Instrument Toolbox vs My LoopCal

Industrial Control & Instrumentation Toolbox - Your Smart Industrial Calculator A professional calculation toolbox designed for industrial control, automation, and instrumentation engineers. Whether for field debugging or engineering design, it helps you quickly complete various professional calculations. Core Features: PPM to mg/m³ Converter: Gas concentration unit conversion, supports custom molecular weight, built-in quick selection of common gas molecular weights, with environmental temperature and pressure compensation Unit Converter: Covers easy conversion of industrial measurement units including: Pressure (8 units including MPa, kPa, bar, psi, etc.) Volume Temperature Length Mass Saturated Steam Calculator: Input temperature to obtain saturated steam pressure, or input pressure to calculate saturated steam density, meeting steam system design requirements Flange Level Migration: Supports single/dual flange level calculations, with inputs for medium density, flange distance, and other parameters for precise level measurement calibration Pipeline Flow & Velocity Calculator: Applicable for both gas and liquid media, integrates velocity calculation, flow calculation, and diameter calculation, incorporating temperature, pressure, and other operating conditions Key Features: Clean and intuitive interface, easy operation Real-time calculation results Supports standard and operating condition conversions Built-in reference values like standard atmospheric pressure Suitable for both field engineering and design office scenarios This app is an essential professional tool for industrial automation, significantly improving engineering calculation efficiency. Target Users: Automation Engineers, Instrumentation Engineers, Process Engineers, Equipment Engineers, and other industrial control professionals.

LoopCal turns a 4–20 mA loop check into a calibration worksheet you can hand over, and it is the quickest way to convert a signal in the field. Built for instrumentation and calibration technicians. Fully offline. FROM CHECK TO WORKSHEET • Guided three-point, five-point, and custom 2–21-point checks • As-found and as-left runs, with the error and pass/fail at every point • Up-scale and down-scale readings with hysteresis • Tolerance as percent of span, signal units, or engineering units • Worst point and maximum error summarized for you • A clean PDF worksheet with your company name and logo, in US Letter or A4, plus CSV for your records CONVERT IN SECONDS • 4–20 mA, 0–20 mA, 0–10 V, 1–5 V, and your own custom signal endpoints • Direct-acting and reverse-acting ranges • Linear and square-root (flow) transfer functions • Engineering ranges with any unit, including negative and offset spans • Percent, signal, and engineering values update as you type, with the substituted formula shown • Verify this loop: take the range you just entered straight into a check EVERY INSTRUMENT ON RECORD • Save instruments with their ranges and calibration history • See what is coming due, and get a reminder before the next calibration • Reopen a saved instrument and start its next check without retyping the range LOOP POWER MATH • Shunt resistor voltage drop • Required supply voltage and remaining compliance • Maximum loop and wire resistance PRIVATE BY DESIGN • Everything runs on your device. No account, no ads, no tracking, no network. LoopCal is a calculation aid and field worksheet — not a calibrator, an accredited calibration service, or a replacement for manufacturer procedures. Always follow site lockout/tagout, operations authorization, device manuals, and approved procedures. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
