OEM Weighing Solutions for Dynamic Weighing and Food Filling Machines

Rotary Filling Machines

Challenge: Rotary filling machines operate at high speeds with bottles or containers moving in circular paths. Centrifugal forces, rotary dynamics, and continuous vibration make accurate weighing extremely difficult. Side loads and impact forces can damage standard load cells, causing frequent failures and production downtime.

VPG Solution: Our Models 1410 and 1430 are specifically engineered for rotary filling applications. The 1430 features stainless steel construction with complete insensitivity to rotary dynamic forces, maintaining single-point performance at speeds up to 13 RPM. The 1410 offers two mounting options and effective isolation from base vibrations, with settling times of just 300 milliseconds for maximum throughput.

Result: Consistent fill accuracy, reduced waste, extended equipment life, and maximum production speeds without compromise

Checkweighers & In-Motion Weighing

Challenge: Checkweighers must make accept/reject decisions on products moving at high speed, often processing hundreds of items per minute. Split-second accuracy is essential to prevent underweight products (regulatory issues) and minimize false rejects (waste and throughput loss).

VPG Solution: Our fluid-damped load cells (Models 9010 and 240) deliver ultra-fast settling times between 40-300 milliseconds with built-in overload protection. The Model HPS hermetically sealed single-point load cell provides the precision needed for low-capacity applications, while our HBB series handles larger products. Integration with our DHS digital interface provides filtered, calibrated output for instant decision-making.

Result: Higher throughput, reduced false rejects, regulatory compliance, and improved overall equipment effectiveness (OEE)

Multi-Head Combination Weighers

Challenge: Combination weighers use multiple independent weigh heads to achieve target weights by combining different product quantities. The system requires exceptional speed, accuracy, and reliability across all heads to maintain productivity and minimize product giveaway.

VPG Solution: Our lightweight vLite™ technology and high-precision single-point load cells (Models 1010, 1033, 1042, HPS) provide the perfect solution for multi-head systems. Each load cell delivers OIML C6 accuracy with fast response times and excellent repeatability. Stainless steel construction with IP66/IP68 protection withstands the rigors of continuous operation in food environments.

Result: Reduced product giveaway, consistent target weights, maximum machine uptime, and improved profitability per package

Batching & Dosing Systems

Challenge: Precision batching for food ingredients, chemicals, or pharmaceutical products requires accurate measurement at various flow rates, often with corrosive or sticky materials. Systems must deliver consistent batches while minimizing waste and maintaining stringent quality control.

VPG Solution: Our extensive range includes compression load cells (Model 355, 5-500 kg) and shear beam designs (SHB series) with hermetically sealed, fully welded stainless steel construction. These solutions offer OIML R60 certification with 4000d to 10,000 divisions accuracy, perfect for precision batching. Optional current calibration output (SC version) ensures accurate parallel connection of multiple load cells in tank weighing applications.

Result: Precise ingredient control, reduced waste, compliance with formulation requirements, and improved product consistency

Loss-in-Weight Feeders

Challenge: Continuous feeding systems that monitor material loss over time require load cells that can track small weight changes accurately while materials are being actively dispensed. Vibration from feeder motors and material flow creates measurement noise.

VPG Solution: Single-point and low-profile load cells with high relative stiffness provide the stability needed for loss-in-weight applications. Our DHS digital interface with advanced configurable filtering removes noise while maintaining fast update rates, enabling precise control of feed rates for optimal process control.

Result: Accurate material usage tracking, optimized feed rates, reduced material waste, and improved process efficiency

Liquid Filling Systems

Challenge: High-speed liquid filling requires precise volume control across multiple filling heads, with rapid settling after each fill cycle. Foaming, splashing, and varying liquid viscosities complicate accurate measurement, while wash-down requirements demand robust construction.

VPG Solution: Our range of fluid-damped and hermetically sealed load cells provides the perfect foundation for liquid filling systems. Models with 150% to 400% overload protection handle the shock loads of high-speed filling, while IP68-rated construction ensures longevity in wet environments. Custom engineering accommodates specific mounting configurations and capacity requirements.

Result: Consistent fill volumes, reduced product loss, minimized overfill costs, and compliance with net-content regulations

Tank & Hopper Weighing

Challenge: Large-scale ingredient tanks and hoppers require load cells that can handle high capacities while providing accurate measurement for inventory control and batching. Mounting configurations must accommodate thermal expansion, wind loads, and agitation forces.

VPG Solution: Our compression load cells (up to 500 kg) and custom mounting modules are designed specifically for tank weighing applications. Stainless steel construction meets food industry requirements, while our current calibration output option simplifies the parallel connection of multiple load cells, ensuring accurate total weight measurement even with uneven loading.

Result: Accurate inventory management, precise batching control, reduced material waste, and improved process visibility
