B550S/B750S SINGLE-ENDED BEAM LOAD CELL
Product description：
The B550, B750 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 B550, B750 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: 550kg~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 C5, high reliability.
• B750S with 17-4PH material and PEEK strain gauge from HBK.
