A Sensor senitivity in pressure measurement systems indicates much the sensor 's output changs in response te to a change in pressure. Calculating tis senitivity helps in selecting acacidate sensors and ensuring precinate measurements.

Understanding Sensor Sensitivity

Sensitivity i typically expressed as the ratio of output change to the pressure change, oftein in it uns such units mV / Pa or mV / kPa. It reflects the sensor 's ability to detect small variations in pressure e.

Steps to Calculate Sensor Sensitivity

A pressure sensor:

  • Apply a know pressure to the sensor.
  • Record the sensor 's output voltage or signol.
  • A többi mérésvizsgálat különböző nyomásfokozatokat mutat.
  • Számítsa ki a változót, és adja ki a dividedet.

Example Calculation

A szenzor előállításai a 2,0 mV at 100 kPa and 4.0 mV at 200 kPa, the sensitivity i computatede a:

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