例如，假设有一种环境传感器能够感觉环境温度。
For example, say there is an environmental sensor that senses the current temperature.
为此，需要使用非接触式传感器，用于超清环境以及极端环境温度下的测量。
Non-contacting and wearfree magnetic bearings are used in ultra-clean atmospheres and in extreme ambient conditions.
在光学电流传感器系统中，光源的驱动电流与环境温度改变，都会造成光源峰值波长移动。
In an optical current sensing system, when the fluctuations of the driving current or the ambient temperature of the optical source used happens, the peak wavelength of the source will change.
