Bending Beam Load Cell

Description

The OBBS bending beam load cell design is suitable for low capacity weighing applications such as batching hoppers where a highly accurate measurement system is required.  They are also suitable for use in conveyor weighing applications.

The bending beam load cell’s high integrity hermetically sealed IP68 bellows and stainless steel construction means that it is ideal for use in process situations where regular washdowns are required to maintain hygiene standards.

A vessel mount is available to suit the OBBS bending beam load cell for static applications and is ideal for load cells in hopper and tank weighing applications.
