the utility model discloses with temperature sensing structure mounting outside the sleeve pipe, adopt the insulating part to separate temperature sensing structure and sleeve pipe, greatly reduced sheathed tube thermal inertia makes the temperature measurement more timely and accurate to temperature sensing element's influence, improves temperature sensor's detection precision, reduces temperature sensor's response time.
Drawings
The present invention will be further explained with reference to the drawings and examples;
fig. 1 is a schematic overall structure diagram of the preferred embodiment of the present invention;
in the figure: 1. a sleeve; 2. a junction box; 3. a temperature sensing structure; 4. an insulating member.
Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.
As shown in fig. 1, a high-precision and fast-response temperature sensor comprises a sleeve 1, a junction box 2 located at one end of the sleeve 1, and a temperature sensing structure 3 located at the other end of the sleeve 1; the sleeve 1 is detachably connected with the junction box 2, the temperature sensing structure 3 is connected with the sleeve 1 through the insulating piece 4, and the temperature sensing structure 3 comprises a protection tube and a temperature sensing element positioned in the protection tube.
In this embodiment, the temperature sensing element adopts the thermocouple to receive the temperature signal, and the protection tube can be made into a corresponding shape structure according to the actual working conditions to mount and protect the temperature sensing element, and when the temperature sensing element receives the temperature signal, because the temperature sensing element is outside the sleeve 1, the influence of the thermal inertia of the sleeve 1 on the temperature sensing element can be greatly reduced, and the detection precision is improved.
In the present embodiment, the sleeve 1 is a metal material piece, and specifically, an aluminum pipe is used.
In this embodiment, the temperature sensing element may also use a thermal resistor.
Further, the sleeve 1 is connected to the terminal block 2 by a screw.
In this embodiment, the insulating member 4 is a non-metal member, and specifically, a ceramic member is used.
To sum up, the utility model discloses install temperature sensing structure 3 outside sleeve pipe 1, adopt insulating part 4 to separate temperature sensing structure 3 and sleeve pipe 1, greatly reduced sleeve pipe 1's thermal inertia makes the temperature measurement more timely and accurate to temperature sensing element's influence, improves temperature sensor's detection precision, reduces temperature sensor's response time.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
