Electronic Stress Transducer
Specialized hardware utilizes the properties of certain crystals to generate a voltage in response to mechanical pressure from yarn. The piezoelectric tension sensor captures high-frequency fluctuations in the warp or weft threads that traditional mechanical devices might miss. This device is particularly effective in high-speed weaving environments where rapid detection of tension spikes is necessary.
Signal Processing Mechanism
As the yarn passes over the ceramic element of the sensor, the varying pressure creates a proportional electrical charge. A piezoelectric tension sensor transmits this data to the loom computer, which then analyzes the waveform for anomalies. This system detects subtle changes caused by yarn knots or uneven sizing on the flax fibres.
The lack of moving parts in these sensors makes them highly durable and resistant to the dust and lint found in linen mills. It provides the high-speed response required for modern air-jet or rapier systems.
Weaving Precision Application
Accurate tension data is essential for preventing defects such as weft loops or tight picks in the linen cloth. Integrating a piezoelectric tension sensor into the weft feeder allows for precise control of the yarn release during the rapier stroke. This level of monitoring ensures that the yarn is neither too loose nor too tight as it enters the shed.
Reliable tension sensing is a fundamental requirement for the production of premium linen fabrics.
