Control system:
Imported from Korea, all Chinese LCD 7 “LCD touch panel, drawing face to talk input data, temperature and humidity can be programmed at the same time, curve display, set value / display value curve. It supports the direct export of temperature and humidity record data by U disk, and can display various alarms respectively. When the fault occurs, it can display the fault on the screen to eliminate the fault and misoperation. Multi group PID control function, precise monitoring function, and display on the screen in the form of data.
Controller specification:
1. Accuracy: temperature ± 0.1 ℃ + 1digit, humidity ± 1% RH + 1digit
2. Resolution: temperature ± 0.01, humidity 0.1% R.H
3. With upper and lower limit standby and alarm functions
4. Temperature and humidity input signal selection PT 100 Ω× 2 (dry bulb and wet bulb)
5. Temperature and humidity conversion output: 4 ~ 20mA
6. Six groups of P.I.D control parameter setting, P.I.D automatic calculation, dry and wet bulb automatic correction
