I&C Pro-Instrument Tools

I&C Pro is a comprehensive calculator toolkit built by a working power plant commissioning engineer, for instrumentation and control (I&C) engineers who work at the plant. No spreadsheets or reference tables — every calculation you need is one tap away. ■ 16 calculators across 7 categories [Loop & Signal] - mA → Set Value: Convert 4-20 mA current signal to process value - Set Value → mA: Convert process value to 4-20 mA signal - Square Root Converter: Linear ↔ √ mA linearization [Flow & Pressure] - DP ⇌ SCALE Converter: Between differential pressure and flow rate - O₂ Compensation: Compensate gas value by reference O₂ - Gas Unit Converter: ppm, mg/m³, %, mg/L [Temperature] - Thermocouple Converter: NIST-based T/C mV↔temperature (K, J, T, E, and more) - RTD Pt100 Calculator: Resistance↔temperature for Pt-385/Pt-392 (2/3-wire compensation) [Tank & Silo] - Tank Level Calculator: Cylindrical tank volume and level, drawn to the entered proportions - Silo Level Calculator: Cylinder+cone silo capacity, mass and estimated run time [Instrument Calibration] - Pressure Visualizer: Interactive absolute / gauge / vacuum / atmospheric relationship, live comparison across 11 pressure units - Chemical Tank Level Tx Verification: 22 water-treatment chemical presets (HCl, H₂SO₄, NaOH, N₂H₄, NH₄OH and more), temperature correction, transmitter verification and diagnosis - Level Compensator: Heater and drum level density compensation (new) [Vibration] - Vibration Converter: Displacement-Velocity-Acceleration for rotating machinery (Bently Nevada mils/ips ↔ ISO mm/s, RMS/0-p/p-p) - Disp Probe Gap & Simulation: Displacement probe gap calibration, VMS signal simulator, sensor library, DXD gap setting [Utility] - Percentage Calculator: Percentage, increase and decrease ■ Level Compensator — the heart of this release Saturated water and steam change density sharply with pressure, so a DP level transmitter does not read the true level without density compensation. Level Compensator computes the difference. - Two DCS algorithms: Siemens T3000 LEVEL block (ID 605) and Emerson Ovation LEVELCOMP - Four vessels: HP heater, LP heater, flash tank, HRSG steam drum — each with its own schematic - Built on IAPWS-IF97 steam tables (Regions 1/2/4) - Enter DP, mA or a sight-glass reading — the signal chain resolves either direction - Gauge-glass density correction, shown as a reference for how low the glass reads - DCS zero offset, alarm setpoints, and display end-stop handling - Per-project configuration profiles Verified against real plant operating data — from 1 bar to 200 bar, across two DCS vendors, including a full day of 2880 samples. ■ Key features - Fully offline — works inside plant networks with no connectivity - Live calculation — results update as you type - Guidance panel on every calculator — purpose, inputs, formula and field tips - 10 languages — English, 한국어, Tiếng Việt, Bahasa Indonesia, 中文(简体), العربية, Español, Français, Português, Русский - Project profiles — save and recall setups on the configuration-heavy calculators - Grounded in real field work — used on site by the engineer who wrote it ■ Who it is for - Power plant commissioning engineers - Instrumentation and control staff at refineries and chemical plants - Instrument maintenance and calibration technicians - Nuclear, thermal, combined-cycle and solar generation professionals - I&C students and instructors Built by a field engineer, for field engineers.
