Mechanical Differential pressure switch 630
The differential pressure switches of Type 630 are suitable for flow monitoring in sanitary and heating systems or for level control in general process engineering. The extremely robust design allows for a system pressure and a one-sided overload of up to 20 bar.
- High overpressure safety on both connections (P1, P2) up to 10/20 bar
- Functionally simple and robust mechanics with high operational reliability
- Also suitable for slightly aggressive liquids and gases
- Reproducibility up to < ±0.4 mbar
