Description
Technical field
The utility model relates to a kind of novel temperature measurer, and particularly quartz crystal is as the thermometric field of adopting warm element.
Background technology
Along with China produces and the development of scientific and technical cause, at present, to the mensuration of temperature with to control requirement more and more high, particularly increasing to high precision, high-resolution temperature measuring device requirement.As: with thermometric predict an earthquake, in temperature, aerophor and aircraft engine main shaft in remote measurement seawater and dirt band, in, outer temperature and metering temperature test, needed high precision on research equipment, high resolving power thermometric etc.Matching used Beckman thermometer belongs to mercury class thermometer on all kinds of calorimeters, quick-fried hot instrument, specific heat instrument at present, precision is low, resolution is low, and appearance is glass-encapsulated, can not realize automatic measurement, use and not only bother but also inconvenient, also more difficult to the reading of temperature, personal error is large, and it can only measure relative temperature difference, therefore is difficult to satisfy customer requirements, and has correspondingly restricted the development of scientific research cause.Be the measurement of 0.001 ℃ for resolution now, with high-quality direct current comparison expression constant temperature electric bridge and First class standard platinum electronic thermometer adapted, measure under strict environmental baseline, troublesome poeration, calculation of complex, expensive, more can not do remote remote measurement and high precision and control.
Summary of the invention
The utility model provides a kind of high-precision quartz crystal temperature measurer for addressing the aforementioned drawbacks, his cardinal principle be with quartz crystal under certain corner cut, temperature variation causes that quartz crystal frequency becomes the characteristics that certain linearity changes and makes.The technical scheme that solves is: Cai Wen system (1), relaying or emission coefficient (2), observing and controlling temperature system (3), disposal system (4), becoming frequency to pass through relaying or emission coefficient (2) temperature transition that collects by Cai Wen system (1) sends observing and controlling temperature system (3) to and receives and frequency inverted is become temperature, then realize the functions such as calculating, storage, printing, warning by disposal system (4).It is characterized in that: the probe of described Cai Wen system (1) is quartz crystal sensor, converts dut temperature to frequency.
The probe of described Cai Wen system (1) is 1-N, and wherein N is integer;
Described observing and controlling temperature system (3) comprises adopts warm module, temperature control module, temperature measurement module.
Described observing and controlling temperature system (3) also comprises relaying or receiving system.
Described disposal system (4) calculating, storage, printing, warning etc. realize on a circuit board.
The technical characterstic that this programme brings is: become certain linear changing relation, temperature variation to cause the characteristics that frequency changes according to the quartz crystal temperature with frequency and carry out the observing and controlling temperature of high precision, high resolving power, high stability.produce with the utility model scheme, the temperature measurer of making is compared with other temperature measurers, has resolution high (0.0001 ℃ can increase to 0.00005 ℃), precision high (automatically regulating with testing apparatus), the remote remote measuring and controlling of energy (adopt emission or receive), be complementary with soft (firmly) part of designed, designed, realize that record shows automatically, storing data automatically, automatic printing, automatically revise, automatic alarm, automatically displays temperature and corresponding frequency, energy auto switching electric source (220V, the characteristics such as 12V), this is that domestic other any temperature measurers can not reach at present.
Description of drawings:
Fig. 1 is the utility model workflow diagram.
Embodiment: quartz crystal sensor is placed on the observing and controlling warm spot, by Cai Wen system 1, the temperature that collects is become frequency, by relaying or emission coefficient 2, frequency is sent to observing and controlling temperature system 3 again, system accepts again frequency to be converted into temperature by the observing and controlling temperature, and reduction formula is: ft=f
0+ α t+ β t
2+ γ t
3+ ..., wherein ft is the frequency values of dut temperature, f
0Be the frequency starting point, α, β, γ are respectively the fixed constant that calculates in observed temperature and frequency characteristic test, and t is tested controlling temperature.And then will be converted into temperature t in the substitution formula such as α, β, γ.Realize at last the functions such as calculating, storage, printing, warning by disposal system 4.
