Description
Technical field
This utility model belongs to critesistor processing technique field, particularly relates to a kind of critesistor finished product air
High-precision measurement apparatus in medium.
Background technology
Critesistor, the temperature measuring type NTC critesistor being especially loaded on paper tape, machine and need afterwards to carry out
Detection, present detection device is usually in critesistor is placed on thermostatic oil bath and detects, the most artificially sorts, in perseverance
Measuring in temperature oil groove, production efficiency is low, and labor strength is big, after sorting is measured in oil, needs cleaning, drying, production process
Many twice, the contaminated wastewater environment after cleaning, energy consumption is big, and the production cycle is long, and production efficiency is relatively low, and everyone about produces by every order of classes or grades at school
5000-6000 is only.
NTC thermistor is measured and is typically measured under the conditions of 25 DEG C ± 0.01 DEG C with high-precision oil groove in high precision, thermometric
Type NTC thermistor temperature coefficient is relatively big, is typically-3% ~-5% at room temperature 25 DEG C, just because of this characteristic, application
Broadness, makes sensor by the NTC thermistor of negative temperature coefficient sensitiveer, reflects speed faster, due to high accuracy NTC temperature-sensitive
This characteristic of resistance, measurement resistance accuracy, need to be temperature 25 DEG C ± 0.01 DEG C when the high precision thermosensitive resistor of 1% or 0.5%
In high precision oil groove is carried out.
Measuring high accuracy NTC thermistor with high accuracy oil groove is measuring method current in industry.Use high accuracy oil groove
Measurement exists that equipment investment is big, energy consumption big, environmental pollution, the low inferior a series of drawback of production efficiency.New measurement high accuracy
NTC thermistor method be always primary study direction in industry, under air ambient, how to measure high accuracy NTC temperature-sensitive electricity
Resistance is the great difficult problem of critesistor industry.
By following utility model, finally achieve in air ambient, measure high accuracy NTC thermistor, it is achieved that batch
Quantify to produce, solve the series of malpractice measuring high accuracy NTC thermistor in high accuracy oil groove, it is achieved that in high precision
The revolutionary breakthrough that NTC thermistor is measured, solve measure under oil groove environment environmental pollution, production efficiency low,
Market cannot be met growing and measure operation in producing and seriously restrict the difficult problem of supply to high accuracy NTC thermistor.
25 DEG C of air ambients are measured, it is impossible to use ambient temperature constant control the method for 25 DEG C ± 0.01 DEG C.
The temperature-controlled precision of ambient temperature is required that the probability of the lowest realization is the biggest.The air ambient temperature that following utility model sets exists
In the range of 25 DEG C ± 2 DEG C, this ambient temperature can realize with common convertible frequency air-conditioner.Wide in range owing to measuring ambient temperature, with
Lower utility model proposes a new measurement thinking Comparison Method and measures.Concrete grammar is as follows: with one at high accuracy oil
After the reference resistance measured in groove is as reference, measured resistance is allowed to compare with reference resistance, reference resistance and measured resistance
Same temperature spot is compared, differentiates the accuracy class of measured resistance by the accuracy class of reference resistance.The method
Difficult point be must to be fulfilled for reference resistance and measure on same temperature spot with measured resistance, temperature error controls ± 0.01
In the range of DEG C.This just requires to remanufacture a swiftly flowing sky of subenvironment under 25 DEG C ± 2 DEG C overall situation of air dielectric
Gas medium, flows through reference resistance and measured resistance quickly, simultaneously, and reference resistance is the most close with measured resistance, to base
Quasi-resistance is the smaller the better with the time difference of the matching measurement of measured resistance, measure time difference need in 0.1s, temperature difference ±
Within 0.01 DEG C, for realizing above test subenvironment, take a series of corrective measure and utility model is created, at machinery
All many-sides such as structure, air intake flow, test philosophy, test condition, method of testing have carried out a series of utility model and have created.
The high accuracy NTC thermistor measured in air dielectric is used our company ZL201420055607.5 special
The Principle and method of measurement of profit (a kind of critesistor tester), test philosophy, circuit are controlled all to carry out by this utility model
Substantial amounts of Optimal improvements, reduces the systematic error measured greatly.
During NTC thermistor resistance accuracy ± 0.5%, measure temperature error and must measure higher precision at ± 0.01 DEG C
NTC thermistor needs the oil groove of higher precision, and the oil groove of higher precision (0.001 DEG C) puts into very big, and cost is the highest, Er Qie
Measuring production efficiency in oil groove the lowest, following utility model is that the NTC thermistor measuring higher precision provides complete solution
Certainly scheme, it is thus achieved that important breakthrough.
