Piece enters the alarm equipment alarm that the internal trigger of magnetic field detection area is connect with receiver.
The transmitter is low frequency transmitter.
The transmitter by transmitting antenna will emit signal emit, reception antenna receive transmitting antenna transmitting signal and
Make to form magnetic field detection area between transmitting antenna and reception antenna, received signal is transferred to receiver by reception antenna, if connecing
Receiving the signal strength change that device receives then makes alarm equipment alarm.
The centre frequency of the transmitter and receiver is 58kHz, and bandwidth is 57.8kHz to 58.2kHz；The amorphous
Body sheet metal intrinsic frequency 58kHz.
The utility model on cutter and stirring rod by installing amorphousmetal, amorphousmetal and transmitter and reception
The magnetic field formed between device the effect of meeting, amorphousmetal enter behind magnetic field to magnetic fields, and receiver is caused to receive
Intensity change so that alarm equipment alarm remind staff there is bulk metal to fall into scaling-off mouth, timely shutdown inspection avoids
Generation of the spiral arbor by bulk metal breaking phenomenon.The utility model uses specific amorphousmetal, can effectively avoid
Influence of the common metal to magnetic field improves accuracy of detection, avoids false alarm, improve work efficiency.Moreover, the utility model needle
It is strong to property, it is simple in structure, it is easy to operate, it is economical and practical.
