WebSimultaneous detection of two analytes, carbon dioxide (CO2) and water vapor (H2O), has been realized using tunable diode laser absorption spectroscopy (TDLAS) with a single distributed feedback diode laser at 2.7 μm. The dynamic range of the spectrometer is extended from the low parts per million t … Weboptics. For the TDLAS setup, 1. Align the aspheric lens to achieve a well – collimated and symmetric beam. 2. Align the nearest mirror to direct the beam across the flame. 3. Adjust the mirror on the opposite side of the flame to direct the beam back across the flame. 4. Adjust the far mirror to direct the beam onto the detector. 5.

Tunable diode laser absorption spectroscopy (TDLAS, sometimes referred to as TDLS, TLS or TLAS ) is a technique for measuring the concentration of certain species such as methane, water vapor and many more, in a gaseous mixture using tunable diode lasers and laser absorption spectrometry. The advantage of TDLAS over other techniques for concentration measurement is its ability to achieve very low detection limits (of the order of ppb). Apart from concentration, it is … Web简述电动转向系统扭矩转角传感器. 一般来说，电动助力转向系统的基本策略如下图，可见其所有基本控制模块，其输入信号要么需要方向盘力矩信号，要么需要方向盘转角信号（方向盘转速通过转角信号计算得到），这两个信号一般来说是通过一个扭矩转角 ... countertop slabs toronto
