Title:Control and Instrumentation
Long Title:Control & Instrumentation
Module Code:CHEP7004
Duration:1 Semester
Credits: 5
NFQ Level:Intermediate
Field of Study: Chemical & Process Eng
Valid From: Semester 1 - 2018/19 ( September 2018 )
Module Delivered in 1 programme(s)
Next Review Date: April 2023
Module Coordinator: NIALL MORRIS
Module Description: This module introduces students to fundamental aspects of both mathematical modelling as well as a wide variety of industrial instrumentation, including the valves and the controllers that are needed to form simple feedback loops. In addition, students learn how to interpret and draw piping and instrumentation diagrams based on industry standards.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Study, analyse and specify the instrumentation and on-line analytical equipment that is commonly found in the process industries.
LO2 Interpret, critique and develop Piping and Instrumentation diagrams commonly used in the process industries.
LO3 Interpret, analyse and develop the basis of mathematical modelling in connection with the unsteady-state behaviour of processes, then identify, analyse and select the basic elements needed to form a simple feedback control loop.
LO4 Manipulate dynamic simulation software to study and analyse the unsteady-state behaviour of open-loop processes.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).

Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
Co-requisite Modules
No Co-requisite modules listed

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
