Series HC/RC because of the bore hole are typically applied for automatic control of axial thrusts on punching machines, on machine tools, presses, power hammers, actuators and also to control the tension of steel cables in the civil engineering field.

Load cells series HC/RC have a large diameter central bore hole. The force must be equally shared on the top circular area around the central hole, while the reaction force is on another circular area too; It is mandatory to equally apply the force (usually by means of ball-joints) in order to recover mechanical misalignments (increasing accuracy and avoiding metal yeldings).

The transducers are well shielded against dirt by means of siliconic sealants and rubbers allowing an IP65 rating.

Load cells have a built in calibration circuitry. A calibration certificate is provided together with each unit.

Series HC/RC load cells can be connected to indicators and conditioners supplied by S2Tech:

  • Mod. AN401Plus: signal conditioner and indicator with microprocessor
  • Multichannel data acquisition system mod. DSLab: It allows to acquire signal with high resolution and sample rate and to display data on PC

 

Note: All the listed units, connected to the washers HC/RC, set up complete measuring systems

*The load must be applied on the weighing axis, uniformly distributed on the weighing and base surfaces. Thrust spherical plane bearings are advisable. For dynamic loads, with shocks and vibrations, difficult to estimate, the max load allowed has to be reduced to avoid yielding and ruptures.
