TIPS The Industrial Instrumentation.

 

 Basic Concepts Instrumentation is the science of measuring physical parameters, related to the control and automation of processes.  If something can be measured, then it can be controlled.

 

 

Process: The system that we are going to try to measure and control.  Process Variable (PV): Specific quantity that we are measuring in a process.  Setpoint (SP): The Target value, in which the process variable must be kept.  Primary Sensing Element (PSE): Device that measures PV and transforms the result into an analog signal.

 Transducer: Device that converts a standardized instrumentation signal into another standardized instrumentation signal.  Transmitter: Device that converts a signal produced by the PSE into a standardized instrumentation signal.  Ranges (High - Low): Process values ​​that adjust to 0% and 100% of the calibrated range of the transmitter.

 

 Zero and Span: Zero refers to the starting point of an instrument's range, and Span refers to the difference between (High Range - Low Range).  Controller: Device that receives the PV, compares it with the SP, and executes a corrective action, which is sent from an output signal to the FCE.

 

 Final Control Element (FCE): Device that receives the output signal from the controller and executes an action that modifies the process.  Automatic Mode: When the controller executes an output signal to match the PV with the SP.  Manual Mode: When the action that a controller executes, on the process, is ordered directly by a human operator.
