Computerized Pressure Control Trainer
Product Code : EL-MAILE-10803
Quick Answer: The Computerized Pressure Control Trainer is a closed-loop process control trainer that demonstrates industrial pressure control using a 2nd order air pressure system. It comprises two in-line pressure tanks (10L capacity each, rated to 10bar, operated at 6bar) interconnected by a flow control valve, with an additional air-tapping valve on the second tank available to simulate a disturbance variable; a pressure sensor (0…6bar) measures the pressure in the second vessel, and a digital industrial controller drives a pneumatically operated control valve (DN15, Kvs 0,1m3/h, 4…20mA reference signal) to regulate it. 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, giving a practical, industry-realistic introduction to control-engineering fundamentals via a freely configurable P, I, D digital controller.
The air pressure control system is a 2nd order system that comprises two in-line pressure tanks interconnected by a flow control valve; an additional valve on the second tank makes air tapping possible and so can be used to simulate a disturbance variable, while a pressure sensor measures the pressure in the second vessel. The controller used is a digital industrial controller, and the actuator in the loop is a pneumatically operated control valve with a standardized current signal input. 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.
