2 Terms and Definitions

Term Definition
Gamme de fonctionnement La plage maximale sur laquelle une sortie monotone peut être observée.
Gamme linéaire The maximum range over which the deviation of the output from a linear best fit is within a specified percentage value.
Linéarité The maximum deviation from a linear output as a percentage of the measurement range.
Répétabilité The maximum deviation in output when the sensor is tilted and then returned to its original position.
Résolution The minimum incremental position change that generates a monotonic output.
Symétrie The maximum deviation in output between two symmetrical positions on either side of null.
Courant maximal à zéro The maximum recommended current through the sensor at null at 23 °C which will not cause damage to the sensor.
Impédance nulle The impedance between the outer electrodes when the sensor is in the null position at 23 °C.
Température de fonctionnement The temperature range over which typical output behavior is observed.
Température de stockage The temperature range that will not physically or chemically alter the sensor while it is not in use.
24-Hour Stability The maximum variation in sensor output over a 24-hour period while the sensor remains stationary at null.
Coefficient de température nul The maximum output change at null per degree of temperature change above or below 23 °C.
Coefficient de température de l'échelle A coefficient to compensate for the change in gain caused by variations in temperature from 23 °C.
Compensation nulle The maximum deviation between the electrical null of the sensor and the mechanical null where the sensor is parallel to the surface of the Earth.
Cross-Axis Error The maximum deviation of the output on one axis while tilting along the perpendicular axis.
Constante de temps The amount of time required for the sensor output to reach at least 63.2% of its final value.
