有谁知道传感器的灵敏度和偏移如何在很大的温差下发生变化?
应用说明说:
''TCSo - 灵敏度随温度变化:此参数定义灵敏度
随温度变化。例如,在 2.0g满量程范围内,灵敏度
变化在 0.01%/ C。因此,如果环境温度发生变化
40°C,从25°C到65°C,灵敏度变化范围为 0.01%* 40
= 0.4%,这意味着超过40 C的灵敏度变化在0.996 mg / LSB之内
1.004 mg / LSB,表明灵敏度相对于温度非常稳定
更改。因此,可以忽略灵敏度的温度补偿。''
这是否意味着如果我将温度提高40 C,他们不知道灵敏度会在哪个方向发生变化?这意味着''灵敏度变化。数据表中的温度'对我来说根本不会帮助我。

以下为原文
Does anyone knows how the sensors sensi
tivity and offset changes over a big temperature difference?
Application Note says:
''TCSo - Sensitivity change vs. temperature: This parameter defines how sensitivity
changes with temperature. For example, at a �2.0 g full-scale range, the sensitivity
changes within �0.01%/�C. Therefore, if the environmental temperature changes
40 �C, from 25 �C to 65 �C, then the sensitivity changes within the range of �0.01% * 40
= �0.4%, which means the sensitivity change over 40 �C is within 0.996 mg/LSB and
1.004 mg/LSB, which shows that the sensitivity is very stable versus temperature
change. Thus, temperature compensation for sensitivity can be ignored.''
Does this mean that they didn't know in which direction the Sensitivity will change if i increase the temperature by 40�C? That would mean the ''Sensitivity changevs. temperature'' in the datasheet would't help me at all.
