Process Control Instrumentation Engineering Interview Questions
We Discuss about Process Control Instrumentation Engineering Interview Questions and answers useful to prepare for the job interview. Process Control
High Reliability of Safety Instrumented Systems
Instrumentation safety may be broadly divided into two categories: the safety hazards posed by malfunctioning instruments, and special instrument systems
Instruments Calibration Procedures
Calibration refers to the adjustment of an instrument so its output accurately corresponds to its input throughout a specified range.
Control Valve Sequence Methods
In Control Valve Sequencing, for example, both control valves received the same pneumatic signal from a common I/P (current-to-pressure) converter.
Different Types of Flow Elements
Different Types of Flow Elements or Flow Sensors are Pitot tube, Annubar flow element, orifice, venturi, flow nozzle and Differential Pressure Flow Sensors.
Industrial Applications of Chromatographs
Since process chromatographs have the ability to independently analyze the quantities of multiple species within a chemical sample, these instruments
Selector Control Functions
In the broadest sense, a “selector” control strategy is where one signal is selected from multiple signals in a system
Limit Controls : High Limit & Low Limit Functions
A common application for select and limit functions is in cascade control strategies, where the output of one controller becomes
