产品特点
      GTH1000煤矿用一氧化碳传感器(以下简称为传感器)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。该传感器能测定、显示煤矿井下大气中一氧化碳瞬时浓度,超限报警,可输出与被测一氧化碳含量成正比的频率信号。传感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型风电一氧化碳闭锁分站配套,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。本传感器所采用的传感器元件是英国尼宗尼克公司生产的长寿命CO传感元件、具有稳定性好,调校周期长等特点。
b.     灵敏度高。高性能的传感器元件加上传感器内部软件的自动非线性补偿使得传感器对一氧化碳的检测具有较高的灵敏度。
c.     可靠性高。本传感器具有开机自检、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,传感器的零点、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,延长了传感器使用寿命。
d.测量范围宽:本传感器可检测0-1000×10-6CO,不怕高浓一氧化碳冲击。
e.本传感器调试简单,遥控器体积小巧,携带方便。
f.本传感器软件功能强,整机结构简单,电路板所用元件少,具有较高的性能价格比。工作条件
温度:0-40
相对湿度:≤98%(25℃);
大气压力:86-116kPa;
