Detailed instructions
Photoelectric yarn sensor is a kind of high precision, non-contact
photoelectric weft sensor, which is suitable for winding drum,
twisting thread, yarn blending and fiber deformation. Photoelectric
yarn sensor is a kind of easy to use, simple installation of broken
wire sensor.
Basical functions:
The photoelectric weft sensor can detect the running (linear,
reciprocating and circular) of various kinds of spinning on the
spinning machine. When the spinning stops or breaks, the
photoelectric type can inform the automatic control system of the
spinning machine in time. According to the actual situation (by the
type of the spinning machine).
The weft sensor can directly drive the automatic yarn 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 the alarm state, the photoelectric type is used to warn the
field operator with the flashing signal of the led.
Opreating principle:
The photoelectric yarn sensor detection head can measure the
operation of the spinning in the infrared beam, and judge the
working condition of the spinning according to the variation of the
voltage caused by the displacement.
The measurement accuracy of photoelectric yarn sensor will be
reduced due to the interference of external light source and other
adverse working environment.
The photoelectric yarn sensor has high detection capability, and
can detect the yarn weft of 0.02mm.
