The utility model discloses can carry out temperature measurement, have the higher measurement accuracy and the degree of accuracy.

Description

The differential transformer of temperature can be measured

Technical field

This utility model relates to field transformer, a kind of differential transformer measuring temperature.

Background technology

Transformator be the principle utilizing electromagnetic induction to change the device of alternating voltage, differential transformer is the one of transformator Kind, it is used for measuring the non electrical quantity parameters such as displacement, pressure, vibration, but still not used for the differential transformer structure measuring temperature.

Utility model content technical problem to be solved in the utility model is to provide a kind of measures the differential of temperature Transformator, when the temperature is changed, cylinder deforms under thermic telescopic action in its design, and then change secondary coil passes through Magnetic flux, it is achieved measure function, there is higher certainty of measurement and accuracy.

In order to solve above-mentioned technical problem, the technical scheme that this utility model is used is:

A kind of differential transformer measuring temperature, it is characterised in that: including the body of circle, body one end pipe end seals Closing formation blind end, body other end pipe end is the mouth of pipe, and tube wall is provided with three sections of winding slots, wherein middle coiling vertically Groove is wound with primary coil, remaining two sections of winding slot is wound with secondary coil, and two secondary coil differential concatenations, in body Sequentially coaxially be equipped with elastic rubber column to the mouth of pipe from blind end, cylinder that iron core, thermic telescopic material are made, described cylinder Iron core, elastic rubber column are closely pressed in body by body, and cylindrical member at one end flushes with tube mouth or slightly exceeds body pipe Mouthful.

Described a kind of differential transformer measuring temperature, it is characterised in that: described tube mouth outer wall is provided with assembling Land.

The utility model has the advantages that:

In this utility model, utilize cylinder to flush with the mouth of pipe or exceed the end thereof contacts testee of the mouth of pipe, working as temperature During change, cylinder deforms under thermic telescopic action, makes iron core move extruding elastic rubber column, and then changes in secondary coil The magnetic flux passed through, it is achieved measure function.This utility model can carry out temperature survey, has higher certainty of measurement with accurate Degree.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

Detailed description of the invention

Shown in Figure 1, a kind of differential transformer measuring temperature, include the body 1 of circle, body 1 one end is managed End seal closes formation blind end 2, and body 1 other end pipe end is the mouth of pipe, and body 1 outer wall is provided with three sections of winding slots, Qi Zhongzhong vertically Between winding slot in be wound with primary coil 3, remaining two sections of winding slot is wound with secondary coil 4, and two secondary coils 4 is reverse Series connection, is sequentially coaxially equipped with elastic rubber column 5 from blind end 2 in body 1, iron core 6, thermic telescopic material are made to the mouth of pipe Cylinder 7, iron core 6, elastic rubber column 5 are closely pressed in body 1 by cylinder 7, and cylinder 7 one end is neat with body 1 mouth of pipe Put down or slightly beyond tube mouth.Body 1 mouth of pipe outer wall is provided with assembling land 8.

Claims (2)
