Sample executes inspection to sample.Due to the temperature and humidity difference inside and outside working space 82, under the conditions of certain Temperature Humidity Combinations, open
Chamber door or closing chamber door can cause the solidifying of the electrical position such as 1 sensing element of humiture transducer, 111 surface, pin and pick-up portion 12
Dew, in the state of energization, the condensation at electrical position and the dust of deposition can cause the resistance variations at electrical position and chemistry anti-
It answers, gently then causes measurement, control and display error, electrical erosion, open circuit or short circuit are then caused when serious and causes failure.This hair
Bright humiture transducer 1 is kept the temperature in pick-up portion 12 using humiture transducer thermal insulation casing 2, before can effectively reduce door opening or closing
Temperature difference and condensation risk inside and outside pick-up portion 12 afterwards；Even if condensation is inevitable under the conditions of extreme environment, sensing
The constant gas that 11 sensing element of portion, 111 surface is subjected to can avoid sensing element 111 and its pin after condensation in short-term immediately
Restore normal, so that condensation under extreme condition, which is effectively relieved, damages brought risk to electric components and sensing element 111.
Humiture test box is not the composite test for being only used as temperature and humidity, and many test specifications and application may only require temperature
Degree test；Humid test can not be used only for simulating mild ground environment simultaneously, also there is many test and application requirement
The severe local environment of simulation more has test requirements document simulated altitude and space such as the temperature environment on severe winter, heat, desert and plateau
Cosmos temperature environment, including extremely low temperature and quick temperature change.Especially aerospace and military project application field, high/low temperature
Ambient temperature range it is wider, temperature change is bigger, maximum temperature range (- 70~+180) DEG C, and maximum temperature rate is more than
15℃/min.And in practical application, the temperature condition of Temperature Humidity Combinations test is relatively mild, usually (5~75) DEG C it
Between.In view of above, the humiture transducer of humiture test box needs the environment temperature grade of pole wide scope, and price variance is outstanding
Very.Such as the humiture transducer of (- 30~80) DEG C range, the market price is only 180 yuan/, and (- 70~180) DEG C range
Humiture transducer, the market price are up to 2500 yuan/.Due to the price variance of great disparity, reliability is low and daily maintenance and
Replacement cost height etc., the reliability and user experience of humiture test box annoying always manufacturer and the user of relevant industries.
Based on temperature and humidity sensing device of the invention, the humiture transducer of common ambient grade can be used, it is only necessary to
When humid test, the dismounting of temperature and humidity sensing device only need to be by high/low temperature and quick temperature change including wide temperature range
Can, so that type selecting and deployment cost be effectively reduced and extend the service life of temperature and humidity sensing device.
Humiture test box needs to pass through the means realization simulation artificial environment such as heating, cooling, humidification and dehumidifying, and ventilation follows
Ring is to ensure that the primary condition that heat transfer and temperature and humidity are evenly distributed, however the pollutant from sample during testing, especially raw
Secretion, the excreta of species sample, medicament and nutrient solution of sample treatment etc., which are invariably constituted humiture transducer, to be polluted.When
When humiture transducer is fixedly mounted, the daily maintenance of humiture transducer is executed by user and is replaced almost impossible.This hair
Bright temperature and humidity sensing device is convenient to and humiture test box pair by the connector assembly of air sampling tube 5 and electrical connection section 13
It connects, not only can be convenient the daily maintenance of humiture transducer, can also quickly realize the replacement of temperature and humidity sensing device, it can
To be completed by operator.
Since temperature and humidity sensing device is located inside working space 82, humiture test box temperature and humidity reaches steady state
When, the temperature and humidity of temperature and humidity sensing device and its components, air sampling tube 5 and working space 82 is completely the same, such application
Scene, without using air sampling tube thermal insulation casing 6.
In view of above the problem of humiture transducer is fixedly mounted, even if being passed using the temperature and humidity of the mobile installation of method one
Induction device, severe environmental conditions of humiture test box working space 82, including temperature, humidity and irradiation etc. seriously affect electrically
The performance and reliability of components and safety, the measurement and control of temperature and humidity are seriously affected as irradiated, and irradiation influences rubber and plastic material
The durability of material, air sampling tube 5 and the dismounting of electrical connection section etc..Because the method one is using there are still exceptions, originally
Inventive method two can further solution one residue problem.
Method two in embodiment 1 specifically: temperature and humidity sensing device is fixed on to the exterior space of humiture test box,
Air is sucked by ventilation circulation system negative pressure mouth 811 in working space 82, by the pressurization of ventilation circulation system 81, is followed from ventilation
Loop system positive pressure mouth 812 is discharged, and it is logical to pass sequentially through air sampling tube 5, ventilation interface pipe 3131, both air flow modulation pipe 4, circle
Air holes 1121,111 surface of sensing element, rectangular ventilation holes 1122 are discharged into temperature and humidity examination finally by outside housing cover ventilation hole 321
Tryoff exterior space (Fig. 7).
