2 Terms and Definitions

Term Definition
Rango de operación El rango máximo en el que se puede observar una salida monótona.
Rango lineal The maximum range over which the deviation of the output from a linear best fit is within a specified percentage value.
Linealidad The maximum deviation from a linear output as a percentage of the measurement range.
Repetibilidad The maximum deviation in output when the sensor is tilted and then returned to its original position.
Resolución The minimum incremental position change that generates a monotonic output.
Simetría The maximum deviation in output between two symmetrical positions on either side of null.
Corriente máxima en nulo The maximum recommended current through the sensor at null at 23 °C which will not cause damage to the sensor.
Impedancia nula The impedance between the outer electrodes when the sensor is in the null position at 23 °C.
Temperatura de funcionamiento The temperature range over which typical output behavior is observed.
Temperatura de almacenamiento 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.
Coeficiente de temperatura nulo The maximum output change at null per degree of temperature change above or below 23 °C.
Coeficiente de temperatura de la escala A coefficient to compensate for the change in gain caused by variations in temperature from 23 °C.
Compensación nula 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 tiempo The amount of time required for the sensor output to reach at least 63.2% of its final value.
