GJC4低浓度甲烷传感器产品介绍

GJC4低浓度甲烷传感器满足了我国煤矿监测井下甲烷浓度的需要。它可以连续自动地将井下甲烷浓度转换成标准电信号输送给配接设备,并具有jiu地显示沼气浓度值,超限声光报警等功能。传感器经国家防爆检验机关进行联机检验后, 可与国内各类型监测系统及断电仪、风电瓦斯闭锁装置配套,适宜在煤矿采掘工作面、机电硐室,回风巷道等地点固定使用。

GJC4低浓度甲烷传感器主要特点

1.采用单片微机和高集成数字化电路,使电路结构简单,性能可靠,便于维修与调试。

2.实现了红外遥控调校零点、标校点、报警点等功能,使调校方便简单。

3.增加了传感器断电控制功能,并可任意设定断电点,实现了一机多用。

4.采用新型开关电源,降低了整机功耗,增加了仪器传输距离。

5.增加了故障自检功能,便于使用与维护。

6.设计了新的高强度外壳结构,增强了仪器抗冲击能力。
