sensorprecisie

Sensorprecisie refers to the overall quality of a sensor system’s measurements, focusing on how consistently and correctly it reports the value of the quantity it is intended to measure. In metrology, precision and accuracy are related but distinct: precision describes the reproducibility of measurements under unchanged conditions, while accuracy describes closeness to the true value. Sensorprecisie combines both aspects within the intended operating range and conditions.

Key performance metrics include resolution, repeatability, bias (systematic error), and drift. Resolution is the smallest change detectable by the sensor. Repeatability measures the spread of consecutive measurements under identical conditions. Bias is the deviation from the true value, while drift describes gradual change over time or with environmental factors. Other important factors are linearity, hysteresis, noise, and response time, all of which influence the practical usefulness of the sensor in real applications.

Sensorprecisie is affected by design and manufacturing tolerances, electronics, signal processing, and environmental conditions such as temperature, vibration, and electromagnetic interference. Calibration and traceability to reference standards are used to quantify and improve precision and accuracy. Regular calibration, shielding, proper excitation, and temperature compensation help maintain intended performance. Sensor fusion and filtering (for example with Kalman or complementary filters) can also improve effective precision in a system by combining multiple sensor readings.

Applications span industrial automation, robotics, automotive sensing, medical devices, and consumer electronics. When selecting a sensor, engineers consider the required precision and accuracy over expected operating ranges, and plan maintenance and calibration schedules to preserve sensorprecisie over the device’s lifetime.
