What is sensor drift?

The sensor drift is defined as “a small temporal variation of the sensor response exposed to the same analyte. under identical conditions” (Di Carlo and Falasconi, 2012). Drift causes a decrease in sensor sensitivity and. selectivity over time and affects measurement reproducibility.

How do you fix a drift sensor?

If a monitor is showing sensor drift try perform a calibration on the monitor. If the calibration process fails the sensor will need to be replaced. If calibration is successful but the sensor's readings still drift, verify that the sensor is properly installed and attempt to air out the sensor for an hour or two.

Why do sensors drift over time?

Pressure change frequency and amplitude, temperature extremes, material responses and environmental changes are all factors contributing to drift. The magnitude a sensor will drift varies with actual usage and the conditions it is exposed to.

What is temperature sensor drift?

Temperature drift is the behavior where for the same given physical quantity being measured, the sense element output is different at different temperatures. If this change in output due to temperature is not adequately compensated, it will appear as if the physical quantity being measured is changing.

What is drift in calibration?

What is Calibration Drift? Calibration drift can be defined as a slow change in the response of a gauge. It is a slow variation of a performance characteristic such as gain or offset.
