HRS-303 Process control trainer

Equipment Overview

This equipment is a comprehensive experimental system for process control and automation instrumentation developed to meet the needs of school teaching and engineering practice platform. The device embodies the concept of engineering, emphasising engineering, practice and openness, which can not only complete the opening of relevant course experiments, but also be a platform for students to carry out engineering training, graduation design and course design. At the same time, it can also carry out engineering training and technical practice. The device system covers the knowledge of the course: process control; automation instrumentation and detection and sensing devices; automation instrumentation network communication.

Functional characteristics

1. Process control process experimental object for the miniature a production process process object, the production process process object to have the following characteristics:

 industry's four commonly used thermal parameters: temperature, pressure, flow, level representative of the engineering detection and sensing transmission devices, commonly used engineering actuators (control valves, inverters, SCR phase shifter regulators) can be reflected on it.

* Process objects can be steadily realised from single-loop, series, feed-forward-feedback, ratio, composite control and other experiments.

* PID, hysteresis, coupling control algorithms and regulation algorithms can be verified on it.

*Experiments in the use and calibration of automation instruments.

*Composition of control system can be reflected on it.
