C16A Self-Restoring Load Cell: Reliable Weighing up to 400 Tons
The C16 rocker pin load cell is designed to transmit forces in an optimal way, offering robust and precise performance with accurate weighing from 20 tons up to 400 tons. It also meets OIML R60 accuracy class C5.
This load cell can be used in harsh environments, such as truck scales for road or rail vehicles and silo level measurement. Versions with IP68/IP69K waterproof and dustproof ratings and IECEx-ATEX explosion protection are also available. Additional safety and reliability are provided through anti-rotation features, overvoltage protection, and durable cable options.
