Abstract
The utility model relates to a portable asphalt thermometer, mainly comprising a temperature probe, compensating wires and a plug connected with an apparatus casing; the temperature probe is connected with an automatic temperature compensator and a data processing display through the compensating wires and the plug, so that the utility model can measure different temperature in high or low temperature ranges; not only the asphalt inserting temperature but also the surface temperature of the asphalt pavement can be measured. The utility model has the advantages of small size, easy carrying, easy use and direct number reading and can be widely used in all kinds of engineering temperature measurement situations.
Description
A kind of portable pitch thermometer relates to a kind of physical measuring instrument, particularly relates to a kind of measuring appliance of measuring the asphalt temperature in highway and other engineerings.
Build in the labour at present highway and Other Engineering, need carry out thermometric to the pitch of different temperatures, thereby the control construction quality was generally measured with thermometer is manual in the past, and not only the temperature difference is very big but also inconvenience very, at present both at home and abroad, also begin to measure, but this thermometer generally can only be used in high temperature section application more than 600 ℃ with thermocouple thermometer, and because volume is big, operation inconvenience especially can not be suitable for the working-yard.
The utility model provided a kind of can be applied to high and low temperature section thermometric fast, portable novel thermometer.
Realize that technical characterictic of the present utility model is made up of temp probe, Automatic Temperature Compensator, data processing display, temp probe shows with data processing through Automatic Temperature Compensator and is connected.
As sensor, be made up of thermopair and wide sensing membrane by wide surface temperature probe by the K type thermocouple for temp probe, and thermopair is connected by taking film spot with wide sensing membrane.
Automatic Temperature Compensator mainly is made up of the semiconductor heat photosensitive elements.Data processing display mainly is made up of counting, memory, decoding scheme and logic control circuit and display.
Be further described below in conjunction with accompanying drawing.
Fig. 1 is a pitch thermometer complete machine electrical schematic diagram, wherein:
The 14th, Automatic Temperature Compensator circuit, the 15th, data processing display circuit, the 16th, mu balanced circuit, IC

Fig. 3 be the data processing display synoptic diagram wherein:
IC

Fig. 4 shows wide surface temperature probe synoptic diagram for the road.Wherein:
1, electrode wires, 2, the protection connecting link, 3, Insulation Material, 4, the protection outer cover, 5, the insulation gland, 6, sensing membrane, 7, take film spot.
Fig. 5 is the machine shape synoptic diagram.Wherein:
8, temperature probe, 9, compensating wire, 10, plug, 11, display board, 12, shell, 13, power switch.
In the accompanying drawing, when temp probe 8 inserts pitch or contact bituminous pavement surface, become electric signal to output to Automatic Temperature Compensator 14 thermal power transfer by compensating wire 9.Automatic Temperature Compensator 14 mainly is made up of the semiconductor heat photosensitive elements, plays from motion tracking compensating action.Signal outputs to data processing display 15 again behind Automatic Temperature Compensator 14, by the synthetic conversion to compensating signal and measuring-signal, demonstrate temperature value at last in display, finishes whole temperature survey work.
As embodiment, temperature probe is a kind of plug-in type pitch thermometer, and as sensor, thermopair is in the contact insertion pitch to be measured probe, can make things convenient for direct-reading to go out temperature with the K type thermocouple.
As another kind of embodiment; temperature probe is made wide surface temperature probe; there is protection connecting link 2 thermopair electrode wires 1 outside; the 3rd, Insulation Material; the 4th, protection outer cover, the 5th, insulation cover plate, the 6th, wide sensing membrane; thermopair electrode 1 is touched membrane process with wide sensing membrane 6 usefulness and is connected; the 7th, its connection take film spot because the tight sensing contact film of thermopair electroplax, and adopt and take membrane technology; so its heat conduction equilibration time is extremely short; test area is big, and accuracy of reading is because generic point contact thermography probe can not be measured the road surface temperature exactly; because it is sliding that highway road table generally is not non-ordinary light; smooth, so the some temperature of road table one section is not directly just to represent the Lu Biao temperature.Use this wide surface temperature probe, the sensing membrane size is big, can utilize it to measure the long-pending medial temperature of a road surfaces and reflect its whole road table temperature.
As can see from Figure 5, this apparatus structure is simple, volume is little, and is easy to carry, can make things convenient for by plug 10 and promptly to change temperature probe, both can survey the insertion temperature of pitch, can survey the road surfaces temperature again, both can the pyrometry temperature, can survey cryogenic temperature again.So can be widely used in the occasion that many construction works need thermometric.
