Abstract
This invention relates to a sensor for testing temperature according to the law of conductor resistance varing along with the of temperature which comprises a Teflon jacket tube, a Pt thermal resistor, a pyrocondensate tube, wiring plate in which the Pt thermal resistor ic onnected with the wiring plate via conducting wire passing through the pyrocondensate tube the Pt thermal resistor, the conducting wire and pyrocondensate tube are sleeved with Teflon jacket tubes, the Pt thermal resister is close to tube wall and inside wall of sealing bottom of the Teflon, the outer wall of the pyrocondensate tube is sleeved with the wall of the Teflon jacket mainly used in testing temperature in aid solution above 250 deg.C.
Description
Technical field
The present invention relates to the instrument of a kind of temperature survey and control, especially a kind ofly vary with temperature the temperature sensor that rule is measured temperature according to conductor resistance.
Background technology
The temperature-sensing element that the most frequently used resistance thermometer all adopts tinsel to turn to.Mainly contain platinum-resistance thermometer and copper electrical resistance thermometer, accurate platinum-resistance thermometer is the highest thermometer of accuracy of measurement at present.Existing platinum resistance sensor is generally made outer protection tube with metal material; metal material is used stainless steel material always; but in general acid solution; its corrosion resistance is very poor; so be higher than thermometric under 250 degrees centigrade the sour environment; often outside the stainless steel protection pipe, overlap a teflon sleeve again; though solved the anticorrosive problem of thermometric in acid solution like this; but its volume increases (diameter is more than φ 12mm); length is no more than 2 meters; thermal inertia is big, and reaction is slow, and measuring accuracy is also very low.Meanwhile, the element of used in the world temperature sensor is more and more littler, and is also more and more higher to accuracy requirement.
Summary of the invention
The purpose of this invention is to provide a kind of platinum resistance sensor, in order to the problems such as anticorrosive, volume increase, thermal inertia and measuring accuracy that solve in the prior art in acid solution thermometric.
The object of the present invention is achieved like this: the present invention is made up of teflon sleeve, platinum resistance thermometer sensor,, heat-shrink tube, lug plate; Wherein platinum resistance thermometer sensor, passes heat-shrink tube by lead and is connected with lug plate, platinum resistance thermometer sensor,, lead and heat-shrink tube are with teflon sleeve outward, platinum resistance thermometer sensor, is near the tube wall of teflon sleeve and the inwall at teflon back cover place, and the outer wall of heat-shrink tube and the tube wall of teflon sleeve be noose mutually.
Compared with prior art, the present invention has following obvious effect:
1, the volume-diminished of product, diameter can narrow down to φ 5～φ about 4 by original φ 14, is easy to carry.
2, save alloy materials such as stainless steel, reduced production cost.
3, thermal inertia is little, and temperature-sensitive speed is fast, the temperature measurement accuracy height.
4, drawing conductor spacing increases, and is increased to tens of rice from original 1～2 meter.
5, because employing is all made protection tube by teflon sleeve, and corrosion resistance is strong, prolong life of product.
Description of drawings
Fig. 1 is the structural representation of platinum resistance sensor of the present invention.
Wherein the contrast of Reference numeral and title is as follows:
1---teflon sleeve back cover place 2---teflon sleeve
3---platinum resistance thermometer sensor, 4---heat-shrink tube
5---lug plate
With reference to accompanying drawing, in conjunction with the embodiments, the invention will be further described.
Embodiment
As can be seen from Figure 1, the present invention is made up of teflon sleeve 2, platinum resistance thermometer sensor, 3, heat-shrink tube 4, lug plate 5; Wherein platinum resistance thermometer sensor, 3 passes heat-shrink tube 4 by lead and is connected with lug plate 5, platinum resistance thermometer sensor, 3, lead and the heat-shrink tube 4 outer teflon sleeves 2 that are with, platinum resistance thermometer sensor, 3 is near the tube wall of teflon sleeve 2 and the inwall at teflon sleeve back cover place 1, and the tube wall of the outer wall of heat-shrink tube 4 and teflon sleeve 2 socket-connects.
Critical process of the invention process is the welding back cover of teflon sleeve, it requires weld definitely tightly seamless, it can be under normal pressure, carry out the thermometric operation in mordant liquid above 250 degrees centigrade or the gas, facts have proved the seepage that liquid or gas do not take place, guaranteed the quality of product and the precision of thermometric.
