Single Point load cell LC aluminium
Accurate measurement results for scale production
Ideal for integration in bench scales, counting scales and checkweighers: with the LC made from aluminium Single Point load cells, you can rely on the tried-and-tested quality of a leading manufacturer of industrial weighing technology. Suitable for load ranges of 5 kg to 750 kg and a platform size of up to 800 mm × 800 mm.
Verifiable load cells for a variety of industrial applications
- The load cells developed in Germany guarantee accurate weighing results.
All load cells are verifiable according to OIML and NTEP. - Three different models cover a wide range of load levels – from 5 kg up to 750 kg.
- A comprehensive optional portfolio of transmitters, indicators and controllers ensures reliable continu- ous processing of the measurement signals as desired.
- Comprehensive expertise in scale production ensures high-quality advice for individual projects.
