Usage: This detector is applied to plastic looms for stopping operation in case of broken weft and weft-out. It is composed of signal emitter, receiverand controller.
The system uses the emitter to send ultra high frequency signals after coding with signal coder and the secondary superheterodyne mixing receiver to accept the moving target signals.
系统中发射器采用编码器编码后发送超高频信号，接收器采用二次混频型超外差式接收移动目标信号。
