Level Control Trainer Vocational Training Equipmen Teaching Model Process Control

1. Product Introduction
1.1 Product Description
The MR007P Level Control is a high-precision industrial-grade liquid level control device based on advanced PID control algorithms. It is designed for the field of modern fluid control and integrates high-sensitivity sensor detection, intelligent computing and processing, and precise actuators. It can achieve stable, reliable, and efficient liquid level closed-loop control of various liquid media.
This product adopts a modular architecture design. The core control unit is equipped with a Siemens S7-200 SMART series programmable logic controller (PLC), combined with a high-precision analog expansion module to ensure that the system can still maintain excellent dynamic response characteristics and anti-interference capabilities under complex working conditions. Through the external touch screen human-machine interface (HMI), users can intuitively set control parameters and monitor the liquid level change trend in real time, which greatly improves the convenience of operation and the visualization of the system.
As a multifunctional device that takes into account both teaching demonstration and industrial practice, its standardized interface design and open communication protocol can seamlessly connect to laboratory simulation platforms or small automated production lines, fully meeting the diversified needs of colleges and universities, scientific research institutes, and corporate R&D departments in process control teaching, algorithm verification, and system integration.
1.2 Product Features
1. Adopt adaptive PID algorithm to dynamically adjust the proportional, integral and differential parameters.
2. Siemens S7-200 SMARTPLC analog expansion module provides a stable and reliable control core, supports secondary development, and facilitates functional expansion.
3. Stainless steel pneumatic control valve + electronic differential pressure transmitter to ensure long-term stable operation, corrosion resistance and wear resistance.
4. The external touch screen displays key parameters such as liquid level, flow rate, valve opening in real time, supports historical data curve playback, and is convenient for experimental analysis.
5. With leakage protection circuit breaker to prevent electrical faults such as overload and short circuit.
