Weighing Platform/Hopper: Capacity 50 kg to 10,000 kg

Component Specifications

Definition

A structural component designed to hold and weigh bulk materials, powders, or liquids with high accuracy. It integrates load cells or force sensors to measure weight, often featuring vibration isolation, dust sealing, and discharge mechanisms for controlled material handling in automated production lines.

Working Principle

Operates on the principle of force measurement using strain gauge load cells. When material is loaded, the platform's weight causes deformation in the load cells, changing electrical resistance. This signal is converted to a digital weight reading by a transmitter or controller, enabling precise batch control and inventory management.

Materials

Stainless steel (AISI 304/316) for food/pharma, carbon steel with epoxy coating for general industry, aluminum for lightweight applications. Seals: FDA-grade silicone or nitrile rubber.

Frequently Asked Questions

What is the difference between a weighing platform and a hopper?

A weighing platform is typically an open flat surface for general items, while a hopper is an enclosed container with discharge mechanisms (e.g., valves, screws) for powders or granules, often used in continuous processes.

How often should weighing platforms be calibrated?

Calibration should be performed annually or per ISO 9001 requirements, with more frequent checks (e.g., monthly) in high-precision applications like pharmaceutical batching.
