Description
Technical field
The utility model relates to the humidity detector of the complex area such as building ground, traffic reason.
Background technology
In order to detect gas with various humidity under the present circumstances or concentration value, different monitors must be adopted to detect.For example, building ground circumstance complication, dust pollution is large, generally can there is dust in air, cause working sensor state labile, be placed in outdoor probe for a long time and easily damage, cause measurement out of true, how comprehensive above-mentioned features, ensure the on-line measurement steady in a long-term of moisture, become the difficulties in industry under complex dielectrics environment.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of structure simple, long service life, effectively prevents probe wearing and tearing, and the interference of extraneous rainwater, the humidity measurement instrument that measuring accuracy is high.
For realizing the utility model object, provide following technical scheme: humidity measurement instrument, comprise control box, the hollow feeler lever be connected with control box, be arranged at the moisture probe of feeler lever end, moisture probe is connected with the testing circuit in control box through feeler lever by transmission cable, it is characterized in that moisture probe is provided with protective cover, described protective cover comprises the cylinder shell of one end open, openend is provided with end cap, casing center is provided with central tube, central tube surface offers bleeder vent, drying medium is filled with between central tube and housing, rotatable inner sleeve is socketed with in described central tube, rotating inner sleeve one end stretches out outside housing, external part is processed with air admission hole, the other end offers the venthole be interlinked to the outside with housing, moisture probe is plugged in and rotates in inner sleeve, moisture probe end is just to air admission hole, described air admission hole surface is provided with one deck filtering membrane.
As preferably, central tube inside surface is provided with one deck wearing layer.
As preferably, rotate between inner sleeve and central tube and be provided with ball.
The utility model beneficial effect: can the protective cover of filtering gas by arranging one for moisture probe; the data that humidity detection instrument is detected are more accurate; and not by the restriction of condition, under complex dielectrics environment, still can ensure the on-line measurement steady in a long-term of moisture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
