Ring Torsion Load Cell RTN 1 t \u2026470 t<\/h4>\n<\/div>\n
Application<\/strong>
\nAs a measuring transducer, the load cell converts the mechanical input variable ‘force’ proportionally into the electrical output variable ‘voltage’.
\nThe consistent optimization of the ring torsion load cell offers the user specific advantages:
\n\u25aa The extremely small frame size simplifies the use in almost all weighing device applications
\n\u25aa The durable design allows easy transportation, installation and operation, even in very rough ambient conditions (disturbing forces, temperature)<\/div>\n
\u00a0<\/div>\n
Construction<\/strong>
\n\u25aa Hermetically sealed encapsulation through laser welding(IP68)
\n\u25aa High corrosion protection thanks to electrolytically polished stainless steel
\n\u25aa All electrical components are located inside the load cell and thus are optimally protected
\n\u25aa The high quality and robust connecting cable is guided radially into the load cell
\n\u25aa In combination with adapter kits, the RTN load cells are compatible with former designs.<\/div>\n
\u00a0<\/div>\n
Function<\/strong>
\n\u25aa High measuring sensitivity
\n\u25aa High reproducibility
\n\u25aa High long-term stability and therefore consistently high accuracy permanently
\n\u25aa Extremely small measured value influence as a result of lateral forces
\n\u25aa High functional safety, even with frequently unavoidable impact loads and constraining forces, as well as with electrical interferences
\n\u25aa Integrated overvoltage protection
\n\u25aa Torque-free force input\/output as a result of the direct, vertical power train
\n\u25aa Plug variants for fast and inexpensive replacement of damaged cables<\/div>\n

Allowed static transverse load Lq = 0.5 (Emax<\/sub> \u2013 0.8 Lz<\/sub>), however maximum Lqmax<\/sub> = 0.2 Lz<\/sub>; Emax<\/sub> = nominal load; Lz<\/sub> = Load in measuring direction. Allowed vibration stress acc. to DIN 50100: 70 % Emax<\/sub>. Here, the peak load value Emax<\/sub> may not be exceeded.
\nIn combination with elastomer bearings, SEM must be observed that the reset force of the elastomer bearings of the self-aligning bearings already represents a transverse force.<\/div>\n
