Features & Applications

The WL-121 is a bending beam load cell constructed from stainless steel, covering a capacity range from 50kg to 1000kg with a maximum platform size of 800×1000mm. This bending beam load cell features compensated off-center load error, making it ideal for applications requiring high accuracy under uneven loading. It is widely used in food, beverage, pharmaceutical, and other special fields, as well as belt scales, platform scales, and electrical weighing devices. Custom cable lengths and other options are available.

This bending beam load cell provides a combined error of 0.017%F.S., non-linearity of 0.017%F.S., and repeatability of 0.01%F.S. Rated output is 2.0±0.002mV/V, zero balance is ≤1%mV/V, and insulation resistance is ≥5000MΩ/100VDC. With recommended excitation of 5~15 VDC, this sensor ensures stable and repeatable measurements across a wide range of industrial conditions.

The WL-121 offers IP67 protection as standard, with customizable higher ratings. It operates within an extended temperature range of -40°C to 65°C. Nominal displacement is capacity‑dependent: ≤250kg models have <0.4mm deflection, while 500~2000kg models have 1.4~1.5mm deflection. Standard cable is Φ6.3mm × 2500mm, with custom lengths available. Safe overload is 150%F.S. The stainless steel construction provides excellent resistance to corrosion, making it suitable for frequent washdown and harsh environments.

Typical application:

• Food production lines: dynamic checkweighing and filling with sanitary requirements

• Beverage bottling: fill level control for cans, glass bottles, and PET containers

• Pharmaceutical processing: high-precision dosing and tablet counting in wet areas

• Belt weighers: continuous material flow monitoring for bulk solids

• Platform and bench scales: general industrial weighing up to 800×1000mm platform

• Special hygiene fields: meat, dairy, or seafood processing requiring IP67 rating

Shipping & Packaging

To ensure safe arrival at your location, the load cell will be carefully packaged and shipped. The packing process is as follows:

1. The load cell will be placed in a sturdy cardboard box to protect it from external damage during shipping.
2. The box will be filled with foam padding to provide additional cushioning and prevent the load cell from moving during shipping.
3. The load cell will be sealed in a plastic bag to protect it from moisture and other environmental factors.
4. Additional layers of bubble wrap will be provided for additional protection.
5. The carton is securely taped to prevent tampering.
6. A shipping label with your address and product information is attached to the box.
7. The package is shipped using a reliable and trusted freight carrier.

Once the package is shipped, you will receive a tracking number to monitor the status of your delivery. Please ensure that someone is available at the delivery address to receive the package to avoid any delays or problems.
