factory-direct weighing module, built to the application-specific capacity and accuracy your project requires.
The WST804 is a weighing module. All figures on this page come from the factory parameter sheet — what you read here is what ships.
Contact our engineers for the complete datasheet and design-in support.
WST804 hopper scale or small tank weighing system use bellows type load cell weighing module, A weighing module is essentially an industrial weighing element that integrates a load cell, connectors, mounting plate, and other components into a single unit. It allows for the easy conversion of equipment such as hoppers and reaction vessels into precise weighing systems. Its development not only preserves the high accuracy and stability of the load cell but also eliminates weighing errors caused by improper installation.
The weighing module has an automatic centering function, anti-eccentric load, and is easy to install. Widely used in belt scale, hopper scale, warehouse-scale, charging bucket, material mechanics testing machine, labor safety testing equipment, etc.

Direct manufacturing with 10+ years of OEM/ODM experience — custom capacities, connectors, cable lengths and branding.
Send your capacity, application and annual quantity — pricing, datasheet and sample options within 12 hours on business days.
Every unit is factory calibrated and inspected before dispatch; parameters on this page reflect shipped goods.
Self-aligned, lift-off protected modules integrate the WST804 into a self-contained mounting kit — drop onto legs of any tank, hopper or reactor and start weighing.
Drop-in kit
Pre-engineered silicone-pad or rocker-pin kits pair three or four WST804 units with a junction box — for a complete silo weighing installation.
3- or 4-point
Pharmaceutical, food and chemical reactors mount on weigh modules built around the WST804 — giving direct net-weight readout for batch control and inventory.
