Abstract
A magnetic force surface temperature sensor comprises a thermocouple or thermal resistance, a magnet, a brass bushing, an iron protection cage and a stainless steel sleeve head fixed with the iron protection cage, wherein the brass bushing covers the magnet, the iron protection cage covers the brass bushing, and the measurement end of the thermocouple or the thermal resistance is fixed with the magnet and a shielded conductor connected with the measurement end of the thermocouple or thermal resistance passes through the clearance between the magnet and the brass bushing and then passes through the stainless steel sleeve head to be in seal fixation with the stainless steel head. While in use, it is only necessary to absorb the magnet on the steel (iron) device, pipe surface to be measured and it is not necessary to open the hole and weld. The magnetic force surface temperature sensor has advantages of convenient use, sensitive reaction, greatly increased work efficiency and reduced work intensity.
Description
Technical field
The utility model relates to a kind of surface temperature sensor, relates in particular to a kind of surface temperature sensor with magnetic force, is applicable to the measurement of surface temperatures such as reactor that iron and steel makes, high-temperature furnace body, pipeline.
Background technology
For guaranteeing industrial security productions such as petrochemical industry, iron and steel, electric power,,, must measure its surface temperature as the blast furnace of ironmaking, the reactor of oil refining, the gasification furnace of chemical industry, the boiler of electric power and the pipeline of other steel (iron) system etc. to some equipment wherein.Traditional surface temperature sensor all is the surface that is fixed on equipment under test, pipeline with modes such as welding, anchor ear bindings as thermopair, thermal resistance.These modes have following deficiency: 1. welding is fixed, owing to just no longer heat-treat after most equipment is dispatched from the factory, if weld again, the stress that is produced can't be eliminated, meeting reduction equipment intensity is that technology is unallowed, and secondly the welding back will be very loaded down with trivial details when changing or keep in repair temperature sensor, need modes such as cutting or polishing could change waste of manpower and material resources.2. the anchor ear cluster can only be used for small pipeline, then can't implement at main equipment and pipeline, and limitation is very big.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can be adsorbed in the surface temperature sensor that tested steel (iron) control equipment, pipe surface carry out surface temperature measurement, to overcome the defective that existing steel (iron) control equipment, pipe surface temperature survey exist.
The technical solution of the utility model is: a kind of magnetic force surface temperature sensor; comprise thermopair or thermal resistance, magnet, brass bushing, iron protective cover and pullover with the fixing stainless steel of iron protective cover; described magnet overcoat brass bushing; the iron protective cover of brass bushing overcoat; the measurement end and the magnet of described thermopair or thermal resistance are fixed as one, the shielded conductor that is connected with the measurement end of thermopair or thermal resistance by magnet and brass bushing the gap and pass stainless steel pullover with the pullover sealing and fixing of stainless steel.
For further improving the one-piece construction of thermopair or thermal resistance and magnet, described magnet has the resettlement groove of the measurement end of settling thermopair or thermal resistance, and the measurement end of described thermopair or thermal resistance is fixed in the resettlement groove.
For the protection mask lead is not fractureed in junction, the pullover outer end of stainless steel, have buffer action, described shielded conductor is positioned at place, the pullover outer end of stainless steel and is with spring housing.
The utlity model has following beneficial effect: because magnet is set in surface temperature sensor, the measurement end of thermopair or thermal resistance is fixed on the magnet, during use, only need magnet is adsorbed on tested steel (iron) control equipment, pipe surface gets final product, need not perforate, loaded down with trivial details work such as welding, also only needing to take out magnet as the need replacing gets final product, easy to use, be quick on the draw, improved work efficiency greatly and reduced working strength, and need not equipment, pipeline tapping can not reduce the intensity of equipment, also can reduce the leakage of medium simultaneously and cause atmospheric pollution, thereby reach the energy-saving and emission-reduction purpose.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
