Indicative Content |
Measurement Terminology
Definition and explanation of terms used for instrument specification and to quantify the quality and reliability of measurements taken. Significance of process variable measurement to the overall production process and the ethics involved in measurement and control.
|
Pressure Measurement
Pressure Basics; Nature of pressure, types of measurement (absolute, gauge and differential). Measurement Principles; elastic deformation and liquid column. Practical Implementation; manometers, diaphragm, Bourdon tube etc. Pressure Switches and Transmitters (Smart & Dumb). The mA analogue current transmission loop. Installation and application. Precautions and ancillary equipment.
|
Level Measurement
Level Basics; definitions, nature of level, vessel designs, volume, contents (liquids/solids). Measurement Principles; hydrostatic, capacitance, ultrasonic and radar techniques. Practical Implementation. Level Switches. Installation and application.
|
Flow Measurement
Flow Basics; definition, type of flow measurement. Measurement principles; differential pressure, velocity, temperature, density. Practical Implementation. Installation and application.
|
Temperature & Heat Measurement
Temperature Temperature scales. Process issues specific to temperature measurement. Measurement Principles; expansion, bimetallic, resistance change, thermo-voltaic, Practical Implementation; RTDs, thermocouples etc. Thermostats. Installation and application.
|
Calibration
Calibration Principles including ethical consideration in instrument data collection, terminology, procedures, precautions, standards, limitations, documentation and scheduling. Solve linear equations to calculate instrument output in units and percentage of range along with percentage error for given process conditions. Individually and as part of a group carry out practical bench calibration on typical industrial pressure, level and temperature measurement instruments and collaboratively develop calibration procedures for wet (field) calibrations.
