TT&C system
1. Temperature measurement: PT100 Platinum resistance.
2. Control device: use the intelligent digital temperature controller.
Temperature control mode: automatic set two-bit PID control.
Temperature setting mode: make the digital setting in the controller.
Temperature display mode: the set temperature and the measured temperature are displayed in the controller.
The product has a self-setting function to ensure that the temperature is constant at each set point.
The product has a linear compensation function to avoid the inconvenience of display errors.
3. The product is separately equipped with an over temperature protection instrument, which is used to set the upper limit alarm of the working temperature to prevent the damage caused to the test product and Test Chamber due to failure.
4. Operation mode: constant operation.
Environmental Chamber
Safety Precautions:
1. Over temperature protection setting: triple over temperature protection setting
2. Set temperature of the over temperature dial = set temperature + 15℃. When the temperature in the box is out of control and exceeds the set temperature of the over temperature dial, the buzzer in the box alarms, the box is in standby state, and should be reused after manual reset.
3. Over temperature alarm of the controller: when the product in the box continues to heat up and exceeds the temperature set by the internal parameters of the controller, the buzzer in the box will alarm, which should be manually reset and then reused.
4. The third level of protection is controlled by the anti-dry burning protector. When the heating pipe is uncontrolled and continuously heated, the anti-dry burning protector senses the temperature and then transmits the signal to the controller for alarm.
5. Phase sequence protection: the reverse phase connection or the missing phase connection of the main power supply is detected, and the device stops running
6. Humid air burning protection switch
The humidity generator can generate humidity normally during operation and has the function of avoiding air burning. The humidity air burning protection switch on the machine switchboard is adjusted to between 250-300℃ to maintain the normal operation of the humidity generator.
