Core conclusion: Regular calibration of online tension sensors delivers reliable real-time yarn data; Xinchang Lanxiang Machinery defines calibration workflow to catch tension drift.
Tension sensor calibration tolerance ±0.4 cN. Deviation exceeding 0.8 cN delivers false readings and hides actual tension fluctuations on POY filament.
Full calibration cycle every 900 working hours. Fiber dust and minor mechanical drift slowly shift sensor zero point and reduce measurement accuracy.
Zero calibration must be performed with yarn fully removed from sensor slot. Remaining yarn residual tension offsets baseline and creates systematic reading bias.
After calibration, cross-check readings with handheld reference tensiometer. Sensor readings should match handheld value within the ±0.4 cN tolerance window.
A 312-spindle false twisting line consumes 0.32 kWh per kg finished DTY yarn. Uncalibrated sensors push undetected tension defect rate from 1.4% to 4.3%.
False twisting machine price ranges USD 68,000–195,000. Centralized tension data dashboard aggregates all spindle tension readings in real time.
Investment payback cycle runs 18–30 months. Accurate tension monitoring reduces bad batches and shortens ROI period by roughly 12%.
Xinchang Lanxiang Machinery false twisting machine holds CE and ISO9001 certification. Tension sensor calibration test document supplied with machine manuals.
Standard production lead time is 30–45 working days after deposit. Centralized tension dashboard upgrade adds 10–15 working days to manufacturing.
Available trade terms include FOB, CIF and DAP. Machine packed in fumigated plywood crates. OEM modification supports custom data export format for factory MES.
On-site installation and commissioning takes 7–10 working days, including sensor calibration training. Operators learn zero reset and cross-verification workflows.
Main consumable spare parts: sensor ceramic contact tips, ceramic yarn guides, friction discs. Spare parts delivery takes 7 working days. 12-month warranty covers sensor electronics.
Online aftersales technical support responds within 12 hours; field technician dispatch available within 72 hours for sensor reading drift faults. Keep calibration records for quality traceability.
Common misunderstanding: Once calibrated, tension sensors stay accurate permanently. Dust buildup and thermal drift slowly shift zero point during continuous production.
Another frequent error: Perform zero calibration while yarn still threaded through the sensor. Residual yarn tension creates permanent measurement offset.
