Instrumentation Engineering

Struggling to connect instrumentation theory with what you see on a real plant? Instrumentation Engineering turns sensors, transmitters, control loops and calibration into clear lessons and hands-on calculators, so you understand process control and can solve field problems with confidence. Study offline, revise quickly and calculate instantly, all in one instrumentation engineering app.

⚙️ CORE FEATURES

✅ 492 lessons across 10 subjects
Learn Measurement and Instrumentation, Transducers and Sensors, Transducer Engineering, Circuit Theory, Digital Logic Circuits, Electronic Devices and Circuits, Linear Integrated Circuits and Electrical Machines, plus General and Advanced Concepts covering PLC, DCS, SCADA, control valves and flow, level, pressure and temperature measurement. Read markers and "continue reading" take you straight back to where you stopped.

✅ 34 interactive instrumentation calculators
Results update as you type, with charts, gauges and step-by-step working. Scale 4–20 mA signals with a NAMUR NE43 fault check, convert thermocouple (K, J, T, E, N, R, S) and RTD Pt100 readings, tune PID loops with Ziegler–Nichols, Cohen–Coon or Lambda and watch a simulated step response, size orifice and venturi flow, range DP transmitters, and work out tank volume, strain gauge, LVDT and Wheatstone bridge values.

✅ Practise for exams and interviews
Work through 300 instrumentation interview questions with clear answers, 15 MCQ practice sets with 150 questions, and 30 practical how-to guides on calibration, P&ID reading, loop checking and troubleshooting.

✅ Quick reference in your pocket
Look up 270+ terms in the instrumentation dictionary and 120+ engineering formulas with explanations. One search box finds any lesson or calculator in seconds.

✅ Comfortable to study anywhere
Lessons and calculators work offline. Choose a light or dark theme, adjust the text size, find words inside a lesson and save favourites for revision.

👥 WHO IS THIS FOR?

• ICE and EIE students: revise transducers, signal conditioning and control systems before an exam, then test yourself with MCQs and check answers with the calculators.

• Diploma and polytechnic learners: build strong basics in measurement, sensors and electronics with short, illustrated lessons you can read on the bus.

• Instrument technicians: convert 12 mA into process units, check a thermocouple reading at the terminals or estimate DP flow during a loop check, even with no mobile data on site.

• Job seekers and fresh graduates: prepare for instrumentation and control engineer interviews with 300 focused questions and answers.

💡 WHY CHOOSE INSTRUMENTATION ENGINEERING?

Many apps give you either theory or a single calculator. Here, lessons, calculators, MCQs, interview Q&A, formulas and a dictionary work together in one clean, modern design with dark mode and offline access. Every calculator shows its formula and working, so you learn the method instead of just copying a number.

❓ FREQUENTLY ASKED QUESTIONS

Q: Does the app work offline?
A: Yes. Lessons, calculators, Q&A, formulas and the dictionary are on your device. Only the Updates articles need internet.

Q: Can I use the 4–20 mA, thermocouple and PID calculators at work?
A: Yes, they are designed for quick checks and learning. For safety-critical designs, always confirm results against the applicable standards and manufacturer data.

Q: Does it cover PLC, DCS and SCADA?
A: Yes. The General and Advanced Concepts subjects explain PLC, DCS and SCADA alongside control valves, transmitters and process measurement.

Q: What does the Pro version add?
A: Instrumentation Engineer Pro is a separate one-time purchase with no ads, all 66 calculators, all 30 MCQ sets, study notes and save-as-PDF.
