Features:
1)Standard 24-volt DC supply (working normally within 18-30 volt
range);
2)Output form:NPN/PNP;
3)Built-in direct control signal system;
4)It is suitable for winding tube, twisting thread, blending
wire and composite fiber deformation.
Basical functions:
Yarn breaking sensor can detect the
running (linear motion) of various types of spinning on the
spinning machine. When the
spinning stops or breaks, the capacitive yarn sensor can inform the
automatic control system of the spinning machine in
time.
According to the actual situation (determined by the model of
the spinning machine), the yarn sensor MCL1 can
directly drive the automatic wire cutter connected with
itself to cut off the weft at the corresponding position.
Control signal can also be sent to automatically stop the
corresponding spinning machine working position. In an
alarm state, MCL1 alerts field operators with flashing
signals from leds.
Capacitive yarn sensor is suitable for spinning made of all
materials that can carry electrostatic charge. For
elastane materials, the MCL1 series also provides a special
model (which can monitor low speed spinning
motion).
Opreating principle:
The capacitive yarn sensor probe can
monitor the voltage signal generated by the electrostatic
charge carried by the spinning
itself in the process of motion and judge the working condition of
the spinning according to its change. The
detection accuracy of capacitive yarn sensor is not affected by
dust. However, adverse working conditions such as oil
contamination or severe vibration will reduce the detection
accuracy of MCL1.
Safety instruction:
The wire sensor is mainly used for real-time detection of thin lines at high speeds.
No disconnection, it is widely used in high-speed winding heads in textile and chemical fiber equipment,
Bomb machine, etc. It uses the photoelectric system for detection, using non-contact inspection
The measuring method has the advantages of reliable performance and long service life. This series of products
Easy to install and convenient, it can be interchanged with imported products.
