Applications Across Industries

Puretronics Load Cells are trusted across sectors for online and offline tension and weight monitoring:

• Film Industry
  AR-85 ensures accurate tension during winding and unwinding of BOPP, PET, or LDPE films. Perfect for extrusion lines and lamination units.

• Paper Manufacturing
  AR-ST handles high-capacity web tension in paper mills—ideal for corrugated, coated, or kraft papers. Installed at draw or rewind zones.

• Foil Production
  Foil sheets demand delicate handling. AR-85 or AR-125 provides reliable readings to avoid tearing or slack in aluminum or laminated foil processes. lamination units.

• Wire & Cable Plants
  Tension during cable payout and stranding is critical. AR-85 monitors it in real time, ensuring dimensional stability and electrical consistency.

• Textile & Non-Woven Lines
  Fabric tension must remain stable to avoid weave distortion. AR- 85 or AR-ST can be used on looms, coilers, or intermediate zones.

• Battery Separator Webs
  Ultra-thin separators used in lithium batteries require zero slack. AR-118 provides fine-tuned tension control to prevent micro-tears or folds.

• Conveyor Weighing
  Install AR-ST under conveyor belts for dynamic online weight monitoring in packaging, sorting, or batching applications.

• Offline Product Weighing
  Use AR-ST under platforms to build high-accuracy weighing stations for QC checks, manual packaging, or dispatch verification.

How Load Cells Work in Your Process

• 1. The load cell is mounted at a critical tension point—either at entry/exit rollers, intermediate rollers, or beneath weighing platforms.

• 2. As material passes over, the roller applies force proportional to the tension or weight.

• 3. The strain gauge within the load cell deforms slightly, producing a minute voltage change.

• 4. This analog signal is amplified and read by a controller, which displays real-time tension or weight and can be used to trigger feedback loops.

Best Practices for Installation

• Always pair one side with a roller bearing and the other with a load cell bearing.

• Lock the roller bearing to ensure zero lateral drift—this gives you the most stable and repeatable readings.

• Use shielded cables to avoid interference in high-noise environments.

• For web processes, install the load cell at the lowest vibration point on the frame.

Use Case Highlights

• Film Tension Control
  Installed on a PET extrusion line, an AR-85 load cell paired with a load cell amplifier cut roll rejection by 30% within the first month.

• Wire Production Monitoring
  A cable factory using AR-125 units was able to detect minute variations in payout tension, reducing insulation inconsistencies.

• Textile Quality Boost
  With AR-ST cells on its weaving line, a fabric plant minimized warp stretching, improving batch consistency and cutting rework.
