Sensor Sensitivity
Compute a sensor's sensitivity, S = Δoutput/Δinput, the ratio of the output-signal change to the measured-quantity change that caused it. It is the slope of the calibration curve: a more sensitive sensor produces a larger signal change for the same input change, making reading easier. Expressed, for example, in mV/°C or mA/bar. Enter the output change and the input change.

Sensibilidade de sensor
A sensibilidade de um sensor é a 'inclinação' da sua curva de resposta: S = Δsaída/Δentrada — quanto o sinal de saída varia para cada unidade de variação da grandeza medida. Um termopar com 40 µV/°C, um sensor de pressão com 2 mA/bar: esses números são a sensibilidade. Um sensor mais sensível produz sinais maiores e mais fáceis de ler em meio ao ruído, mas pode saturar antes em faixas amplas. Não confundir com resolução (o menor incremento detectável) nem com exatidão (quão perto do valor verdadeiro): um sensor pode ser muito sensível e, ainda assim, impreciso. Informe a variação da saída e a variação da entrada.

ADC Resolution
Compute the resolution of an analog-to-digital converter (ADC), R = FSR/2ⁿ, dividing the full-scale range (FSR, in volts) by the number of levels (2 to the power of the number of bits). It is the smallest voltage step the converter distinguishes — the more bits, the finer the resolution: a 12-bit ADC divides the range into 4096 levels. Fundamental in data-acquisition and digital-instrumentation design. Enter the full-scale range and the number of bits.
Expanded Uncertainty
Compute the expanded uncertainty of a measurement, U = k · uc, multiplying the combined uncertainty (uc) by the coverage factor k. While the combined uncertainty corresponds to ~68% confidence (1σ), the expanded one defines a higher-confidence interval — with k = 2, about 95%, the standard in most calibration certificates. It is the final value reported as '± U' in the result. Enter the coverage factor k and the combined uncertainty.
