Abstract
The utility model discloses a surface platinum resistance thermometer comprises terminal box, construction bolt, thermometer pipe, connecting wire, copper sheet headgear, foraminiferous little preforming and platinum resistance particle, its characterized in that: foraminiferous little preforming setting is at the tip of thermometer pipe, and the connecting wire who draws forth on the platinum resistance particle passes the aperture and is connected to the terminal box, and copper sheet headgear cover is at the head of thermometer pipe, platinum resistance particle clamp between foraminiferous little preforming and copper sheet headgear. Compared with the prior art, the utility model, obvious advantage and positive effect below having: 1. Temperature measurement core parts platinum resistance particle is located copper sheet headgear inner wall, and very near from the point for measuring temperature, the heat conduction situation of copper sheet is good, can correctly measure the true temperature on testee surface, and temperature measurement is higher. 2. Structural shapes it is the same with ordinary platinum resistance thermometer, not only can measure the temperature of testee, can also regard as control heating temperature's components and parts, the utilization ratio is more convenient.
Description
Technical field
The utility model relates to a kind of thermometer, particularly relates to a kind of surperficial platinum-resistance thermometer for measuring body surface temperature.
Background technology
Platinum-resistance thermometer to be current industry be one of the most frequently used thermometer, it and temperature digital display support the use, and not only can measure the temperature of testee, can also, as the components and parts controlling heating-up temperature, use more convenient.The mounting means of the thermometric core parts platinum resistance particle of common platinum-resistance thermometer is generally encapsulated in a larger gummed ceramic body, and leave thermometer head and have certain distance, so the sensitivity experiencing temperature is lower, General Requirements inserts certain degree of depth platinum-resistance thermometer and needs the regular hour just can demonstrate more correct temperature reading, and in fact they are mainly used in the temperature of measurement gas and liquid.
If be metallic objects by what heat, the temperature of the grey headwall steel plate in such as electric precipitator, the temperature wanting to measure its surface is more difficult, a kind of mode is had to be that the head of platinum-resistance thermometer is close to grey headwall, and adopt spring compression, look and consider more thoughtful, in fact error is still larger.Be used for the price is rather stiff of the land surface pyrometer measuring solid surface temperature specially, and can only measuring tempeature be used for, can not as the components and parts controlling heating-up temperature.
Some scientific research institution or quality inspection office, in order to obtain correct temperature value, even taking out the thermometric core parts platinum resistance particle in platinum-resistance thermometer separately to be directly put on heating object or heater housing and directly measuring, quite inconvenient.
The surface temperature of market demand energy correct measurement solid, easy to operate, lower-cost platinum-resistance thermometer.
Utility model content
The utility model surface platinum-resistance thermometer, be made up of terminal box, erection bolt, temperature gauge pipe, connection wire, copper sheet headgear, small preform with holes and platinum resistance particle, it is characterized in that: small preform with holes is arranged on the end of temperature gauge pipe, the connection wire of the extraction on platinum resistance particle is connected to terminal box through aperture, copper sheet headgear is enclosed within the head of temperature gauge pipe, and platinum resistance particle is clipped between small preform with holes and copper sheet headgear.
As preferably, terminal box is by Thin Stainless Steel plate stamping and forming.
As preferably, erection bolt is made up of stainless steel material.
As preferably, temperature gauge pipe adopts stainless-steel tube to make.
As preferably, connect wire and adopt premium insulation copper conductor.
As preferably, copper sheet headgear by copper sheet drawing, its internal diameter and the external diameter of temperature gauge pipe suitable.
As preferably, small preform with holes adopts Thin Stainless Steel plate stamping and forming, its external diameter and the external diameter of temperature gauge pipe suitable.
As preferably, platinum resistance particle has the connection wire that 2 are drawn, connect wire and be connected to terminal box through after the aperture of small preform with holes, copper sheet headgear is enclosed within the head of temperature gauge pipe, and platinum resistance particle is clipped between small preform with holes and copper sheet headgear.
The head of actual surface platinum-resistance thermometer when using directly with got final product measuring tempeature by thermometric object contact; If need the long-time temperature measuring steel plate, an available mounting pipe that is threaded, suitable length is welded on steel plate, and surperficial platinum-resistance thermometer is screwed in mounting pipe, and head touches steel plate.
The utility model compared with prior art, has following obvious advantage and good effect:
1. thermometric core parts platinum resistance particle is positioned at copper sheet headgear inwall, from point for measuring temperature very close to, in order, can go out the true temperature on testee surface by correct measurement, temperature measurement accuracy is higher in the heat conduction of copper sheet.
2. planform is identical with common platinum-resistance thermometer, not only can measure the temperature of testee, can also, as the components and parts controlling heating-up temperature, use more convenient.
