What applications is RL1521A best for?

The RL1521A works great for bench scales, retail counters, small hoppers, packaging stations, and light-duty platform scales—anywhere low-capacity weighing with precision is needed.

Can the RL1521A be used in food processing or humid environments?

Given its aluminum construction and lack of heavy environmental sealing, it is best suited for clean, dry indoor environments. For wash-down or wet areas, a stainless or hermetically sealed load cell is recommended instead.

What cable length comes with this load cell?

The RL1521A is supplied with a 10-foot cable, simplifying installation and retrofits for most small to medium scale systems.

Is this load cell suitable for legal-for-trade scales?

Yes. The RL1521A is NTEP approved and suitable for use in many legal-for-trade applications when installed in an appropriate scale system.

Can I use the RL1521A to replace older cells?

Yes. Many bench scales and small platform scales use single-point cells of similar capacity. If the original cell matches capacity and mounting footprint, the RL1521A can often be used as a drop-in replacement. Contact us with your scale model for help if you are unsure.

The Rice Lake RL1521A aluminum single-point load cell offers lightweight, cost-effective and precise weighing capacity for compact bench scales, small platform scales, retail hoppers, and OEM applications. Designed for light-duty industrial use, this model is ideal when you need a reliable load cell for capacities from 3 kg up to 35 kg, with a convenient 10 ft cable for easy installation or retrofits.

Whether you’re upgrading a lab balance, building a small hopper scale, or replacing a worn single-point cell, the RL1521A delivers stable performance, repeatable readings, and a straightforward setup — making it an excellent choice for lower-capacity weighing systems where accuracy and simplicity matter most.
