The instrumentation applied to the Naval sector involves the reliable reading and control of the parameters measured by any of the sensors installed in the different systems or processes of said sector.

In the processes it is absolutely necessary to control some magnitudes, such as pressure, flow, level, temperature, etc.

The control system can be defined as one that compares the value of the variable or condition to be controlled with a desired value and carries out an automatic corrective action according to the existing deviation.
