Analogue control systems
Illustrated Guide to Mechanical Building Services 3rd Edition (BG 31/2017), written by David Bleicher and published by BSRIA in May 2017, in relation to analogue control systems it states: ‘Pneumatic systems are little used today. Sensors control the position of pneumatic actuators on valves and dampers by means of compressed air. Pneumatic actuation can be combined with modern DDC controllers to provide a hybrid control product for applications that require fast response, for example the control of fume cupboards. Electric systems provide analogue control and in general are unable to communicate with each other. However, they provide a simple, robust method of control for many basic applications. They provide control by varying the voltage/current to electric actuators on valves and dampers.’
