Product description:
The B520 series are atypical and high precision, low-profile single-ended shear beam load cells, which are available in a wide range of capacities. Full alloy steel or stainless steel (optional) construction and complete hermetic sealing ensures reliable accuracy and robustness in harsh industrial applications. The B520 series are the ideal load cells for high precision weighing platforms with bolts by 2 pcs through-holes firmly at end, meanwhile the force would be applied from the self-aligning feet by the other end vertically.
Main Features:
• Material: Alloy steel，stainless steel optional
• Rated Capacities: 100kg~2t
• OIML R60, NTEP HB44, CE and RoHS certified
• IP Rating: IP67, IP68
• Suitable for floor scales, medical bed weighing and other electronic weighing devices.
• High precision by OIML R60 C5, high reliability.
