Description
Technical field
The present invention relates to thermo bimetal's field of thermometers, specifically a kind of bimetallic thermometer structure.
Background technology
Bimetallic thermometer is a kind of Site Detection instrument for measuring medium and low temperature, and it is existed using double-deck or multiple layer metal
Degrees of expansion different principle work when temperature changes.The bimetallic thermometer of prior art, it is usually in bimetallic one
Connection rotating shaft is held, axis of rotation is driven when bimetallic expands, is realized by the pointer being connected in rotating shaft and the scale of cooperation
Temperature is shown.Therefore the bimetallic thermometer of prior art is still a kind of mechanical instrument, and its temperature accuracy that can be shown has
Limit, it is impossible to meet high-acruracy survey demand.
The content of the invention is it is an object of the invention to provide a kind of bimetallic thermometer structure, to solve prior art bimetallic
The problem of thermometer can not meet high-acruracy survey demand.
In order to achieve the above object, the technical solution adopted in the present invention is：
The thermo bimetal of spiral, heat are vertically provided with a kind of bimetallic thermometer structure, including the conduit being vertically arranged, conduit
Bimetallic upper end is connected with vertical rotating shaft, it is characterised in that：Conduit upper end is connected with upper casing, and upper casing is stretched into the rotating shaft upper end
It is interior, covered at the top of upper casing and be connected with top cover, embedded be provided with display screen, upper casing is provided with encoder, single-chip microcomputer and number in top cover
According to capture card, concentrically axle is connected the encoder axle in encoder with rotating shaft upper end, and output end and the data of encoder are adopted
Truck input is connected, and data collecting card output end access single-chip microcomputer, the display screen also accesses single-chip microcomputer.
A kind of described bimetallic thermometer structure, it is characterised in that：The encoder is erected in top cover by support
Positioned at rotating shaft top position.
A kind of described bimetallic thermometer structure, it is characterised in that：The upper casing internal upper part is provided with insulator, by heat-insulated
Body isolate in top cover and upper casing in, bottom.
A kind of described bimetallic thermometer structure, it is characterised in that：The conduit lower end is connected with Heat Conduction Material and is made
Detecting head, the thermo bimetal lower end is stretched into detecting head.
A kind of described bimetallic thermometer structure, it is characterised in that：The encoder is incremental encoder.
The turn signal of rotating shaft is converted into electric signal by the present invention using encoder, and is exported by data collecting card to list
The signal of encoder is calculated in piece machine, single-chip microcomputer, corresponding temperature value is obtained and is shown by display screen, can be realized
Digital temperature is shown, with higher measurement accuracy.
