Computerized Level Control Trainer
Product Code : EL-MAILE-10802
Quick Answer: The Computerized Level Control Trainer is a closed-loop process control trainer that demonstrates industrial level control using real control-engineering components. A centrifugal pump (250W, 150L/min, 7m head) delivers water from a 30L storage tank into a transparent 7L level-controlled tank, where a pressure transducer at the tank's base measures the liquid level (0…0,6m, 0…100mbar) and a digital industrial controller drives a pneumatically operated control valve (DN 20, Kvs 4,0m3/h) fitted with an electro-pneumatic positioner to regulate it, while a ball valve in the outlet line introduces defined disturbance variables. The controlled variable X and manipulating variable Y are plotted on an integrated 2-channel line recorder or tapped as analogue signals at switch-cabinet lab jacks for connecting external recording equipment such as an oscilloscope or flatbed plotter, with optional process control software available, giving a practical, industry-realistic introduction to control-engineering fundamentals via a freely configurable P, I, D digital controller.
A pump delivers water from a storage tank to the transparent level-controlled tank, and the liquid level is measured by a pressure transducer installed at the base of the level-controlled tank. The controller used is a digital industrial controller, and the actuator in the control loop is a pneumatically operated control valve with an electro-pneumatic positioner; a ball valve in the outlet line enables defined disturbance variables to be generated. The controlled variable X and the manipulating variable Y are plotted directly on an integrated 2-channel line recorder, or alternatively the variables can be tapped as analogue signals at lab jacks on the switch cabinet, which enables external recording equipment, such as an oscilloscope or a flatbed plotter, to be connected; process control software is optionally available.
