High Capacity-High Accuracy Tension and Compression Canister Load Cell-Series CNR960
These load cells are uniquely engineered to ensure a fast frequency response thanks to minimal deflection. They are constructed of nickel plated carbon steel that is electroless, and you can enjoy peace of mind that they are shock and vibration resistant.
As standard, each unit comes shipped with a 10 point calibration (5 points each in both compression and tension) record traceable to NIST.
The Series CNR960 tension / compression canister style load cells are designed specifically for high capacity and high accuracy test and measurement applications requiring long fatigue life combined with high resistance to the effects of extraneous bending and off-axis loading.
The uniquely engineered CNR960 Series load cells have a minimum deflection resulting in fast frequency response. Constructed of electroless nickel plated carbon steel, all CNR960 load cells are manufactured to be shock and vibration resistant. Each unit is shipped with an 10 point calibration (5 points in both tension and compression) record traceable to NIST as standard.
