Abstract
The invention discloses an armored thermal resistor for an explosion-proof fan, relating to the technical field of temperature sensors. The armored thermal resistor comprises a temperature measuring element, a metal protection tube, a porous mounting base, a junction box, a connector base, a lead wire and a lead wire protective sleeve. The temperature measuring element is arranged at one end in the metal protection tube, and the other end of the metal protection tube is fixed on the porous mounting base and is connected to the lead wire through the connector base. The connector seat is arranged in the junction box, and the outer side of the junction box is also provided with the lead wire protective sleeve. The armored thermal resistor has the advantages of simple structure, convenient and reliable use and strong practicability, the temperature measurement of different depths and positions can be carried out.
Description
Technical field
What the present invention relates to is temperature sensor technical field, is specifically related to a kind of explosion-proof fan armoured thermal resistance.
Background technology
Explosion-proof fan armoured thermal resistance is a kind of temperature sensor, utilize material when temperature variation, and its resistance is also along with the feature changing is measured temperature.When change in resistance, work instrument just demonstrates the corresponding temperature value of resistance.General a kind of thermal resistance can only carry out temperature survey to the device of the same degree of depth, for diverse location, does not allow the measurement of the degree of depth need to use even a plurality of thermal resistances of difference to install and measure, and very inconvenient, practicality is not strong.
Summary of the invention
For the deficiency existing in prior art, the invention provides a kind of explosion-proof fan armoured thermal resistance, simple in structure, can carry out the temperature survey of different depth and position, easy to use and reliable, practical.
To achieve these goals; the present invention realizes by the following technical solutions: a kind of explosion-proof fan armoured thermal resistance; comprise temperature element, protection metal pipe, porous mount pad, terminal box, junction block, lead-in wire and pilot protection cover; temperature element is arranged on the inner one end of protection metal pipe; the protection metal pipe other end is fixed on porous mount pad; and be connected with lead-in wire by junction block, junction block is arranged in terminal box, terminal box outside is also provided with pilot protection cover.
According to above-mentioned a kind of explosion-proof fan armoured thermal resistance, wherein, described temperature element and protection metal pipe are integral type structure.
According to above-mentioned a kind of explosion-proof fan armoured thermal resistance, wherein, on described porous mount pad, a plurality of thermal resistances can be installed, a plurality of thermal resistances can be used measurement simultaneously.
The present invention is simple in structure, can carry out the temperature survey of different depth and position, easy to use and reliable, practical.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the present invention in detail;
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
With reference to Fig. 1; this embodiment is by the following technical solutions: a kind of explosion-proof fan armoured thermal resistance; comprise temperature element 1, protection metal pipe 2, porous mount pad 3, terminal box 4, junction block 5, lead-in wire 6 and pilot protection cover 7; temperature element 1 is arranged on the inner one end of protection metal pipe 2; protection metal pipe 2 other ends are fixed on porous mount pad 3; and be connected with lead-in wire 6 by junction block 5, junction block 5 is arranged in terminal box 4, terminal box 4 outsides are also provided with pilot protection cover 7.
It should be noted that described temperature element and protection metal pipe 2 are for integral type structure.
In addition, on described porous mount pad 3, a plurality of thermal resistances can be installed, a plurality of thermal resistances can be used measurement simultaneously.
The explosion-proof fan of this embodiment adopts composite armoured electric thermo-couple as temperature element with armoured thermal resistance, and thermal response time is fast; Its protection tube has very strong antipollution and good physical strength, is applicable to being arranged on the severe occasion of environment; Porous mount pad 3 can be realized multiple spot access thermal resistance, and a plurality of thermal resistances can be used for measurement space gradient temperature or medial temperature, also can measure the temperature of a plurality of different depths and position.
This embodiment is simple in structure, can carry out the temperature survey of different depth and position, easy to use and reliable, practical.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
