Description
Technical field
The present invention relates to measurement instrument, more particularly relate to a kind of intelligent bleeder hygrometer.
Background technology
In ambient condition parameter measurement technology, Humidity Detection is an important parameter.Common Humidity Detection instrument has psychrometer, hair hygrometer, dew-point hygrometer and humidity-sensitive elements such as utilization pottery, semiconductor to make the hygrometer of sensor at present.Wherein the temperature sensitive type hygrometer has simple in structurely, and so the advantage that measurement range is wide, but need add manual intervention processes such as water is generally should not be as the usefulness of on-line detector table.And humidity-sensitive element type hygrometer is convenient for installation and maintenance, can be used as the usefulness of on-line detector table, but because the situation that exists surface contamination to lose efficacy, so its serviceable life is short, high humidity area measure precision is low.In addition, the stated accuracy of instrument and actual measurement precision are also closely related with the airflow state of measuring point, and this is to need to solve in present Humidity Detection instrument and the moisture measurement technology and the technical matters that is not resolved as yet.
Summary of the invention
Technical matters: in order to overcome the deficiency that above-mentioned hygrometer exists, improve hygroscopic performance, solve the technical issues that need to address in present Humidity Detection instrument and the moisture measurement technology.The invention provides a kind of intelligent bleeder hygrometer.
Technical scheme: for achieving the above object, a kind of intelligent bleeder hygrometer of the present invention is by sampling pipe, intelligent object, show and the data output unit, instrument power, dry-bulb temperature sensor, the wet temperature sensor of asking, dynamic pressure transducer, mini fan, hygroscopic material, miniature ball-cock assembly, water receptacle, level electrode, the moisturizing kapillary is formed, pass respectively in the respective aperture that has at described sampling pipe upper wall dry-bulb temperature sensor is installed, wet bulb temperature sensor, and dynamic pressure transducer, pass at described sampling pipe lower wall and to have and to install wet asking in the corresponding hole of temperature sensor water receptacle is installed, in described sampling pipe right-hand member pipe, mini fan is installed, described wet bulb temperature sensor end is with hygroscopic material, this hygroscopic material afterbody is put into water receptacle, this water
Moisturizing kapillary and level electrode are housed on the container, and this moisturizing capillary end is equipped with miniature ball-cock assembly.
Beneficial effect: a kind of intelligent bleeder hygrometer of the present invention, the coupling of sampling pipe and mini fan can guarantee to flow through the gas velocity of wet bulb thermometer in its technical scheme, the measuring accuracy that this has not only improved hygrometer itself has also improved the science to tested gas sample.The humidity value that is calculated by intelligent object by dry bulb and wet bulb temperature sensor signal is based upon on the accurate and reliable calorifics theory basis, and its theoretical precision is self-evident.Because the hygroscopic temperature probe of a kind of intelligent bleeder of the present invention is not subjected to the influence of surface sweating, make it have good measuring accuracy again in high humidity regions.And compare with the hygrometer of moisture sensor, the situation that does not exist surface contamination to lose efficacy is so solved sensor short problem in serviceable life.
In addition, the miniature ball-cock assembly that is placed in moisturizing capillary end in the water receptacle can keep the water level of water receptacle automatically, thereby, not needing artificial recharge, this just provides necessary condition for long-term on-line measurement.
When making the instrument dehydration owing to other reason besides, the signal of level electrode can impel intelligent object to send alerting signal.If when making sampling air flow obstructed for a certain reason, the dynamic pressure transducer signal can impel intelligent object to send alerting signal.This has improved the hygrometer reliability of operation again greatly.
A kind of intelligent bleeder hygrometer of the present invention is compared with existing humidity measuring instrument and is had the following advantages:
1, measuring accuracy height, wide, the long service life of range ability.
2, on-line measurement for a long time is for the atmosphere control system provides technique guarantee.
3, automatic fault detects, the reliability height.
4, air current composition has improved accuracy and the science measured.
