Quick guide

How to use this calculator

  1. Choose the comparison, calibration, scaling, resolution, or uncertainty model that matches the measurement record you actually have.
  2. Enter reference values, indications, ranges, specification components, distributions, and units exactly as documented; the calculator exposes the intermediate relationship instead of hiding it.
  3. Use the companion outputs to reconcile the worksheet, then retain the stated metrology boundary. A numerical result is not a calibration certificate, traceability statement, adjustment instruction, or conformity decision.

Calculation method

How the linear sensor and signal scaling calculator works

Convert the signal a visitor actually has into the process value they need without hiding live-zero, span, unit, or out-of-range assumptions.

Fraction of span = (query − source low) ÷ source span. Destination value = destination low + fraction × destination span. Presets supply only signal endpoints; process endpoints always remain visitor-entered.

Worked example

Linear Sensor and Signal Scaling example

A 4–20 mA signal mapped to 0–250 units gives 125 units at 12 mA and 50% of span.

Fraction of span = (query − source low) ÷ source span. Destination value = destination low + fraction × destination span. Presets supply only signal endpoints; process endpoints always remain visitor-entered.

Supported inputs

Precision and limits

Measurement and calibration boundary

The result assumes a linear, correctly configured signal. It does not diagnose loop power, wiring, burden, sensor faults, live-zero alarm bands, saturation, controller scaling, isolation, intrinsic safety, or whether extrapolation outside the entered range is acceptable.

Precision and reporting

Calculations retain working precision and round only for display. Very small and large nonzero values use scientific notation; displayed digits cannot create accuracy, traceability, or observational certainty absent from the entered data.

Category ownership

This collection owns neutral calibration relationships, instrument scaling, resolution, comparison, and first-order uncertainty worksheets. Statistical inference remains in Statistics; trade-specific inspection and field calibration remain with their professional collections.
