一, intelligent program temperature control instrument
※ Use
An intelligent programmed thermometer is a device used to precisely control temperature.
※ Working principle
1. Temperature signal acquisition: Built-in high-precision temperature sensor can sense and collect temperature information of the controlled object in real time, and convert temperature data into electrical signals to transmit to the controller.
2. Data processing and analysis: After receiving the temperature signal, the controller uses the built-in algorithm to process and analyze the temperature data, including comparing with the preset target temperature, calculating the error and determining the control strategy.
3. Control execution: According to the data processing results, output corresponding control signals, such as analog signals (4-20mA) or digital signals (such as PWM signals), drive heating, cooling or other temperature control equipment to perform corresponding operations to achieve temperature regulation and stability.
4. Feedback adjustment: real-time monitoring of temperature changes, according to the deviation of the actual temperature and the target temperature automatically adjust the control strategy to ensure the accuracy and stability of temperature control.
※ Functional Features
1. Intelligent control: it can automatically detect and adjust the temperature without frequent manual intervention. Some models have a self-learning function, which can automatically optimize control strategies based on historical data to adapt to different working conditions and needs.
2. High-precision temperature control: The use of high-precision sensors and advanced algorithms to achieve accurate temperature measurement and control, the control accuracy of up to 0.1 ° C or higher, to meet the requirements of high temperature control application scenarios, such as scientific research experiments, high-end industrial production.
3. A variety of control modes: usually have a variety of control modes, such as PID control, fuzzy control, etc., according to different controlled objects and control requirements to choose the appropriate control mode, in order to achieve the best control effect.
4. Data display and record: equipped with a display screen, real-time display of the current temperature, set temperature, operating status and other information. Some intelligent program temperature control instruments also have data recording functions, which can record temperature change curves, operation records, etc., which is convenient for users to perform data analysis and troubleshooting.
5. Alarm function: When the temperature exceeds the set upper limit or lower limit, failure and other abnormal circumstances, it can send an audible and visual alarm signal in time to remind users to take appropriate measures to ensure equipment and production safety.
Communication interface: Support a variety of communication interfaces, such as RS485, RS232, USB, Ethernet, etc., can communicate with computers, PLC and other equipment to achieve remote monitoring, data transmission and centralized management.
※Technical parameter
| Temperature control range |
Different intelligent program temperature control instrument temperature control range is different, generally common range from -100 ° C to 1250 ° C or even higher, such as Deli digital display electronic temperature controller measurement range of -20 ° C to 85 ° C, and ZWK-I-120KW intelligent program temperature control cabinet temperature range of 0 ° C to 1250 ° C. |
| Accuracy of temperature regulation |
The accuracy is usually up to ±0.1 ° C -±1 ° C, such as the artificial intelligence regulator temperature control accuracy of Hongrun company is basically up to ±0.1 ° C, and some household or ordinary industrial use may be ±1 ° C. |
| Operating voltage |
Generally 220V±5% VAC, 50Hz, there are some special models can be adapted to other voltage levels. |
| Rated working current |
According to different load capacity, common 16A, 30A and so on. |
