Single-Ended Shear Beam Load Cell | OSBKT

At a Glance

Description

Applied Measurements OSBKT single-ended shear beam load cell is suitable for medium capacity weighing applications such as hoppers and vessels where a highly accurate measurement system is required.  They are also suitable for conveyor weighing applications.

The OSBKT single-ended shear beam load cell’s high integrity IP67 body and alloy steel construction make it ideal for general purpose industrial weighing applications where low-cost is a primary consideration.

Two mounting assemblies are available to suit the OSBKT single ended shear beam load cell; the Vessel Mount for static applications and the Shock / Anti-Vibration Mount for mixer, feed hopper and conveyor applications where vibration or transient loads may occur.  For mount dimensions, please download the datasheet.

For hazardous environments, our OSBKT single-ended shear beam load is available with ATEX (EEx ia IIC T6) hazardous area approvals.

Other discontinued third party products like the AW420/01000 can be easily substituted by our OSBKT-1000kg-003-000 product and will deliver similar performance and longevity.
