Humidity and heat resistant aging chamber
1. Performance specifications:
1, temperature range: room temperature -+85ºC
2, humidity range: 40-98%RH
3, temperature and humidity control accuracy: ±1.0ºC; ±2%RH
* Note: The performance guarantee of # 2-4 above should be measured after 30 minutes of stability with temperature sensing.
4, temperature and humidity distribution is uniform: ±2.0ºC; ±3%RH
* Note: The performance guarantee of the above # 5 items needs to be measured at 1/6 position of each wall in the test area and measured after 30 minutes of stable temperature and humidity.
5. Power supply: 220V
2. system structure:
1.electronic system (safety protection system) :
a Zero crossing thyristor power controller 2 sets (one for each temperature and humidity)
b Air-burn prevention switch 2 sets.
c Water shortage protection switch 1 group.
d Compressor high pressure protection switch.
e Compressor overheat protection switch.
f Compressor overcurrent protection switch.
g Two fast fuses.
h No fuse switch protection
i line fuse and fully sheathed terminals.
j Water shortage alert.
2.Air duct system
a Made of table 90W extended stainless steel core.
b Multi-wing Chalcosaurus speed up the amount of heat and humidity circulation.
3.heating system: scale type stainless steel humidifier pipe.
4.humidification system: EL type stainless steel humidification pipe.
5. temperature sensing system: stainless steel SUR304Pt100 two dry and wet sphere comparison input through A/D conversion temperature measurement humidity.
6. Water system:
a built-in stainless steel water tank 20L1.
b Automatic water supply device (pumping water from the lower level to the upper level).
c Water shortage indication alarm.
7.Manufacturing system
The control system adopts P.I.D controller, temperature and humidity are controlled simultaneously.
a Controller specifications:
Accuracy: Temperature ±0.1ºC+1digit, humidity ±3%RH+digit.
With upper and lower limit standby and alarm function
Temperature and humidity input signal PT100×2 (dry ball and wet ball).
Temperature and humidity change output: 4-20MA.
6 groups of P.I.D control parameters set P.I.D automatic calculation.
Dry and wet ball automatic correction
b Control function
With reservation start and shutdown function
Date and time adjustment function.
8.Box material
Inner box material: SUS# 304 mirror stainless steel plate
Outer box material: 304 stainless steel.
Insulation material: PV rigid foam + glass wool.(YNMT)·
3. the working principle:
1.balanced temperature and humidity control system, with PID control SSR, so that the heating and humidification of the system is equal to the heat and humidity loss.
2.the dry and wet ball temperature measurement signal through A/D conversion input controller CPU and RAN output to the I/0 board, I/0 board issued instructions, so that the air supply system and freezing system work, while PID control SSR or heating SSR work, or humidification SSR work, so that the heat and humidity through the air supply system uniform test box to achieve balanced temperature and humidity regulation.