The temperature and humidity sensing device of method two is located at any position of humiture test box exterior space, as side, the back side,
The exposed space of top surface or the concealed space around electric control system 83, specific location depend on humiture collection, maintenance, more
Change, install and appearance in terms of comprehensively consider.Since temperature and humidity sensing device is located at the exterior space of working space 82, Ying Caiyong
Air sampling tube thermal insulation casing 6 strictly keeps the temperature air sampling tube 5, it is ensured that the air inside working space 82 passes through air sampling
When pipe 5 reaches the surface of sensing element 111, it is not heated and cools down, temperature and humidity remains unchanged.When without carrying out humid test
And the range of humid test can pass through cutting air sampling tube 5 when having surmounted the applicable temperature humidity range of humiture transducer
Air flowing the harsh temperature and humidity conditions of simple realization isolation.The reason of can infering, cutting air sampling tube 5 are cut off simultaneously
The sampling of temperature and humidity, it is therefore desirable to extra gear temperature sensor meets such application scenarios, however temperature sensor
Humiture transducer of the deployment cost well below wide temperature humidity range.Since temperature and humidity sensing device is far from working space 82,
Irradiation in working space 82 will not influence the acquisition and control of temperature and humidity, thus method two is especially suitable has irradiation function
Humiture test box.
The air being discharged from temperature and humidity sensing device needs to add to the inside of working space 82 by certain channel
It can maintain the pressure balance of working space 82.The airtightness of general humiture test box working space 82 can not accomplish absolutely,
Namely the inside and outside possibility that there is leakage of working space 82, such as the axis hole of 81 motor of ventilation circulation system, the outlet of condensed water, humidification
Entrance, instrument connection, gasket, balance hole or the window for keeping pressure balance of device, mouth etc. of taking a breath.The air quantity as needed for temperature and humidity sensing device is very
Small, the channel of these leakages is enough to maintain the pressure balance inside and outside working space 82.
Embodiment 2: humiture test box has the scene for adjusting and requiring to circulation speed, and temperature and humidity sensing device also wraps
Mini-fan 9 is included, the mini-fan 9 includes mini-fan negative pressure mouth 91 and mini-fan positive pressure mouth 92, the mini-fan

The wind speed of high-low temperature test chamber is proved to be reasonable using other speed except the platform environment of equipment, and to prevent in test specimen
Other than the middle heat transmitting for generating the conjunction that do not conform to the actual conditions, the wind speed near test specimen should be no more than 1.7m/s, for test in itself,
Wind speed is the smaller the better, and wind speed crosses the heat exchange of air flow in conference accelerated test part surface and cabinet, for the true of test
Property is unfavorable；And the thermocycling standard of GB/T2423 then makes qualitative regulation to wind speed, it is as described below: 1) high-low temperature test chamber
In working space 82, for the temperature condition and tolerance for being able to maintain defined in this standard, it can be protected with forced air circulation
It is uniform to hold temperature；2) under no forced air circulation test situation, high-low temperature test chamber and test specimen size and its heat dissipation are always
Amount is sufficiently large by comparison, and " influence of free air condition " can be simulated by arriving greatly.3) height of forced air circulation is used
When temperature test box is tested, wind speed is as low as possible.
In order to guarantee the uniformity of temperature and humidity in humiture test box working space 82, in high and low temperature alternating humidity test chamber

This, for different test and application purpose, humiture test box is different to the limitation of wind speed.
At the same time, wind speed has an impact the time constant of humiture transducer, increases wind speed, and time constant speed becomes smaller.
For semiconductor type humiture transducer, the variation of wind speed seriously affects the flowing and heat exchange of air, to influence sensor
Steam is absorbed and released, wind speed is excessive, and temperature is relatively low, and humidity is bigger than normal；For wet and dry bulb humiture transducer, wind speed is direct
The water evaporation of wet bulb temperature sensor is influenced to influence the measurement accuracy of humidity.Due to the survey of air speed influence temperature and humidity
Amount, humiture transducer is demarcated under defined wind friction velocity by general humiture transducer manufacturer, or certain
Measurement and control algolithm are provided under wind friction velocity, thus require also to come according to the wind speed of regulation, such as 1m/s using warm and humid in application
Spend transmitter.It can be seen that other than in addition to testing and using strict requirements are proposed to wind speed, temperature and humidity measurement precision and control fluctuation
The stability and dynamic property of degree equally propose design requirement to wind speed.
