Why Controls &
Instrumentation?
To monitor/record/control various parameters
like
Pressure,Differential pressure
Temperature,Differential Temperature
Flow (Solid,Liquid,Gas)
Level ,Vibration,Speed
Electrical parameters like volt,Amp,power,PF
To generate Alarms / Trip in case of abnormal
conditions.
3. Dr.R.Jayapal
Facilitate data analysis
Facilitate automatic control of various
parameters.
Remote monitoring & operation
Interface with ERP for MIR
Ensure equipment and operating
personnel safety.
4. Dr.R.Jayapal
ELECTRICALS
To provide Drives for Mechanical
Equipment
To feed & control Power to various
equipments
To facilitate starting and stopping of
various equipments in sequential way
