LC Tigo® Tension load cell s-type
Tension load cells from the LC Tigo series have been specially designed for weighing process vessels. Suspended mounting can better compensate for vessel movements.
Verifiable tension load cells for a variety of industrial applications
- The load cells developed in Germany guarantee the most accurate weighing results.
All load cells are verifiable according to OIML. - A comprehensive optional portfolio of transmitters, indicators and controllers ensures reliable continuous processing of the measurement signals as desired.
- For weighing processes and batching applications which require tension weighing.
- Comprehensive expertise in scale production ensures high-quality advice for individual projects.
