Sensor sentivity in pressure measurement systems indicates how much the sensor 's output changes in response to a change in pressure. Calculating this sentivity helps in selecting applicate sensors and ensuring exaction measurements.

Understanding Sensor Sensitivity

Sensitivity is typically expressed as the ratio of output change to te pressure change, of ten in units such as mV / Pa or mV / kPa. It reflects thee sensor 's ability to detect small variations in pressure.

Krok to Calculate Sensor Sensitivity

Follow these steps to determinate thee sentivity of a pressure sensor:

  • Aplikujte na know pressure to te sensor.
  • Record thee sensor 's output voltage or signal.
  • Repeat thee measurement at different pressure levels.
  • Vypočítejte si to.

Example Calculation

If a sensor produces an output of 2.0 mV at 100 kPa and 4.0 mV at 200 kPa, thee sensitivity is calculated as:

Sensitivity = (4.0 mV - 2.0 mV) / (200 kPa - 100 kPa) = 2.0 mV / 100 kPa = 0.02 mV / kPa.
