ABB AO2000 LS25 激光连续监测系统

ABB LS25 分析仪适用于烟气脱销反应器出口处氨逃逸或者气体中 氨气和氧气的在线监测。 ABB LS25 分析仪由发射单元和接收单元组成，具有 IP66 防护等 级。发射端配置了主电路板、显示模块和信号输出模块，可以实 现原位安装、测量、显示、输出，无需光纤连接。通过 RS232 通 讯线与个人电脑连接，能够对该仪器进行维护和标定。

ABB LS25分析仪的测量基于可调谐二极管激光吸收光谱（TDLAS） 技术

特点及优势

• 免光纤设计 分析仪将传感器与中心单元整合，不需使用光纤，既杜绝了光信号的损耗和影响，减少对测量的影响，又节省了昂贵的光纤费用。简化了系统结构，方便现场安装和维护。

• 现场测量 测量在一个人们难以到达的地方进行，传感器直接监测工艺生 产中的气体，不需要使用取样管路。

• 测量速度快 测量以实时方式进行，能够实现对动态过程进行一个提前控制 并允许快速、低成本的校正。

• 测量精确 激光的本质特性决定了单一的

The ABB LS25 analyzer is suitable for on-line monitoring of ammonia escape at the outlet of flue gas run-off reactors or ammonia and oxygen in gases. The ABB LS25 analyzer consists of a transmitting unit and a receiving unit with IP66 protection. The transmitting end is equipped with a main circuit board, display module and signal output module, which can be installed, measured, displayed and output in situ without optical fiber connection. The instrument can be maintained and calibrated by connecting to a personal computer via an RS232 communication line.

The measurements of the ABB LS25 analyzer are based on tunable diode Laser Absorption spectroscopy (TDLAS) technology

Features and advantages

• The fiber-free design analyzer integrates the sensor with the central unit, eliminating the need for optical fiber, eliminating the loss and impact of optical signals, reducing the impact on measurement, and saving expensive fiber costs. The system structure is simplified and convenient for on-site installation and maintenance.

The measurements are taken in a location that is difficult for people to reach, and the sensors directly monitor the gas in the process production without the need to use sampling lines.

Fast Measurement speed Measurements are carried out in real time, enabling an advanced control of dynamic processes and allowing for fast, low-cost calibration.

• Measurement accuracy The intrinsic characteristics of the laser determine a single
