Weighing apparatus.
In some embodiments, when the environment temperature of the second temperature sensor 126 detection is higher than mixing chamber temperature, master control
Mould group control the second fan 124, second of driving adjusts fan 123, opens the sucking that exhausting mode continues environmental gas and mixes
Chamber 12, at this point, the 4th temperature in mixing chamber 12 passes as the pressure in continuous sucking surrounding air mixing chamber 12 can become larger
Sensor 127 detects temperature and also begins to ramp up, and consequently reaches the temperature value of setting, then drives third fan 129, gas is allowed to start
Outlet reaches stable gas pressure, i.e., until third temperature sensor 131 is consistent with the 4th temperature sensor 127 detection temperature at this time
It passes in and out flow and air-out flow is constant, into flow stable state.It is incoming with each sensor signal into after flow stable state,
The signal gradually measured is actually detected target.
In some embodiments, it is higher than 0.01 DEG C of setting value or more when the 4th temperature sensor 127 detects temperature, at this time
Temperature drift, master control module are first gradually increased the opening degree of opening degree adjuster 121, and 12 temperature of mixing chamber gradually decreases down at this time
Close to desired temperature, the index then evaluated becomes the measured value fluctuating change of the 4th temperature sensor 127, in order to eliminate temperature
Fluctuation needs to adjust the revolving speed of the first fan 122 and then adjusts the inlet of cold air, and to keep temperature to stablize, fluctuation is stablized
0.005 DEG C, at this time it is believed that reaching the temperature stable state of mixing chamber；And then the fan for needing to adjust 16 third fans 129 turns
Speed guarantees that mixing chamber be in flow stable state, when to detect temperature consistent for third temperature sensor 131 and the 4th temperature sensor 127,
Reach the stable state of set-point temperature.
In some embodiments, when the 4th temperature sensor 127 detection temperature in mixing chamber is lower than 0.01 DEG C of setting value
More than, temperature is relatively low at this time, firstly, the reduction opening degree of master control module control opening degree adjuster 121, and then adjusts second
Fan 124, in the cold air unit time, the reduction of conveying capacity, the inflow of air hot gas, temperature are gradually gone up, are set when reaching
Definite value, evaluation index becomes the measured value fluctuating change of the 4th temperature sensor 127 at this time, needs to adjust to eliminate temperature fluctuation
The revolving speed of third fan 129 and then the gas output for adjusting cold air stablize fluctuation at 0.005 DEG C, need to adjust to keep temperature to stablize
The revolving speed of third fan 129 guarantees that mixing chamber is in flow stable state, when third temperature sensor 131 and the 4th temperature sensor
127 detection temperature are consistent, that is, reach the stable state of set-point temperature.
