It is the branch of engineering which deals with the measurement, monitoring, display etc. of the several of energy exchanges which take place during process operations. “In short Instrumentation is the study of Instrument.”

 

Instrument:

Instrument is a device which is used to measure, monitor, display etc. of a process variable.

Instrumentation Question And Answer

                                                                                                                                                                                                                                                                                                       1. What is QA/QC?

Ans: QA/QC means, “Quality Assurance / Quality Control” The purpose of this (QA/QC) is to establish the sequence of requirement for the quality of material, quality of works, its inspection, and records.

                                                                                                                                                                                                                                                                                                                

2. What is the MMG Quality Control Management System?

Ans: ISO 9001 ~ 2000

 

3. What is the Quality Control?

Ans: Quality Control “Those activities and techniques used to achieve and maintain the quality of product, process or service”.

 

4. What is Quality Control Plan?

Ans: Quality Plan “Document Specification which procedures and associated resources shall be applied by whom and when to specific project, product, process or contract”.

 

5. What is non-conformity?

Ans: Non-conformity “Non-fulfillment of requirement”. (Complete failure of a system, or controls, which result in completely unsatisfactory goods or services being provided).

9. What is the basic required document for a QA/QC personal?

Ans: The basic required documents for a QA/QC personal are as following.

ITP (Inspection Test Plan): To conduct the quality check (Inspection of Witness, Surveillance and Hold Point) etc.

RFI: To conduct the inspection of completed work.

QR (Quality Record): To maintain the quality records of completed works etc.

10. What are QA/QC’s ITP and QCP? Give brief?

Ans: ITP: This procedure informs about the kinds of quality check (surveillance, inspection, witness or hold pints) means quality of works is being done in proper sequences.

 

QCP: This procedure addresses the activities and requirement in details
