Outstanding Weighing Technology for Large Loads
19.10.2021
RTN ring torsion load cells are low in height, extremely precise, and now even more robust
Ring Torsion Load Cells: Precise Weighing up to 470 Tons
RTN ring torsion load cells are available for a wide range of maximum capacities (1 t—470 t). All versions are compact and, at the same time, extremely robust. These properties and their superior degree of protection (up to IP 68/IP 69K) make them ideal for a wide range of container weighing applications, use in large platform scales, and the construction of vehicle scales – even in unfavorable environmental conditions.
HBM’s RTN load cells are extremely precise and minimize the influence of lateral load application with their unique ring-shaped strain gauges. Their high input resistance and low power consumption enable the use of battery-powered evaluation units for taking measurements.
Numerous special versions such as IECEx-ATEX or temperature-resistant versions (up to 110 °C) are available, and different cable lengths and cable types can be configured. A new version with an M12 connector is also available as an option for variants with accuracy class 0.05.

RTN with Improved Performance:
The heavy-duty load cell of the RTN series, which has been tried and tested for decades, has been further improved by the latest revision and equipped with new options. For example, it is now also available with a connector system for variants with 0.05 accuracy class. In conjunction with the connection cables (KAB175), which are available as accessories, the load cells automatically achieve the IP68/69K degree of protection when screwed on. Furthermore, the robust cable in a 6-wire circuit is halogen-free.
What's new:
* Improved corrosion resistance
* Version with connector (M12, only for 0.05 accuracy class, not legal-for-trade)
* New pre-wired connection cable for plug version available as an accessory
* Adjusted cable lengths
