Ring torsion load cell
Application
The load cell as transducer converts the mechanical input variable force proportionally into the electronic output variable voltage.
The specific model of the ring torsion load cell offers the user specific advantages:
The extremely small frame size simplifies the use in almost all weighing device applications
The robust construction allows problem-free transport, installation and operation, also under rough ambient conditions (disturbance forces, temperature)
Construction
Hermetically sealed encapsulation through laser welding and glass-metal implementation (IP68)
Corrosion protection through the use of stainless steel
All electrical components are located inside the load cell and thus are optimally protected
The high quality and robust connecting cable is guided radially into the load cell
Mechanically compatible with the RTK type series
Function
High reproducibility
High long-term stability and therefore consistently high accuracy permanently
Extremely small measured value influence as a result of lateral forces
High functional safety, even with frequently unavoidable impact loads and constraining forces, as well as with electrical interferences
Torque-free force input/output as a result of the direct, vertical power train
