Control and instrumentation, in fact, constitute the knowledge of industrial automation knowledge. Measurement and control of physical parameters control an industrial process such as temperature, pressure, surface, current, etc. Instruments and instruments required for measuring, transforming, transmitting and recording physical parameters are called precision instruments. In general, control knowledge and instrumentation are divided into two general categories:
In the first category, the segmentation of equipment is based on the type of operation performed on the variables:
Meter, Meter, Indicator, Transmitter, Controller and Recorder.
In the second category, the segmentation of equipment is based on the type of parameters in which various operations are performed on it:
Pressure, Temprerature, Level, and Flow
