On the Series 1620 our old faithful switch design is still best where highest precision combined with diaphragm sealed leak proof construction and mounting simplicity are required. Model 1626 and 1627 differential pressure switches are identical in design and construction except that Model 1626 has a single electric switch and Model 1627 has dual electric switches. Model 1627 can therefore provide dual control when required. It can be set to open or close two independent electrical circuits, each preset for its own actuation pressure. Both units have diaphragm sealed motion take outs providing maximum protection against leakage.

Caution: For use only with air or compatible gases

• Single or dual action switches support consistent designs with similar models, but with the ability to match specific application needs
• Sealed diaphragm provides leak-proof construction for high accuracy and precision control
