, makes inner thin-film component in sealing state.Ensure the contact of thin-film component discord extraneous air, improve measuring accuracy.
The cavity termination of described hollow bolt is provided with shoulder hole, and spring is fixed by withstanding on shoulder hole.
Described compensating wire adopts tetrafluoro three-core shielding line, adopts three-wire system, improves the degree of accuracy of product.
Described protection tube adopts stainless steel to make.
On described nut, print and have numbering.
Compared with prior art, the beneficial effect that the utility model has is:
1, this end face can make thin thermometric end close contact testee with thermal resistance by spring force, and simultaneously hollow bolt can be threaded with testee, and spring plays the effect of becoming flexible of preventing, makes to measure more quick and precisely, meets accurate request for utilization.
2, the junction of protection tube seals by sealing, makes inner thin-film component in sealing state, isolates completely with the external world, improves measuring accuracy, and guarantee increases the service life.
Brief description of the drawings
Fig. 1 is the structure cut-open view of this end face thermal resistance.
Fig. 2 is the scheme of installation of this end face thermal resistance.
Wherein: 1, compensating wire 2, nut 3, hollow bolt 4, spring 5, thin-film component 6, protection tube 7, axle bush 8, bearing shell.
Embodiment
Fig. 1 ~ 2nd, most preferred embodiment of the present utility model, is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1: end face thermal resistance, comprise compensating wire 1, compensating wire 1 adopts tetrafluoro three-core shielding line.Compensating wire 1 termination welding thin-film component 5, thin-film component 5 is outer is set with protection tube 6, and the junction of protection tube 6 seals by sealing, makes inner thin-film component 5 in sealing state, and protection tube 6 adopts stainless steel to make.Spring 4 and hollow bolt 3 are enclosed within compensating wire 1 outer ring, spring 4 one end connect thin-film component 5, the other end connects hollow bolt 3, the cavity termination of hollow bolt 3 is provided with shoulder hole, spring 4 is fixed by withstanding on shoulder hole, hollow bolt 3 outer rings are connected with nut 2, on nut 2, print and have numbering.
Principle of work is as follows, with reference to accompanying drawing 2: this end face can be for measuring motor bearing, plastics machinery, power plant steam turbine, mould or other body surface temperature with thermal resistance.To measure motor bearing temperature as example; in the time using; this end face stretches into axle bush 7 and bearing shell 8 inside with thin-film component 5 and protection tube 6 ends of thermal resistance; thin-film component 5 and protection tube 6 withstand on bearing shell 8 by the elastic force of spring 4; form and be closely connected with bearing shell 8; simultaneously hollow bolt 3 is threaded with axle bush 7 formation, and fastening nut 2 prevents from becoming flexible, and just can measure quickly and accurately motor bearing temperature after connection.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
