Description
High overload safety up to 100/400 bar.
Features
- High overload safety, optionally up to 40, 100 or 400 bar, due to the metallic pressure element limit stop, without liquid-filled measuring cell.
- Wide choice of special materials.
- Also available with liquid-filled case for high dynamic pressure loads or vibrations.
- Instruments with inductive contacts for use in hazardous areas with ATEX approval.
- Instruments with electronic contact for PLC applications.
