氮气气体检测仪安装及使用注意

氮气气体检测仪安装及使用注意
氮气气体检测仪广泛应用于冶金、石化、市政、化工等行业,气体探测器的核心部分是电化学传感器,氮气检测报警仪器适用于检测空气中氮气的浓度。
如果空气中氮气(N2)浓度超过检测仪设定的报警值,仪器就会发出声光报警。
一、氮气气体检测仪安装位置
1、氮气(N2)的密度小于空气,氮气检漏仪应当安装在泄漏点的上方0.5米-2米处,且传感器部位向下。
2、仪器请勿安装在以下位置:
①直接受到蒸汽、油烟影响的地方。
②给气口,换气扇,房门等风量流动较大的地方。
③水气,水滴多的地方(相对湿度:≧90%)。
④温度在-30℃以下或50℃以上的地方。
⑤有强电磁的地方。
二、氮气检测使用注意事项:
1.注意氮气探测器等各种有毒有害气体探测器的浓度测量范围,其检测范围是固定的。
只有在测量范围内完成测量,仪器才能准确测量。
如果传感器长时间超出测量范围,可能会造成永久性损坏。
2.注意不同传感器之间的检测干扰:一般来说,每个传感器对应一个特定的气体检测,但任何气体检测仪器都不能是绝对的。
因此,在选择气体传感器时,有必要尽可能了解其他气体对传感器检测的干扰,以确保其准确检测特定气体。
3.注意定期校准和测试:有毒有害气体检测仪和其他分析仪器一样,采用相对比较方法进行测量:仪器采用零气体和标准气体浓度进行校准,标准曲线存储在仪器中,将测量气体浓度产生的电信号与标准气体浓度的电信号进行比较,计算出准确的气体浓度。
因此,需要定期检定校准仪器。

Pressing the ZERO (C) button for 6 seconds and releasing will restart the zeroing process. NOTE: If a sensor is completely inoperable or improperly zeroed at start up, the display will show “bAd”.4. All instruments read with a resolution of 10ppm up to 990ppm. The scale automatically switch to LEL when 990ppm is exceeded with a resolution of 0.1% LEL.Optionally all readings may be displayed in LEL only. Readings beyond 100% LEL are indicated by “OL” (overload).5. It may be necessary to manually zero the instrument based on company practices and environmental conditions.⚠CAUTION: Zeroing should be done in a gas free environment only.6. When testing high areas or overhead lines the use of the optional extension adapter will allow a broom handle or painters stick to extend the instrument to the area where sensing must be accomplished. This slides onto the battery sleeve and is held in place by the locking nut assembly.7. When a gas is sensed the display will update. If an alarm condition exists, based on a preset alarm point, the red LED will flash and the alarm will sound.8. During an alarm condition (factory default at 10% LEL methane) the display will flash and an audible alarm will sound indicating a potentially unsafe environment. To disable the audible alarm press and release the MUTE button (A). To enable the alarm press and release it again.NOTE: These instruments have cross sensitivities to a variety of gases.9. To assist in locating the source of small combustible gas leaks or surveying areas outdoors or indoors, press and release the TICK/CAL button (B). This will start an audible tick preset at 2-3 ticks per second. Move the sensor toward the area suspected of leakage. As the sensor moves closer to a leak source the tick will increase. When the tick becomes a steady tone press the TICK/CAL button (B) again while keeping the sensor head in the same position. This will slow down the tick and allow the operator to find a higher concentration using the same procedure.If there is no tick, press the TICK/CAL button (B) again to reset to the steady ticking sound. For best results always use the leak detector prior to using any liquid leak detection fluids as these sensors will detect their presence.10. Following Country, Province, State, Municipal and/or Company procedures move to the areas where gas readings are suspected or must be tested. During sampling the respective readings may change. Audible and visual alarms will activate when the preset limits are reached.11.

氮氢检漏仪原理
氮氢检漏仪原理氮氢检漏仪是一种用于检测氮氢气体泄漏的仪器,其原理主要基于氮氢气体的特性和检测技术。
氮氢气体是一种常见的工业气体,在许多行业中被广泛使用,但是如果泄漏发生,可能会对环境和人员造成严重的危害。
因此,使用氮氢检漏仪进行定期检测是非常重要的。
氮氢检漏仪的原理主要包括两个方面,氮氢气体的特性和检测技术。
首先,我们来看一下氮氢气体的特性。
氮氢气体是一种无色、无味、无毒的气体,具有较高的热导率和低的比热容,同时也具有一定的可燃性。
这些特性使得氮氢气体在空气中具有一定的扩散性,一旦泄漏,会迅速扩散到周围环境中。
基于氮氢气体的这些特性,氮氢检漏仪采用了一种特殊的检测技术来进行泄漏检测。
检测技术主要包括两个方面,传感器和信号处理。
传感器是氮氢检漏仪的核心部件,它能够对氮氢气体进行高灵敏度的检测,并将检测到的气体浓度转化为电信号输出。
信号处理部分则对传感器输出的信号进行放大、滤波和处理,最终将结果显示在仪器的显示屏上。
在进行氮氢泄漏检测时,氮氢检漏仪首先需要进行预热,使传感器处于稳定工作状态。
然后,将检测头置于可能存在泄漏的区域,待仪器显示出稳定的氮氢浓度数值后,可以判断是否存在泄漏。
如果检测到氮氢气体浓度超过了设定的安全阈值,仪器将会发出警报,提醒操作人员及时采取措施。
总的来说,氮氢检漏仪的原理是基于氮氢气体的特性和检测技术,通过传感器对氮氢气体进行高灵敏度的检测,并通过信号处理部分对检测结果进行处理和显示。
使用氮氢检漏仪可以及时准确地发现氮氢泄漏,保障生产和人员的安全。
以上就是关于氮氢检漏仪原理的介绍,希望能对大家有所帮助。
