FLTP Process Control Multivariable System Didactic Equipment Process Control Trainer
The system mod. FLTP has been developed to cover the following educational subjects included in an intense theoretical-practical training program, as follows: Study of the sensors and relative signal conditioners circuits for the process variables: Flow, Level, Temperature and Pressure. Study of the closed ring process control techniques. Study of the different process control ways: PID control with PLC, with Industrial PID controller, with PC data acquisition card and with datalogger. The system mod. FLTP has been carried out according to industrial criteria and with real industrial components. It is composed of the following elements: Process unit mod. FLTP-U with the following sensors: Temperature: (Pt100, thermocouple-type J, PTC and NTC) Level: (piezometric and ON/OFF sensor ) Flow: (turbine-type and ON/OFF magnetic sensor) Pressure: (piezometric and ON/OFF sensor) Control unit including: Signal amplifier modules Signal coupling circuits for the control of: temperature mod. FLTP-B, level and flow mod. FLTP-C and pressure mod. FLTP-D. Training program The system mod. FLTP allows the theoretical analysis and the experiments on the following subjects: • Detection of the characteristic curve of the transducers and the signal conditioning circuits for the temperature, flow, level and pressure sensors. • Detection of the time constants of the processes. • Analysis of the closed ring automatic control for flow, level, temperature and pressure: ON/OFF control mode and Proportional (P), Proportional Integral (PI), Proportional Derivative (PD) and Proportional Integral Derivative (PID) control mode. • Analysis of the variables curves through the PID algorithm in the PLC, in the industrial PID controller (with autotuning function) and acquisition/control card for PC with dedicated software (supplied).
