I&C Pro-Instrument Tools

15 offline calculators for Power Plant I&C engineers. 4-20 mA, RTD, thermocouple, vibration, displacement probe, chemical tanks — every calc you need on site.

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.

■ 15 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]
