Description
RT 682 Multivariable Control: Stirred Tank Didactic Equipment Vocational Training Equipment Thermal Trainer

Heated stirrer tank with heat recovery as model: coupled level and temperature control
Features
- practical multivariable control of temperature and level in a stirred tank
- typical application from process engineering with heat recovery
- two configurable industrial controllers
- optional process control software RT 650.60 available
Learning objectives/experiments
- coupled level and temperature control
- level control with
-- PI controller
-- feedforward control
- temperature control
-- with two-point controller
-- with three-point controller (split range)
-- with override control
-- via motorised valve with position feedback
- plotting step responses
