Product details
Xmt-9000 series intelligent fuzzy liquid crystal controller
Product features: there is no bad temperature control, and it should be selected in case of temperature control problems
1、 Scope of application:
Xmt-9000 series intelligent fuzzy liquid crystal controller adopts large screen liquid crystal display and the latest intelligent fuzzy control technology, which can effectively suppress the influence of various disturbances. Whether it is the first overshoot suppression in the process of temperature rise or the restoration of artificial disturbance in the process of temperature rise, its inhibition performance is incomparable with that of traditional P and D control. It is suitable for the temperature control of electric drying, electric constant temperature, constant temperature water tank, bacterial culture, biochemical culture, constant temperature and humidity and other equipment. Its improved self-tuning PID algorithm can ensure that the temperature of the instrument and equipment rises rapidly and the overshoot is very small (or no overshoot), without manual readjustment of P and D data. It is your ideal temperature controller.
Combined with Chinese characteristics, a hierarchical fool menu is adopted. After the instrument is powered on for the first time, as long as you press the at key, the instrument will automatically adapt to the physical performance of the controlled object, and automatically adjust the parameters so that you can easily obtain satisfactory temperature control effect.
Ultra thin structure, wide viewing angle, high back and bright display make the meter reading as clear as white clouds in the blue sky.

LCD digital temperature controller anti overshoot instrument instructions
In the case of high temperature control accuracy and high temperature overshoot, the instrument can achieve better results.
1. First, set the measuring range of the instrument (consistent with the controlled object).
2. The self-tuning is carried out at the golden section point accessory of the measuring range (measuring range multiplied by o.618). (for objects of the same specification, only one self-tuning is needed.) for self-tuning, press do key for 10 seconds, PID self-tuning symbol will appear on the LCD screen, and the symbol will disappear automatically after self-tuning.
3. Press the set key for 10 seconds to enter the C menu. There are four items: HL, out -, ℃, FN. Observe out - to know the maximum output power of the set temperature at the golden section point. (example: out - = 61%).
4. From the end of the setting, enter the B menu and record the value of fright. When the temperature is stable, press up key to observe the actual power consumption at the golden section point. If the temperature overshoot requirement is not high, the actual power consumption should be 1 / 5.1/2 of the maximum output power.
5. If it does not meet the above requirements, you can enter FN in the C menu, which is the amplification factor. Changing it can change the maximum output power, so that it can meet the above requirements and achieve the ideal temperature control requirements.
6. If the measuring range is very small (for example, 60 ℃), and the set temperature is close to the ambient temperature (for example, the ambient temperature is 30 ℃, and the set temperature is 37 ℃), you can enter the C menu at this time: ℃ and set it as room temperature minus 5 ℃, that is, 30-5 = 25, which should be set as 25 ℃. In this way, the ideal temperature control effect can be achieved.
7. In the future, for equipment of the same specification, as long as the range, P, I, FN, and ℃ parameters are input, everything will be OK
