Vibration Sensor Output Scaling Worksheet
Calculate a nominal voltage-output sensor signal or a charge-output sensor plus charge-converter signal. The worksheet keeps pC and mV separate, requires the calibration context and does not invent dynamic range, clipping limits or usable bandwidth.

Equations and dimensional boundary
These are general linear scaling relations, not calibration procedures or formulas issued by ISO 16063.
U is the exact mechanical unit written in the record. The calculation does not convert between g and m/s2, or between velocity/displacement/acceleration. It never treats pC as mV.
Published charge-path example: PCB documents 10 pC/g multiplied by a 10 mV/pC charge converter as 100 mV/g system sensitivity; at 14 g, the expected output is 1400 mV or 1.4 V. The charge before conversion is 140 pC.

| S3 | PCB, Introduction to Charge Mode Accelerometers | Official public guidance distinguishes pC/g sensor output from mV/pC conversion and gives 10 pC/g * 10 mV/pC * 14 g = 1400 mV. It states that charge-sensor range and conditioner settings are model-specific. | Public dimensional model and worked charge-chain example. |
| S4 | PCB, Introduction to ICP Accelerometers | Official public guidance describes constant-current powering, DC bias, AC output, model-specific frequency response/calibration and examples relating mV/g sensitivity to peak measurement range. | Voltage-output sensor context and evidence that range is a chain/model property. |

Corrections made in this audit
pC is no longer calculated as mV
The former pC/g option used the same S times A divided by 1000 voltage formula as mV/g. The replacement first reports charge in pC and requires a separate mV/pC converter sensitivity before calculating voltage.
Dynamic range and dBV inventions were removed
The former page assumed a 1 mV noise floor and computed dBV from peak voltage. Noise depends on the sensor/electronics and bandwidth, while dBV uses an RMS voltage reference. Neither number is inferred here.
Generic maximum output is no longer a sensor range
A user-entered voltage alone cannot establish sensor, conditioner and DAQ headroom. The replacement names the model-specific limits that must be checked outside the nominal sensitivity product.
Calibration and operating context are required
Sensor identity, certificate/datasheet, quantity/unit, amplitude convention, frequency, mounting, temperature, cable, conditioner and DAQ record are explicit.
Unsafe defaults and implicit persistence were removed
Generic presets, prefilled values, automatic calculation, local history and context-poor clipboard output were removed. Inputs start blank and changed results become stale.
Input and runtime integrity were rebuilt
Decimal point/comma are accepted separately; mixed separators, negative levels, zero/negative sensitivities, missing charge gain, non-finite and overflow results are rejected. Error states clear prior numbers.
