Term Definition
Campo di funzionamento Il campo massimo su cui si può osservare un'uscita monotona.
Gamma lineare The maximum range over which the deviation of the output from a linear best fit is within a specified percentage value.
Linearità The maximum deviation from a linear output as a percentage of the measurement range.
Ripetibilità The maximum deviation in output when the sensor is tilted and then returned to its original position.
Risoluzione The minimum incremental position change that generates a monotonic output.
Simmetria The maximum deviation in output between two symmetrical positions on either side of null.
Corrente massima a Nullo The maximum recommended current through the sensor at null at 23 °C which will not cause damage to the sensor.
Impedenza nulla The impedance between the outer electrodes when the sensor is in the null position at 23 °C.
Temperatura di esercizio The temperature range over which typical output behavior is observed.
Temperatura di stoccaggio 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.
Coefficiente di temperatura nullo The maximum output change at null per degree of temperature change above or below 23 °C.
Coefficiente di temperatura della scala A coefficient to compensate for the change in gain caused by variations in temperature from 23 °C.
Offset Nullo 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.
Costante di tempo The amount of time required for the sensor output to reach at least 63.2% of its final value.
