Abstract
The utility model relates to a pressure type thermometer. The thermometer is composed of an indicating meter, a capillary tube and a thermal bulb; one end of the capillary tube is connected with the indicating meter, and the other end is connected with the thermal bulb; a temperature dial gauge is arranged on the indicating meter; an elastic element is arranged inside the indicating meter; and a temperature sensing liquid is arranged inside the thermal bulb. Compared with the prior art, the pressure type thermometer of the utility model has the advantages of structural simplicity, convenient manufacture, high-accuracy temperature detection and the like.
Description
Technical field
The utility model relates to a kind of surveying instrument, especially relates to a kind of pressure-type thermometer.
Background technology
Thermometer commonly used is exactly to utilize the principle of expanding with heat and contracting with cold of mercury or other temperature sensing liquids to come the directly temperature of demonstration measured medium; But they are difficult to be applicable to that the measurement of some equipment medium temperature shows; In addition; In some heat conduction or the very fast occasion of convection current, thereby the rate of change of thermometer can obviously lag behind and causes that the result's is inaccurate.
The utility model content
The purpose of the utility model is exactly to provide a kind of simple in structure for the defective that overcomes above-mentioned prior art existence, and easily manufactured, detected temperatures is pressure-type thermometer accurately.
The purpose of the utility model can realize through following technical scheme:
A kind of pressure-type thermometer is characterized in that, this pressure-type thermometer is made up of indicating instrument, kapillary and thermometer bulb, the L-shaped structure of described kapillary, and an end capillaceous connects indicating instrument, and the other end connects thermometer bulb through snap fastener.
Described indicating instrument is provided with the temperature scale table.
Be provided with flexible member in the described indicating instrument, this flexible member is connected with the pointer of temperature scale table.
Be provided with temperature sensing liquid in the described thermometer bulb.
Compared with prior art, the utility model is simple in structure, and is easily manufactured, through the test that oil temperature is changed, utilizes volume change to produce pressure and changes, and then be converted into mechanical shift and amplify through machinery the result is detected in real time, and the result more in real time accurately.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
A kind of pressure-type thermometer, its structure is as shown in Figure 1, is made up of indicating instrument 1, kapillary 2 and thermometer bulb 3; Kapillary 2 one ends connect indicating instrument 1, and the other end connects thermometer bulb 3, and indicating instrument 1 is provided with temperature scale table 4; Be provided with flexible member in the indicating instrument 1, be provided with temperature sensing liquid in the thermometer bulb 3.When temperature of oil in transformer changed, the volume of temperature sensing liquid changed thereupon, and this volume change is delivered to indicating instrument 1 through kapillary 2.In indicating instrument 1, have elastic component, volume change is converted into mechanical shift, amplify, drive indicating instrument 1 indication through machinery, thus the variation of expression oil temperature.
Claims (4)
1. a pressure-type thermometer is characterized in that, this pressure-type thermometer is made up of indicating instrument, kapillary and thermometer bulb, the L-shaped structure of described kapillary, and an end capillaceous connects indicating instrument, and the other end connects thermometer bulb through snap fastener.
2. a kind of pressure-type thermometer according to claim 1 is characterized in that described indicating instrument is provided with the temperature scale table.
