2 Terms and Definitions

Term Definition
工作范围 可以观察到单调输出的最大范围。
线性范围 The maximum range over which the deviation of the output from a linear best fit is within a specified percentage value.
线性 The maximum deviation from a linear output as a percentage of the measurement range.
重复性 The maximum deviation in output when the sensor is tilted and then returned to its original position.
决议 The minimum incremental position change that generates a monotonic output.
对称性 The maximum deviation in output between two symmetrical positions on either side of null.
零点时的最大电流 The maximum recommended current through the sensor at null at 23 °C which will not cause damage to the sensor.
无效阻抗 The impedance between the outer electrodes when the sensor is in the null position at 23 °C.
操作温度 The temperature range over which typical output behavior is observed.
储存温度 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.
空心温度系数 The maximum output change at null per degree of temperature change above or below 23 °C.
比例温度系数 A coefficient to compensate for the change in gain caused by variations in temperature from 23 °C.
空心偏移 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.
时间常数 The amount of time required for the sensor output to reach at least 63.2% of its final value.
