Signal Scaler

Signal Scaler is a fast, straightforward calculator for instrumentation technicians, controls professionals, electricians, and engineers working with 4–20 mA signals. Quickly convert between: • 4–20 mA signal values • Percentage of calibrated range • User-defined engineering units • Differential-pressure percentage • Square-root flow percentage Enter the transmitter’s lower and upper range values, then calculate the corresponding current, percentage, or engineering-unit value. Features include: • Linear 4–20 mA scaling • Differential-pressure-to-flow square-root calculations • Adjustable LRV and URV • User-defined engineering units • Quick selection of common 8, 12, and 16 mA values • Automatic limits for valid signal and percentage ranges • Simple interface designed for field use • No account required • Works offline Signal Scaler is intended as a convenient calculation aid. Always verify critical values using approved procedures and calibrated test equipment.
