Industrial Instrumentation and Process Control
Pressure, level, flow and temperature measurement, switches and sensors, 4-20 mA loops and the calculations, control valves, P&IDs, HART and smart transmitters, calibration, and how instruments meet the PLC, DCS and SCADA.
What you will learn
Explain instrumentation and control, describe the working principle of the common pressure, level, flow and temperature instruments, wire and read switches and proximity sensors, explain and calculate 4-20 mA loops both ways, describe control valves, actuators, positioners and I/P converters, read a P&ID, explain HART and Foundation Fieldbus, describe calibration and its records, and place every instrument in the PLC, DCS and SCADA loop.
- Tell open-loop from closed-loop and name every part of a control loop
- Explain absolute, gauge and differential pressure and the instruments that measure them
- Choose a level and a flow technology for a service and say why
- Read RTDs and thermocouples and check them with a meter
- Wire PNP and NPN sensors and limit switches to a PLC
- Calculate 4-20 mA to percent to process variable in both directions, including square-root flow
- Describe control valves, positioners, I/P converters and solenoid valves
- Read a P&ID, explain HART, describe calibration and follow a signal from field to screen

A shareable EDWartens certificate
Finish every module and pass the final assessment, and you can buy a certificate for ₹700. It carries a unique verification code on a public page anyone can check, so it stands up when a recruiter looks it up.
- Add it to your LinkedIn profile in one click
- Link it from a CV or portfolio, the URL is permanent
- Publicly verifiable by code, not a PDF anyone can edit
- Issued by EDWartens India, the training centre itself
The course itself stays free whether or not you ever buy one.
Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.
- Questions answered in the context of the module you are on
- The same engineers who teach the AEP programme
- Career tools, CV help and public job listings included
- Your progress and notes stay in your account for good

Common questions
Do I need any equipment?
No. A multimeter and any 4-20 mA transmitter or a loop calibrator make the loop modules hands-on, but every practice task can be done on paper.
Is this for engineers or technicians?
Both. Technicians get the principles behind what they wire and calibrate; engineers get the field reality behind the P&ID. The calculations module is the one interviewers ask about.
Which industries does this apply to?
Oil and gas, power, chemicals, pharma, water, cement, food and any plant with a control room. The instruments and the 4-20 mA loop are the same everywhere.
Some source lessons are short animations. Is that enough?
The animations show the principle in two minutes, and the notes and practice tasks add the depth: ranges, wiring, failure modes and the calculations.
Is the course really free?
Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.
What certificate do I get, and is it a vendor qualification?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not an ISA, vendor or government credential and is never described as one.
