RXHFZ-TX-CAN2.0 can directly replace ROJ TE400 Cmatic weft detector
The RXHFZ-TX-CAN2.0 is a piezo-electric weft yarn detectors with a current output
signal proportional to the number of wefts running at the same time. It can perform
as a single filling insertion control or a double filling insertion control (ANTI-2 and
ANTI-3 functions). The configuration may have 8 eyelets.
The RXHFZ-TX-CAN2.0 has been developed to meet the requirements of
those weaving companies which often change articles or weave different yarn types
at the same time.
RXHFZ-TX-CAN2.0 advantages
Advantages for the weaver
The RXHFZ-TX-CAN2.0 has been developed to meet the requirements of those
weaving companies which often change articles or weave different yarn types at the
same time.
No manual adjustments are needed for sensitivity settings.
Each eyelet is able to find independently the best regulation by adapting the
control to the characteristics of each single weft.
This helps the optimization of the weft arrival setting.
The use of the CAN BUS system allows the sensor control on real time and the
data acquisition for sensitivity monitoring.
TheRXHFZ-TX-CAN2.0 can manage, without problems, yarns with very different
counts and roughness characteristics.
The RXHFZ-TX-CAN2.0 weft feeler can be used with the following looms.
LEONARDO – VAMATEX - ALPHA – SOMET
N.B. In some case a software update from the loom manufacturer may be required.
Automatic sensitivity adjustment (Patent pending).
A signal provided by the loom control-board, synchronised with the end of weft control,
allows separate eyelet automatic sensitivity adjustment and optimised for specific
\yarns working parameters. A couple of picks for each weft are necessary to obtain
the best sensitivity adjustment.
All the flexibility of CAN-BUS
RXHFZ-TX-CAN2.0 will interface any loom with full-CAN standard bus, for set-up
data transfer or runtime information exchange.
Output signal
Current Output Signal: three different current levels depending on the number of yarns
simultaneously moving.
