Coin-body mounting and loading crowns
Select the rated capacity within 10–1000 kg. The drawings are labelled 50–200 kg and 300 kg–10 t; the wider drawing range does not confirm availability above 1000 kg. Dimensional units and applicability to your chosen capacity require confirmation before fixture design.

Configuration and selection
The reference basis for the ±0.05% accuracy figure remains unconfirmed, while nonlinearity and hysteresis are each ±0.5% FS. These figures do not establish a confirmed overall accuracy rating. Specify the required error limit, capacity and operating conditions so the applicable performance can be confirmed before ordering.
- Rated capacity
- Versions within the 10–1000 kg range.
- Mounting
- Threaded installation.
- Signal
- Analogue voltage output with 1.5 mV/V nominal sensitivity.
