Shear Beam Load Cell | OSBST

Accurate, Robust and IP68-Rated for Tough Weighing Applications. Applied Measurements OSBST 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 high integrity IP68 body and stainless steel construction of the OSBST single-ended shear beam load cell means that it is ideal for use in process situations where regular washdowns are required to maintain hygiene standards. Two mounting assemblies are available to suit Applied Measurements OSBST, 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, the OSBST single-ended shear beam load cell is available with ATEX (EEx ia IIC T6) hazardous area approvals. Third party products like the SB14 can be easily substituted by our OSBST product and will deliver similar performance and longevity.
