Differential pressure, vacuum and overpressure switches of type 630 are suitable for monitoring neutral and slightly aggressive liquids and gases. Switching element isolated from medium. Ideal for use as flow monitor in sanitary piping/ heating installations or for level monitoring in general in process technology applications. Extremely rugged construction with high functionality due to 10/20 bar safety margin in both pressure chambres.
High overpressure safety margin at both connections (P1 + P2) up to 10/20 bar
Functionally simple, rugged mechanics with high operating reliability
Also for slightly aggressive liquids and gases
Repeatability up to < ±0.4 mbar
