Single & Dual Pressure Switch 1620 Series

Single & Dual Pressure Switch

 

The Dwyer 1620 Series switch design is 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.
