Description

The model F1270 high-capacity load cell with strain gauges is designed for measuring very high loads and has been specially designed for use in container and silo weighing technology.

The spherical cap with convex surface is used to transfer compressive forces and ensures axial, perpendicular and centred force introduction. The force is thus transmitted centrally and evenly into the instrument. This enables precise measurement of the actual compression forces in a wide variety of applications.

The measuring body is elastically deformed by a compression force introduced in the force direction. The resulting mechanical tensions are measured by the strain gauges, converted into an electrical output signal and output as an mV/V signal.
