Product description：
The P520SD is a typical digital high-precision canister compression load cell with double-cut faces against rotation. The P520SD is fully hermetically sealed with stamped integrated canister; which enable it to work in the harshest conditions. A rocker column design ensures optimum weighing accuracy when subjected to off-center and side forces when the scale deck is moving back and forth, meanwhile left and right.
Main Features:
• Material: Stainless steel
• Rated Capacities: 30t~50t
• Compensation mode: active compensation for non-linearity, creep, hysteresis, ZTC, STC, etc.
• Advanced quick Protocol CANopen by 125 kbit/sec
• OIML R60, NTEP HB44, CPA, CE and RoHS certified
• IP Rating: IP68, IP69K
• Suitable for truck scales, heavy duty hopper scales, force measurement equipment.
• High precision by OIML R60 C6, high reliability
