E²T Quasar M8100PM

E2T QUASAR Flare Stack Pilot Monitor

This unique Pilot Flame Detection System is designed for continuous duty monitoring of pilot flames on flare stacks under varied environmental and changing weather conditions. It reports the presence of a flame via a 4 mA or 20mA current output; low current signal when Flame is detected, and high level current (alarm) when No Flame is detected.

这一独特的引燃火焰检测系统专门用于持续监测废气燃烧烟道中的引燃火焰。这一系统的核心部分是QUASAR M8100PM-EXP多波长、非接触式红外测温仪,该测温仪可从防爆外壳上拆除下来进行维修或更换,且不会影响整个系统的所有排线布线。QUASAR的透镜光学系统以及可供选择的不同光斑尺寸使其可以安装在距离所监测废气燃烧烟道最远为1300英尺的位置,可监测火焰运动、变化的发光体,适用于大多数的应用环境。精湛的透镜系统以及M-3旋转式支架使监测仪能够精确地瞄准目标物体。根据特定的位置或应用,还可自定义报警接点闭合、延时调节以及4-20 mA输出,可消除由于火焰间歇造成的错误报警。单个内置的烤炉加热探测仪确保了系统的长期稳定无漂移的操作。这一系统还配备了内部水基、旋转式支架以及空气吹扫管。

所有绝对零度以上的物体都会发射红外能量。所发射出的能量与物体温度成正比。QUASAR M8100PM-EXP通过一个可聚焦镜头系统收集能量,并将物体的能量聚集在一起,传输到灵敏的红外探测仪上。专用的放大电路将探测仪接收到的信号转化 成直流电,从而激活用于信号/无信号指示的继电器和mA输出。

QUASAR采用同步脉冲放大校正电路,在初始设定状态下会自动进行 校正,缩小由于天气条件造成的辐射放大。在测量物体时发生信号全部损失的情况下,一个可调节的延时电路会进行倒数计时,并激活“信号损失警报”。这一延时 功能可使火焰在强风或卡车完全堵塞以及诸如此类的情况下仍能恢复或被观测到。

警报输出端口是一个常开式的或常闭式的继电器,以及一个4-20 mA的电路,其中4 mA或以下有信号显示,而20 mA则无信号显示。

QUASAR M8100PM-EXP的所有电气和光学部件都安装在一个经由CSA和CENELEC认证的外壳内,其危险场所分类为第一类、第一部分、第C、D组;第一类、第二部分、第A-D组;以及EExd IIB T4。
