Abstract
The utility model discloses a humidity sensor for a high-temperature environment, which comprises an aluminum sensor shell (1). The humidity sensor is characterized in that the lower part of the shell (1) is provided with a bottom cover (2); the upper end of the shell (1) is provided with an opening (3); the opening (3) is internally provided with a metal net (4); a metal bolt (5) penetrates through the bottom cover (2); a humidity-sensitive element (7) is clamped at the screw cap of the upper part of the metal bolt (5); and the upper part of the humidity-sensitive element contacts the copper electrode (8) fixed in the shell (1). The humidity sensor disclosed by the utility model is simple in structure, ingenious in design and reasonable in arrangement and can measure the air humidity in a high-temperature environment.
Description
Technical field
The utility model relates to a kind of humidity sensing device, particularly a kind of humidity sensing device that can use under hot environment.
Background technology
The resistance that metal oxide ceramic is made is very responsive to airborne water vapour content (being air humidity), according to its this specific character, now metal oxide ceramic is used as the humidity-sensitive element in the humidity sensor.Traditional way is that the surface of potsherd (being humidity-sensitive element) is starched printing and sintered pair of electrodes into silver, and utilize the mode of soldering to add lead-in wire thereon, and its inclosure is inner with the metal shell of wire netting, form a complete humidity sensor.But because this lead-in wire mode need be utilized welding, therefore can't be applied in the measurement of carrying out air humidity in the hot environment.So need now a kind of Novel humidity sensor that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, can carry out the humidity sensor that air humidity is measured under hot environment.
Technical solution of the present utility model is: the humidity sensor that uses under a kind of hot environment, the sensor housing 1 that comprises aluminum, it is characterized in that: the bottom of described housing 1 is bottom 2, the upper end offers opening 3, in opening 3, be provided with wire netting 4, in bottom 2 interior cross-under metal bolts 5 is arranged, the nut place, top of metal bolts 5 clamps by nut 6 humidity-sensitive element 7, and the top of humidity-sensitive element 7 contacts with the copper electrode 8 that is fixed on housing 1 inside.
The utility model is compared with prior art, has following advantage:
The humidity sensor of this kind of version, it is simple in structure, design ingenious, rationally distributed, traditional utilize metal oxide ceramic as the humidity sensor of humidity-sensitive element in preparation process, lead-in wire is to utilize the mode of welding to be fixed on the humidity-sensitive element, when therefore if this humidity sensor is worked under hot environment, second melting might appear in scolding tin, the connection effect of impact lead-in wire, even cause humidity sensor to work.For the problems referred to above, the utility model embodiment designs a kind of special construction that utilizes metal bolts to fix humidity-sensitive element, and this metal bolts itself also plays the effect of wire, is not subjected to the impact of hot environment.The manufacture craft of this humidity sensor is simple, and is cheap for manufacturing cost, can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market outlook are very wide.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: the humidity sensor that uses under a kind of hot environment, comprise one as the sensor housing 1 on basis, this housing 1 adopts aluminium to make, be provided with bottom 2 in the bottom of housing 1, housing 1 upper end offers opening 3, in opening 3, then be provided with wire netting 4, be fixed with metal bolts 5 in bottom 2 interior cross-under, the nut on these metal bolts 5 tops and nut 6 jointly clamp humidity-sensitive element 7, fix, and the top of humidity-sensitive element 7 is in contact with one another with the copper electrode 8 that is fixed in the housing 1.
The course of work of the humidity sensor that uses under the hot environment of the utility model embodiment is as follows: both played the fixedly effect of humidity-sensitive element 7 with humidity-sensitive element 7 contacted metal bolts 5, play again simultaneously the effect of wire, since in this humidity sensor without any welded structure, even if therefore be under the hot environment, can be owing to high temperature affects measurement effect and measuring accuracy yet.
Claims (1)
1. the humidity sensor that uses under the hot environment, the sensor housing (1) that comprises aluminum, it is characterized in that: the bottom of described housing (1) is bottom (2), the upper end offers opening (3), in opening (3), be provided with wire netting (4), cross-under has metal bolts (5) in bottom (2), the nut place, top of metal bolts (5) clamps by nut (6) humidity-sensitive element (7), and the top of humidity-sensitive element (7) copper electrode (8) inner with being fixed on housing (1) contacts.
