Description
Technical field
The utility model relates to a kind of instruments used for education of thermal resistance, particularly a kind of thermal resistance characteristic demonstration device.
Background technology
Thermal resistance is temperature element the most frequently used during commercial production controls, its temperature-measuring range is-200 DEG C to 500 DEG C, the change of temperature is converted to resistance variations and exports by it, due to the abstract indigestion of its principle of work, especially what will adopt three-wire system to be confused about, this content of courses that also result in this part becomes difficult point, does not also have this type of instruments used for education at present.
Utility model content
The technical problems to be solved in the utility model is why provide a kind of by the principle of work of thermal resistance and can adopt the vivid thermal resistance characteristic demonstration device showed of three-wire system connection.
For achieving the above object, the utility model is realized by following technical scheme:
A kind of thermal resistance characteristic demonstration device, it is characterized in that, comprise base, spirit lamp, support, thermal resistance, wire, touch-screen, printer, telecommunication cable, clip and resistance box, described spirit lamp, touch-screen, printer and resistance box are all placed on base, described support is screwed and is arranged on base, described thermal resistance, resistance box and touch-screen are electrically connected by wired in series, described thermal resistance is fixedly mounted on support by the clip be arranged on support, and described touch-screen is electrically connected with printer by telecommunication cable.
Further, described resistance box is precision resistance case, and model is ZX75.
The beneficial effects of the utility model are, provide a kind of be easy to carry and can in real time numeral and the curve display resistance of thermal resistance and temperature change, showed the instruments used for education of line resistance on the impact of measuring accuracy intuitively, thus help student understands Thermistor Temperature Measurement why will adopt three-wire system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Implication is marked as follows in accompanying drawing:
1, base 2, spirit lamp 3, support 4, thermal resistance 5, wire 6, touch-screen 7, printer 8, telecommunication cable 9, clip 10, resistance box.
Embodiment
Below in conjunction with diagram and specific embodiment, the utility model is described in further detail.
With reference to Fig. 1, a kind of thermal resistance characteristic demonstration device of the utility model, comprise base 1, spirit lamp 2, support 3, thermal resistance 4, wire 5, touch-screen 6, printer 7, telecommunication cable 8, clip 9 and resistance box 10, described spirit lamp 2, touch-screen 6, printer 7 and resistance box 10 are all placed on base 1, described support 3 is screwed and is arranged on base 1, described thermal resistance 4, resistance box 10 and touch-screen 6 are electrically connected in series by wire 5, described thermal resistance 4 is fixedly mounted on support 3 by the clip 9 be arranged on support 3, described touch-screen 6 is electrically connected with printer 7 by telecommunication cable 8.
Further, described resistance box 10 is precision resistance case, and model is ZX75.
The course of work of the present utility model: positive stroke demonstration: working end spirit lamp 2 being shifted at leisure from far near thermal resistance 4, now the temperature of thermal resistance 4 changes from low to high, its resistance value exported shows the resistance of thermal resistance and the temperature of thermal resistance corresponding with it on touch-screen 6 simultaneously, display mode statistics have shown and the display of real time temperature curve, the resistance of period change resistance box 10, measurement circuit resistance is on the impact of measuring accuracy, and then be illustrated as what thermal resistance and will adopt three-wire system connection, how to eliminate the measuring error that line resistance causes, the temperature-resistance demonstration data of thermal resistance can be printed by printer 7, revesal is demonstrated, and spirit lamp 2 extremely far is moved apart thermal resistance 4 by near, and now the temperature of thermal resistance 4 changes from high to low, after this carries out revesal demonstration.In presentation process, touch-screen 6 in real time numeral and curve shows the resistance of thermal resistance and the change of temperature, and the principle of work of thermal resistance is showed visually, and student can also observe line resistance intuitively on the impact of measuring simultaneously.
