The temperature control accuracy of the product adopts a 0.1 degree temperature control meter
Introduction to temperature control meter:
temperature controller
The fully digital temperature controller adopts a new fuzzy digital control theory and fully intelligent approximation method. When the temperature approaches the set temperature, the heating power is controlled by variable frequency power variation, avoiding temperature fluctuations and 'overshoot inertia', making the water bath temperature stable in a 'straight line', greatly improving the temperature control effect.
Control device:
1: Temperature sensor
Adopting the digital temperature sensor recently launched by DALLAS company in the United States, compared with traditional platinum resistance temperature sensors, it has high sampling accuracy, good linearity, high sensitivity, high resolution and * performance, avoiding the accumulation errors and environmental temperature drift caused by the intermediate links of operational amplifiers and AD analog-to-digital conversion. Its high performance is the guarantee of measuring water bath temperature accuracy.
2: Microprocessor:
As the most widely used high-performance microprocessor produced by Microchip in the world, its high speed and strong anti-interference ability were quickly adopted by people. Fuzzy control theory and powerful control software are the core and soul of the entire controller.
3: Power control:
Using digital frequency conversion chopper technology to increase heating power
The variation of 0-1200W is controlled by high-performance software to ensure that the power of the water in the water bath is equal to the supplementary power, achieving the ultimate thermal balance.
