产品特点
GJC4/100型煤矿用高低浓甲烷传感器(以下简称为仪器)是微电脑控制带红外线遥控调节的智能型隔爆兼本安型仪表。该仪器能测定、显?#23601;?#26031;瞬时浓度,超限报警,可输出与被测瓦斯含量成正比的频率信号。仪器采用单片微机技术,具有性能稳定,可靠性高等特点。不仅可与我公司生产的KHJ4型风电甲烷闭锁装置配套,还可与各种煤矿安全监测系统配套使用。主要技术特点如下:
a.     性能稳定。本仪器所采用的传感器元件是长寿命、高稳定载体催化元件,调校周期长。
b.     灵敏度高。高性能的传感器元件加上仪器内部软件的自动非线性补偿使得仪器对甲烷的检测具有较高的灵敏度。
c.     可靠性高。本仪器具有开机自检、自动稳零、精度校正等功能,且采用红外遥控调校,整机没有任何调整孔,仪器的零点、精度的调整,报警值、断电值的设定以?#23433;?#25968;显示均由红外遥控器控制。可以避免开盖调试,减小机械损伤,提高整机的密封性,延长了仪器使用寿命。
d.     测量范围宽:本仪器只须一对催化元件就可连续检测0-10%甲烷,没有高低浓转?#36824;?#31243;,不怕高浓瓦斯冲击。
e.     本仪器调试简单,遥控器体积小巧,携带方便。
f.     本仪器软件功能强,整机结构简单,电路板所用元件少,具有较高的性能价格比。
g.     该仪器采用单一甲烷探头,检测0-100%CH4,具有较好的高、低浓?#29123;?#28919;检测转换特性,高、低浓度精度高,线性好。
主要用途及使用范围:
    该仪器主要用于煤矿井下,与KHJ4型风电甲烷闭锁装置或与各种通过?#26031;?#23478;指定防爆检验单位联检的“矿井环境检测系统分站”配套使用,连续检测其环境中的甲烷(CH4 )的含量,除就地数字显示甲烷浓度,超限“声”、“光”报警外,还可将与所检测的甲烷浓度成正比的频率、电流或电压信号传输给与制配接的风电甲烷闭锁装置或系统分站。
适用于煤矿井下采、掘工作面,回风巷道,机电峒?#19994;?#26377;瓦斯爆炸气体环境中对瓦斯浓度进行连续测定,断电控制,风电甲烷电闭锁等。
