ADI CONTROLS Model ASP-681 is a strain gauge–based, low-profile bending beam load cell designed for precision large platform scale applications. Built from high-strength tool steel, it offers exceptional durability and can withstand heavy shock loads. Engineered for low eccentric load sensitivity, the ASP-681 supports platform sizes up to 1 x 1 meter while maintaining high accuracy and stable performance. Rugged and reliable, it is the ideal solution for large platform weighing systems, also known as Model 60810.

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.
