Product description：
The B550SD series is a digital single-ended shear beam load cell with a precision of C10. They can be daisy-connected and does not require a junction box. The built-in microprocessor actively monitors environmental changes, continuously compensates for various performances in real time, and indicate the parameter status of each load cells, ensuring the weighing results more accurate and stable. The hermetically sealing process ensures high sealing performance and can work normally in harsh industrial environments.
Main Features:
• Material: high-quality stainless steel
• Rated Capacities: 550kg~4.4t
• CPA C8, CE and RoHS certified
• IP Rating: IP68, IP69K
• Suitable for platform scales, dosing system and process control in chemical,food,pharmaceutical and other industries.
• Built-in real-time self-compensation microprocessor, high accuracy up to OIML R60 C10 and high reliability
• B750S with 17-4PH material and PEEK strain gauge from HBK.
