FRONT ELEVATION (ZERO PARASITIC FORCE)
Height
L
Max Fold Dia (Dmax)
KINEMATIC DETAIL: WEIGHING ACCURACY
Zero Parasitic Tare Force Principle:
1. Standard straight hoses act like springs (F = k*x).
This causes mechanical piping resistance errors.
2. The Outward Convoluted Fold creates a hinge effect.
Vertical stiffness (k) is eliminated (≈ 0).
PLAN VIEW
• Material Base: Ultra-Flexible Ether-TPU or Silicone
• Thickness: 0.5 mm to 1.0 mm (Ultra-thin wall for zero stiffness)
• Key Feature: Pre-formed Outward Expansion Hinge Fold
• Accuracy: 100% Gravimetric Accuracy on Load Cells
• Vibration Control: Absorbs and decouples high-frequency vibration.
• Compliance: FDA 21 CFR 177.1680
