B550SD/B750SD SINGLE-ENDED BEAM LOAD CELL
Product description：
The B550SD series are typical and high precision, low profile single-ended shear beam available in a wide range of capacities. Full stainless steel construction and complete hermetic sealing ensures reliable accuracy and robustness in harsh industrial applications. The B550SD/B750SD are the ideal load cell for high precision weighing platforms with bolts by 2pcs through-holes firmly at end, meanwhile the force would be applied from the self-aligning level-pin settled into the blind hole at the other end vertically.
Main Features:
• Material: high-quality stainless steel
• Great long-term stability.
• Rated Capacities: 220kg~4.4t
• OIML R60, NTEP HB44, CE and RoHS certified
• IP Rating: IP68
• Suitable for platform scales, dosing system and process control in chemical, food, pharmaceutical and other industries.
• High precision by OIML R60 C10, high reliability.
• B750SD with 17-4PH material and PEEK strain gauge from HBK.
