产品基本内容
GFK50风门传感器最好的质量
Product synopsis:
This product can be with all kinds of coal mine monitoring system supporting, online detection coal mine underground ventilation roadway set in the throttle "on" and "off" status.
工作原理:
干簧管在磁场中,当磁场达到一定强度时,其中常闭触片与原来吸合的触片脱开,与另一常开触片吸合,当干簧管脱离磁场时,又恢复原来的状态。利用这个原理,将带有干簧管的传感器组和产生磁场的磁钢组分别安装在风门的门框和门的边缘(两者相对),利用风门位置的变化,产生开关信号,送至监控系统。
主要技术指标:
测量范围 (0~30)mm干簧继电器吸合 输出信号 开关量
接点容量 DC36V/100mA 传输距离 ≥2km
防爆型式 Exib I 外形尺寸 传感器组件110×60×35mm
磁钢组件 80×40×25mm重量0.4kg
Working principle:
Dry reed pipe in a magnetic field, when the magnetic field to a certain strength, the normally closed contact with original suction line of contact release, and the other a normally open contact suction close, when dry reed pipe from magnetic field, and restore its original state. Using this principle, will with dry reed pipe sensor group and produce a magnetic field of magnetic steel groups were installed in the air door frame and the edge of the door (both relative), the use of throttle position change, produce switch signal, sent to the monitoring system.
