Heating and humidification system:

1. The heater adopts a porcelain frame nickel chromium wire electric heater, which has low thermal inertia and long service life. The instrument outputs a controllable pulse duty cycle PID signal, which is controlled by a solid-state relay for smooth and reliable control;

2. Steam boiler electric heating and humidification method, armored electric heating tube, PID control method, using non-contact periodic pulse width modulation SSR (solid state relay) control, equipped with water level control device, heater anti dry burning device;

Control system:

1. Temperature controller: adopts LCD touch screen temperature and humidity controller, which can set values and run programs;

2. Sensor: PT100 temperature sensor;

3. Solid state relay zero crossing triggering is used to control the heating output, in order to reduce noise, minimize pollution, facilitate maintenance, and improve control accuracy;

4. Safety protection measures should be installed in the control system, including phase loss protection, phase sequence error protection, fan overload protection, over temperature power-off protection, leakage protection, etc;

5. The control system is equipped with a user-friendly operation panel, located in the upper left corner of the test box, with power, lighting, and emergency stop button indicator lights;

6. In addition to the main controller, an independent overtemperature protector is also installed in the system. Even if the main controller fails, the overtemperature protector can reliably disconnect the heating power supply to protect the safety of the equipment and test samples;

7. An interlock device is installed in the electrical control system, which prevents the heating and humidification system from starting when the circulating fan is not started or overloaded;
