ADI CONTROLS Model ASP-621 is a low-profile, single-point load cell designed for platform weighing applications. Constructed from high-strength tool steel, it is ideal for harsh industrial environments. The cell features an electroless nickel-plated finish for enhanced corrosion resistance and utilizes strain gauge technology with full temperature compensation from 0°C to 60°C, ensuring stable and precise performance. Higher capacity versions are available upon request. The ASP-621 delivers high accuracy and reliability, making it a durable, low-profile solution for platform weighing — also known as Model 60210.

A single point load cell (also known as a platform load cell or parallel beam load cell) is a type of force sensor designed to provide an accurate reading regardless of the position of the load on its weighing platform. It achieves this by having a minimal sensitivity to off-center loading.
The primary advantage is its independence from eccentric loading (off-center loading). Since its design inherently compensates for varying load positions, you only need one single point load cell to measure the weight accurately on a given platform, simplifying the mechanical design and calibration of the weighing system.
