Mechanical pressure switch 620
The pressure switches of Type 620/625 with 13 pressure range gradations are suitable for liquids and gases. Pressure connections are available in ABS, PA 66, brass, or aluminum, and the membranes in NBR-based, FPM, EPDM, or silicone. Very precise due to finely tuned measuring ranges and high long-term stability. Robust design and therefore particularly suitable for general equipment construction, process engineering, and food automation.
- High accuracy due to ideally designed pressure range gradations
- Switching differences adjustable
- High long-term stability with a reproducibility of switching points < ±0.3 mbar
- Customer-specific switching points adjustable at the factory
- Rugged industrial switch with good price/performance ratio
- Best price/performance ratio
