Description
Technical field
The utility model relates to thermometric instruments, especially relates to a kind of low damage and the pinpoint thermopair multi-point temperature measurement probe of energy.
Background technology
Temperature measuring instrument can be divided into contact and contactless two big classes by the thermometric mode.As a rule contact temperature-measuring instrument temperature instrumentation is fairly simple, reliable, measuring accuracy is higher, but because of temperature element and measured medium need carry out sufficient heat interchange, need the regular hour just can reach thermal equilibrium, so there is the delay phenomenon of thermometric, be subjected to the restriction of exotic material simultaneously, can not be applied to very high temperature survey.The contactless instrument thermometric is measured temperature by heat radiation principle, temperature element does not need to contact with measured medium, temperature-measuring range is wide, be not subjected to the restriction of the thermometric upper limit, also can not destroy the temperature field of testee, reaction velocity is generally also than comparatively fast, but is subjected to the influence of the extraneous factors such as emissivity, measuring distance, flue dust and aqueous vapor of object, and its measuring error is bigger.Thermopair is a kind of temperature-sensing element, and it converts temperature signal to the thermopower signal, converts the temperature of measured medium to by electric meter.The ultimate principle of thermocouple temperature measurement is that the homogeneous conductor of two kinds of different components is formed the closed-loop path, when there is thermograde in two ends, just has electric current in the loop and passes through, and just exist thermopower, Here it is so-called Seebeck effect between the two ends this moment.The homogeneous conductor of two kinds of different components is a thermode, and the higher end of temperature is the working end, and the end that temperature is lower is a free end, and free end is under certain stationary temperature usually.Make thermocouple indexing table according to thermopower and functional relationship of temperature, dividing kilsyth basalt is to obtain under the condition of free end temperature in the time of 0 ℃, and different thermopairs has different branch kilsyth basalts.When inserting the third metal material in the thermopair loop, as long as the temperature of two contacts of this material is identical, the thermoelectrical potential that thermopair produced will remain unchanged, and promptly not be subjected to the influence in the third metal access loop.Therefore, when thermocouple temperature measurement, can insert measurement instrument, record thermopower after, promptly know the temperature of measured medium.
At a plurality of positions, a certain zone thermometric, multiple spot thermocouple temperature measurement instrument is widely used.Though the multiple spot thermopair of Xiao Shouing can be realized multimetering in the market, but still has problems: in Bioexperiment, meet the higher biosome of hardness, existing product is difficult for thrusting its inner thermometric; Under strong acid, deep-etching, strong oxidation situation, existing product is very easily impaired; Can't resolve accurate measurement internal temperature Gradient distribution problem, can not describe its temperature field and the governing equation form of the composition.
The utility model content
At the problems referred to above, the utility model provides a kind of low damage and the pinpoint multi-point temperature measurement probe of energy.
The utility model is that the technical scheme that its technical matters of solution is adopted is,
A kind of low damage and the pinpoint multi-point temperature measurement probe of energy; include the anti-corrosion protection sleeve pipe; the material of protective casing is preferably hard PVC (Polyvinylchloride); this protective casing is provided with scale; be provided with thermopair in the protective casing, thermopair is connected on the scale, and the measuring junction of thermopair stretches out the protective casing outside;, arranged in co-axial alignment even in the protective casing outside, the protective casing two ends seal with epoxide-resin glue.
Be filled with the insulation heat-barrier material between described protective casing and the thermopair and between the adjacent heat galvanic couple, this insulation heat-barrier material is preferably magnesium oxide.
The quantity of described thermopair is 2～15.
Scale range on the protective casing and minimum division value are decided on the determinand size.
The beneficial effects of the utility model are; this multi-point temperature measurement probe has adopted the anti-corrosion protection sleeve pipe with the thermopair seal protection, in strong acid, deep-etching Bioexperiment, no matter is gas, liquid or solid; all can accurately measure its internal temperature Gradient distribution, it is simple in structure, the manufacturing assembling is easy.
