About this app

Engineering Station – Industrial tools for PLC, 4–20mA signal conversion, calibration, and PID tuning.
Fast and accurate calculator for field engineers.
No setup required — instant results.

⚡ Signal & Process Calculation
Convert 4–20 mA ↔ Engineering Unit, PV, percentage, and process range values quickly.

📈 Calibration & Trend Analysis
Support calibration workspace for 4–20 mA and Free Scaling.
Input calibration points, compare actual vs reference, review linearity, error, best-fit curve, and trend analysis.

🔧 Recalibration / Drift Check Support
Useful for checking instruments that have been installed for a long time and may start showing inaccurate readings.
Helps evaluate as-found data, error, span deviation, and whether the issue may require recalibration, rescaling, zero trim, span trim, or DCS scaling check.

🌡 Thermocouple Calculator
Convert mV ↔ Temperature using ITS-90 reference with complete thermocouple types.

🧠 PLC Analog Tools
Raw ↔ PV conversion for Siemens and Allen-Bradley analog modules.

🎯 PID Tuning
Calculate P, I, and D parameters to support control loop optimization.

🧪 PID Loop Simulator
Simulate loop response, trend behavior, and tuning changes for learning and analysis.

🌊 Steam Flow Calculator
Calculate steam flow using DP flow principle with pressure and temperature compensation.

📄 Export & History
Save calculation history and export selected reports to PDF.

Engineering Station is designed to make technical work faster, cleaner, and easier directly from your phone.
