Sensors 101: understanding sensors within a fluid control system
In the world of fluid control systems today, very little can be achieved without the raw data supplied by sensors, which need to be carefully specified to ensure that they are suited to their application. These sensors can help facilitate a variety of tasks from displaying process information and performing control functions to operating alarms, but each one has to communicate information to a process controller. Kieran Bennett, of process control specialist Bürkert, looks at the range of sensors available, the different technologies used in their design and how the application affects the specification.
