Objetivos

Acquire knowledge of industrial instrumentation by understanding the different primal elements associated with the conversion of the quantities. In particular, acquire the ability to select the different primal elements depending on the applications.

Describe the operation of the main constituents of a measuring instrument: transducer, signal conditioning circuit, indicator / logger and power supply.

Know the static and dynamic characteristics of a measuring instrument.

Know how to handle measuring instruments of physical / chemical quantities.

Understand the operation and advantages of pneumatic control systems used in industrial processes.

Describe the operation and pneumatic control elements known in the industrial context.

Understand and characterize the three actions of a Proportional, Integral and Derivative (PID). Learn to tune a PID controller using the Ziegler-Nichols rules.
